1. Executive Summary:
Vedanta Limited (formerly Sesa Industries Ltd. and Sesa Goa Limited) got Environmental
Clearance (EC) F. No.J-11011/946/2007-IA-II(I) from MOEF on June 03, 2009 for following:
Sl. No. Facility Production Capacity
1 Mini Blast Furnace 9,00,000 TPA

4 Power Plant (Waste Heat Recovery) 60 MW
Amendment in EC was granted by MOEF on 25th April 2012, with comments:
Project will be implemented in two phases (with exactly half the production capacity in
each phase) and
Change in the plant configuration with particular reference to stack dimensions with
reference to height and diameters without change in production capacity.
Consent to Establish (NOC) was obtained from Goa State Pollution Control Board (GSPCB)
for following:
Sl. No. Description Quantity
1 Mini Blast Furnace 0.45 Million Tons/annum
2 Sinter 01 Million Tons/annum
3 Coke Oven 0.3 Million Tons/annum
4 Power Plant (Waste Heat Recovery) 35 MW
Accordingly, all the units mentioned in CTE/ NOC were commissioned and Consent to
Operate for respective units with production quantities were obtained from GSPCB
Six monthly EC compliance reports were submitted on regular basis which were verified by
MOEF (SZO) & GSPCB officials periodically.
In 2014-15 hot metal production of 376947 tons was achieved, which is the highest since
commissioning of Blast Furnace in August 2012
PFR for enhancement in the production capacity of blast furnace from 4,50,000 TPA to 5,40,000 TPA by process optimization and efficiency
Vedanta Limited, Goa Page 4
With in-house experiences in operating the blast furnace and experience gathered from other
similar BF operating in India, it has been inferred that hot metal production can reach upto
0.54 MTPA with the existing Blast Furnace.
The 450 m
3 Blast Furnace was designed for foundry grade production having around 2% Si,
primarily catering to auto industry for different castings manufacturing. Due to sudden fall of
demand in automotive sector, foundry grade pig iron market shrunk drastically. Also Ferro
silicon prices got affected due to fall in steel market. To reduce cost of production many of the
manufacturers have started using semi-foundry or basic grade pig iron having lesser Si% and
explored addition of ferro silicon to metal after melting of pig iron in cupola or induction
furnaces. Current market scenario has favored the auto industry to optimize cost of
manufacturing the castings.
Since there was over all shortage of demand and China has started dumping steel in India
which was cheaper option for different consumers in India. This resulted in pushing primary
steel producers to produce pig iron as there was stiff competition in steel production cost and
Indian steel producers were not competitive against the imported steel from other countries.
This resulted in heavy inventories of pig iron in India. Looking in to the scenario and taking
advantage of strategic location where in sea transport is viable option, management has
taken decision of exporting basic grade pig iron in big way. Although there was competition
from primary steel producers, Goa being very close located to sea and good water bound
logistic infrastructure in place was an advantage there by making Sesa / Vedanta compete
with big steel manufacturers.
The process optimization will not add to the cost of the BF project. The cost of blast furnace is
about Rs.400 Crores. Therefore without spending any extra CAPEX, annually around 90, 000 to
1,00,000 tons of hot metal could be produced.
The cost of production of foundry grade pig iron by Indian Producers is more than the sale
price of China. In order to remain sustainable, profitable and socially viable, the company
decided to produce basic grade pig iron. The demand of basic grade pig iron at competitive
cost exists in the domestic and international market.
PFR for enhancement in the production capacity of blast furnace from 4,50,000 TPA to 5,40,000 TPA by process optimization and efficiency
Vedanta Limited, Goa Page 5
The proposal will save direct employment for about 150 people and add another 25 direct
employment. It will also add about 100 indirect employment in the transportation sector.
The existing Blast Furnace of 450 m3 volume and 4,50,000 TPA production capacity is already
operating. The production capacity enhancement to 5,40,000 TPA through process optimization
could be done without stopping the BF. It will be completed within 1 month of getting EC
amendment.
This production increase can be achieved through increased injection of wind volume, oxygen
enriched blast, charging sinter feed upto 90%, better process control in operations, etc.
without any change in Blast Furnace nor any modernization or change of product mix.
With increase in production capacity from 0.45 MTPA to 0.54 MTPA, there will be no increase
in stipulated water consumption, neither the pollution load on air, water and land environment
will increase.

2. Introduction of Project / Background Information:
(i) Identification of Project and Project proponent.
Name of Project: Production Capacity Enhancement of Existing Blast
Furnace from 4,50,000 TPA to 5,40,000 TPA.
Category of Project: “A” Category.
Project Proponent: Vedanta Limited (Formerly Sesa Industries Ltd /
Sesa Goa Limited)
(ii) Brief description of nature of the project:
The volume of existing blast furnace is 450 m3. The licenced production
capacity is 4,50,000 TPA. Technology supplier of the BF is China. The
maximum hot metal production achieved in a single day is 1476 tons.
It has been observed from the existing BF as well as similar BF
technology installed at other plants in India (by MCC Overseas China)
that through appropriate process optimization the production capacity
could be increased by 20% to 5,40,000 TPA. This could be achieved by
increasing the hot blast volume, by increasing oxygen blowing and
increasing the Fe content in sinter burden.
There will be no change in the process technology, general layout and
water consumption. The plant area will remain same. Technically, the
pollution load discharged into the environment will also remain same.

