3.10 Resource Optimization / Recycling and Reuse Envisaged in the ProjectThe following will be done






PAGE-16

The mineralized waste generated during the mining period will be backfilled in order toreduce the change in land cover or topography of the area. This backfilled area will beused for greenbelt development

Complete backfilling is not possible so a part of mine out area will be used as waterreservoir and stored water will be used for watering the plantation and for dustsuppression. In addition to this water stored in mined out pits will be used by farmers andvillagers in nearby area thus reducing the ground water dependency.

Mine will be worked only in day time (8 hr/ day) and around 63 persons will work,therefore the domestic waste generated will be low and it is possible to recycle. As itdoesn’t require electricity because working will be only in Day time.

3.11 Availability of Water its Source and Energy/Power RequirementWaterFor domestic use water will be supplied by the means of tankers from the nearby village.For greenbelt development and dust suppression water stored in mined out pits will be used.For domestic purpose: 1.84 KLDFor dust suppression: 36.96 KLDFor plantation: 0.2 KLD

Fuel/Power RequirementThe mine will be worked during an eight hours shift i.e. during day time only and hence noelectricity is required for lighting. Diesel, ~3 lit/hr will be used as fuel for running pump fordewatering in rainy season that too for some time.

3.12 Waste Generation and ManagementNature of Waste & Rate of yearly generationIn the proposed mining scheme the OB is likely to be generated during scheme period will beSoil and will be spread on backfilled area.The waste that is likely to be generated will be in the form of associated clay with the bauxitehorizon as mineral waste which is below the threshold grade, which has no sale value. That willbe backfilled in mined out pits.

Quantity of WasteThe waste generated during scheme period will be as under:

Selection of Dumping SiteIn the proposed mining scheme, it is proposed that waste generated during scheme period willbe dump separately on pit floor plate no. 7 of mine layout plan. Top soil will be used forspreading on the back filled area for plantation purpose and in statuary barrier. Part of minedout land will be used as water reservoir.Method of Dumping & Maximum Height and Spread of dumpsThe backfilling will be done in the area after winning full thickness of bauxite. The propose areafor backfilling will be proved barren. The OB of waste generated during scheme period will beback filled in the mined out area in west part of the lease area. The waste generated duringthree years mining scheme period will be backfilled in mined out area at the time of generation itself question of its height and spread does not arise. The soil will be spread on the backfilledarea. As volume volume of voids (area to be worked) is much more than material available forbackfilling of backfilling of entire mined out land upto original ground level will not possible.Therefore waste part of the area will be backfilled and another part of the lease area will beused as water reservoir.

8 PROJECT SCHEDULE AND COST ESTIMATES

8.1 Project ScheduleThe mine lease is working site of OAL however; OAL will start production at proposed rate onlyafter obtaining necessary clearance from Central and State Government

8.2 Estimated Project Cost along with Analysis in Terms of Economic Viability of theProject

Estimated cost of the project would be around Rs. 54.39 lacs only. This cost includes the projectexpenditure towards the laterite and bauxite mine. The mine has been sanctioned by theGovernment for captive consumption only and not for sale of products; hence the profitabilityfactor does not arise at this stage. The cost break-up is given in Table 1.27.

9 ANALYSIS OF PROPOSAL (FINAL RECOMMENDATIONS)

9.1 Financial and Social Benefits with Special Emphasis on the Benefit to the Local Peopleincluding Tribal Population, if any, in the Area

Critical analysis of the existing socio-economic profile of the area vis-à-vis its scenario withproposed project activities identifies the following:About 98 miners will be engaged in mining activities for the project and about 60 people forancilary activities.The proposed activities shall generate indirect employment in the region due to the requirementof workers in supply auxiliary such as higher machinery service and Ore Transport serviceafford from the ancillary works, which would marginally improve the economic status of thepeople.Further the additional benefits from the downstream units such as iron industry, steel industry,cement plant, and metallurgical industry also add value to the society.
