PRACTICAL TRAINING PRESENTATION ON

“Hindustan Copper Limited”- Khetri

Presented By: Name:- Pritam Singh Shekhawat Final yr.(ME-B)Roll no:-11EJAME074 .

HISTORICAL BACKGROUND :- It’s a GOVT. OF INDIA ENTERPRISES.

Discovered by G.S.I (Geographical Survey of India) in 1954.

Exporting mining by I.B.M (Indian B of Mines) in 1957.

Project handled over to N.M.D.C (National Mines and Development Corporation ) in 1961.

N.M.D.C transformed to H.C.L (Hindustan Copper Limited ) in NOV, 1967.

MAIN COMPONANTS OF H.C.L :-

1) Mining Section.

2) Concentrator Plant.

3) Smelter Plant.

4) Refinery.

5) Mine’s Machining Repairing Shop.

6) Gas Turbine.

7) Telephone Exchange.

COPPER MINING :-

Mining is the extraction of valuable minerals or other geological materials from the earth, usually in form of ore.

INSTRUMENTS USED :-

Underground battery-electric locomotives.

lift system.

UNDERGROUND BATTERY-ELECTRICLOCOMOTIVES

These run on 320 V DC traction lead-acid batteries which are usually recharged inside a depot.

They are used for hauling materials and equipment and were specially designed and built to work in narrow mines.

LIFT SYSTEM : - Lift system is basically

controlled by STEPPER MOTOR.

HCL has the asia’s 2nd largest STEPPER MOTOR.

A cage is connected to STEPPER MOTOR with the help of steel ropes.

Cage is lowered into various shafts inside the earth.

STEPPER MOTOR

A STEPPER MOTOR is a special DC Motor which can be run in both forward and reverse directions.

The main advantage of the motor is that, it can be stopped at any instant, which is not possible in the normal DC Motors.

A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed & torque, and protecting against overloads and faults.

Mine :-

• Depth – 370 m.• Ore is crushed inside the mine Aprox.

150 mm.• One surge tank is also situated inside the

mine which use to store the copper ore.• Process:- COPPER ORE LODDER

MACHING CRUSHING(150MM) SURGE TANK OUTSIDE THE MINE

CONCENTRATORo IT IS A PROCESS OF EXTRACTING

MAXIMUM AMOUNT OF COPPER ORE FROM THE ROCKS i.e TO INCREASE THE CONCENTRATION OF ORE.

INSTRUMENT USED IN CRUSHING :

THE NUT-CRACKERS, ROLLING-MILL, AND GRINDSTONE.—PRESSURE OF ATMOSPHERE.—SEED DIBBLES AND DRILLS

CONCENTRATOR

FEEDER

ROD MILL

HYDROCYCLONE

FROTH FLOATION

FILTRATION

SMELTER PLANT :-

AIM IS TO PROCESS THE CONCENTRATE INPUT –COPPER CONC.(27-28%) OUTPUT-ANODE COPPER (99.5%)

THIS PLANT HAS FOUR MAJOR PARTS AS :

FLASH FURNACE.

CONVERTER.

DRYER.

ANODE FURNACE.