Vedanta Limited, Goa Page 7
(iii) Need of Project and Importance to the Country or Region:
The existing BF produces foundry grade pig iron for automobile sector.
Hot metal is tapped into ladle and poured in the Pig Casting Machine.
Productivity rate of foundry grade pig iron using BF is low as compared
to productivity of basic grade pig iron using the same blast furnace. This
is mainly because of strict process control requirement in making
foundry grade pig iron.
The automobile sector is experiencing slowdown in India as well as in
other countries. Therefore the sale price of foundry grade pig iron is low
thereby affecting the sustainability / economic viability of the project.
Presently China started dumping low cost foundry grade pig iron in India
and other international market. The cost of production of foundry grade
pig iron by Chinese suppliers is lower than Indian Producers.
In order to remain competitive in the domestic as well as international
market, Vedanta Limited decided to start making basic grade pig iron
from the existing blast furnace.
This will make the project sustainable, profitable and socially viable. The
general product will meet the demand of India as well as international
market.

Vedanta Limited, Goa Page 8
(iv) Demand – Supply Gap:
The automobile sector is experiencing slowdown in India as well as in
other countries. Therefore the demand of foundry grade pig iron for use
in automobile sector has reduced.
Presently China started dumping low cost foundry grade pig iron in India
and other international market. The cost of production of foundry grade
pig iron by Indian Producers is more than the sale price of China.
In order to remain sustainable, profitable and socially viable, the
company decided to produce basic grade pig iron. The demand of
general grade pig iron at competitive cost exists in the domestic and
international market.
(v) Imports Vs Indigenous production:
The cost of production of foundry grade pig iron by Indian Producers is
more than its counterparts in China. The Indian Government is not
considering any additional import duty to be levied on steel/scrap
imported into India.
(vi) Export Possibility:
The project is located close to Major Port. This will enhance the export
chance by remaining cost competitive.
(vii) Domestic / Export Markets:
Railway line exists till Madgaon in Goa. This will make the product
competitive in domestic market like Maharashtra and Karnataka.
The project is located close to Major Port. This will enhance the export
chance by remaining cost competitive.

Vedanta Limited, Goa Page 9
(viii) Employment Generation (Direct & Indirect) due to project:
The company decided to produce basic grade pig iron from the existing
blast furnace. The raw material consumption would increase. Slag
generation would also increase proportionately.
Handling and transportation of additional raw materials and slag would
attract additional employment, both direct as well as indirect. The
additional direct employment would be about 25. The additional indirect
employment would be about 100, most of them in the material (raw
materials, product and slag) transportation sector.

9. Analysis of Proposals (Final Recommendations)
(i) Financial and social benefits with special emphasis on the
benefit to the local people including tribal population, if any in
the area:
Financial Benefit
The process optimization will not add to the cost of the BF project. The cost of blast
furnace is about Rs.400 Crores. Therefore without spending any extra CAPEX,
annually around 90,000 to 1,00,000 tons of hot metal could be produced.
Social Benefit
The automobile sector is experiencing slowdown in India. Therefore the demand
of foundry grade pig iron for use in automobile sector has reduced. Presently
China started dumping low cost foundry grade pig iron in India. The cost of
production of foundry grade pig iron by Indian Producers is more than the sale
price of China. In order to remain sustainable, profitable and socially viable, the
company decided to produce basic grade pig iron. The demand of general grade
pig iron at competitive cost exists in the domestic and international market.
The proposed project will save direct employment for about 150 people and add
another 25 direct employment. It will also add about 100 indirect employment in
the transportation sector.
The existing Blast Furnace of 450 m3 volume and 4,50,000 TPA production capacity
is already operating. The production capacity enhancement to 5,40,000 TPA through
process optimization could be done without stopping the BF. It will be completed
within 1 month of getting EC amendment.

ANNEXURE 4 : PROJECT DESCRIPTION, PROCESS DETAILS & SCHEMATIC
FLOW CHART
Project Description Transportation of raw material from storage yard to the stock house is done by closed belt
conveyors. The raw materials are distributed into the respective bunkers through shuttle
conveyors located at the top of the stock house bunkers. All materials, stored in different
weigh hoppers is charged sequentially into collecting conveyors which is discharged into
common charging conveyor which in turn feed the material to the blast furnace top charging
equipment. The hot blast stoves are designed for a blast temperature of 1250°C. Combustion
air and combustion gas is pre-heated by heat recovery system using BF gas from the stoves.
A blast furnace (BF) is an enclosed vertical furnace into which the raw materials enter at
the top, while the products (molten iron and slag) are tapped from the bottom (the
hearth).The raw material mixture of iron bearing materials (iron ore lump and sinter) and
additives (slag former, such as limestone) is called the “burden”. The burden and coke are
fed into the top of the furnace via a sealed charging system to prevent furnace gases from
escaping. Coke reduces iron ore to iron and also supplies heat. Iron ore gets converted to
iron and impurities are converted to slag. The solid burden moves downwards, counter
current of a rising stream of hot reducing gas. The hot reducing gas is provided by hot
stoves and is needed to transfer heat to the solid burden in order to raise the
temperature for reaction. The BF gas with residual calorific value is collected from the top of
the furnace for treatment and use.
The blast furnace is periodically tapped to remove the hot metal iron and slag from the
earth. For this purpose a tap-hole is opened in the side wall of the hearth. The tapped metal
has a temperature of approximately 1440-1500 °C. The slag and hot metal from the furnace
flows along the refractory or low cement covered runners and they are subsequently
separated at the skimmer in the cast house, after which each continues in a separate
runner. Liquid Hot metal is poured into ladles or torpedo cars. Slag flows in runners to a
granulation plant. At the end of casting cycle, the tap hole is closed by injecting a heat
resistant tap hole clay mixture, using a so-called “mudgun”.
Blast furnace gas is reused as fuel in the blast furnace stoves. The molten iron is converted to
pigs in Pig Casting Machine.

Production Capacity Enhancement Process Details
In 2014-15 the hot metal production from the 450 m3 blast furnace was 376947 tons, which is
the highest since commissioning of Blast Furnace in August 2012. With in-house experience
in operating the blast furnace and experience gathered from similar blast furnaces (Uttam
Galva, Jindal Steel, etc), it has been confirmed that the hot metal production can go upto
5,40,000 TPA.
This production increase can be achieved through increased injection of wind volume, oxygen
enriched blast, charging high Fe sinter feed upto 90% and better process control in operations
(without any change in Blast Furnace structure or change of product mix).
It is possible to enhance the productivity of existing blast furnace in five steps, described
below:
i. Production enhancement from 4,50,000 TPA to 4,62,143 TPA can be done by
producing only basic grade material. Production of foundry grade material will be
stopped / reduced.
ii. Production enhancement from 4,62,143 TPA to 4,76,007 TPA can be increased after
charging 2% increased Fe from current level of 54.25% to 56.25% (Fe can be
increased upto 60% in the same blend mix.).
iii. Production from 4,76,007 TPA to 5,30,487 TPA can be increased after increasing
wind volume from current level of 75000 Nm3/h to 85000 Nm
3/h. (Wind Volume can
be increased upto 90000 Nm3/h) as per design capacity of existing blowers in blast
furnace)
iv. Production from 5,30,487 TPA to 5,33,987 TPA can be increased by increasing
gaseous liquid Oxygen availability from current level of 3000 Nm3/h to 3200 Nm
3/h by
vaporizing current available liquid oxygen.
v. Production from 5,33,987 TPA to 5,40,000 TPA can be increased after improving plant
OEE from current 93.29% to 94.50% (OEE can be increased upto 97%)

When producing basic grade pig iron suitable for export it has also helped in increasing
production from usual level of 33000-34000 TPM to around 37000-38000 TPM. This
production level is almost close to our EC limit of 45000 TPA. The BF have potential to push
another 10000-15000 Nm3/hr. wind in blast furnace through optimization of burden
distribution, better quality of raw material usage and better process control. With this
additional 6000-7000 TPM production could be achieved. In the design given by technology
provider there were bottlenecks in hot metal evacuation which were resolved by putting up an
additional PCM and some modifications in ladle placement and handling schemes. With all
process improvements / optimization in place, the BF could produce around 45000 TPM or
5,40,000 TPA Metal.
After starting the plant as mentioned above there were restrictions on wind volume till October
2014 and also there were other teething issues in various equipment’s like conveyors, break
downs of equipment’s, frequent leakages in blowing systems etc. thereby dragging the
availability of plant below 90%. After stabilization of plant we have improved the availability of
plant to 94% and few projects in hand will improve it further to >97%. Thus there will be
another boost in production on this account.
There is no requirement of any additional facility per say for achieving this but improvements/
modifications in existing systems. Equipment’s available are having enough cushion to
support this higher production volume.
Pollution control devices are capable enough to handle this additional production level and
there will be no impact on environment on this account.
Blower which is main equipment decisive for augmenting the production level was selected
slightly on higher side during finalization stage itself, so this higher production is possible and
there no additional equipment cost coming for us. The Blower is designed for pushing around
100000 Nm3/h of wind.
Tomorrow when market becomes better we may switch over back to foundry grade
production but till that time it is paramount important for us to sustain in the market. This is
possible only buy controlling cost of production which comes through basic grade production
