INTRODUCTION:-

• Hindustan Copper Limited (HCL), a public sector undertaking under the administrative control of the Ministry of Mines, was incorporated on 9th November 1967

• Shri K.D.Diwan, Chairman-cum-Managing Director.• The Company markets copper cathodes, copper wire bar,

continuous cast copper rod and by-products, such as anode slime (containing gold, silver, etc.), copper sulphate and sulphuric acid.

• More than 90% of the sales revenue is from cathode and continuous cast copper rods.

• In concluded financial year 2006-07, as per provisional estimates, the Company has earned a all time highest net profit Rs 331 crore against a sales turnover of Rs 1800 crore.

UNITS OF HCL:-

• Khetri Copper Complex (KCC) at Khetrinagar, Rajasthan • Indian Copper Complex (ICC) at Ghatsila, Jharkhand• Malanjkhand Copper Project (MCP) at Malanjkhand, Madhya

Pradesh•  Taloja Copper Project (TCP) at Taloja, Maharashtra• Gujarat Copper Project (GCP) at Jhagadia, Gujarat

KHETRI COPPER COMPLE (KCC):-

• Khetri is situated at the foothills of the Aravalli Range.•  which hosts copper mineralization, giving rise to a 80 km

long metallogenetic province from Singhana in the north to Raghunathgarh in the south, popularly known as Khetri Copper Belt

• Khetri comprises of Khetri town and Khetrinagar. • Khetri town was founded by Raja Khet Singhji Nirwan, and

Khetrinagar, which is about 10 km away from Khetri town, is developed and maintained by Hindustan Copper Limited. 

KHETRI COPPER COMPLEX (KCC)

CAPICITY OF KCC:-

• Capacity 1.0 million tonnes of ore per annum.• Process plants to produce 31,000 TPA of refined copper

ORE OF COPPER

ROPE WAY:-

• It transports copper ore from Kolihan to Khetri plant.

• There are 55 tower and 6 substation.

• Total length of rope way is 15 km.• There are 65 buckets and capacity

of each buckets is 1 tonne.• Maximum speed of rope is 2.8 m/s.• Minimum speed of rope is 1.4 m/s.• Rope is drive with the help of 280

HP motor.

COPPER ORE BELT CONVEYOR:-

GRINDING:-

• Grinding is done in the Ball Mills and Rod Mills.

• The limits of particles from 5µs to 300µs.

• After grinding ore is forward for Forth Flotation.

• Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.

SPECIFICATION OF ROD MILL

Rod Mill are driven by a 920w,200 rpm ,3.3 KV synchronous motor.

Length of the Rod is 17 Feet.

The weight of Rods is 27 tons.

Output 200 MT/hr

SPECIFICATION OF BALL MILL

Ball Mill are driven by a 920 w,200 rpm ,3.3 KV synchronous motor.

The diameter of balls varies from 1’’ to 1½’’.

Maximum output of Ball mill is 200 MT/hr.

SLAG

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal

PRODUCTION FLOWCHART:-

COMPRESSOR HOUSE:-

• There are four KIRLOSKAR compressors and one is CAMERON compressor.

• Compressor house provides compressed air to the mines to drive different pneumatic motors.

• This is also makes mines place workable.

MMR SHOP:-

• In Mining Machine Repair (MMR) shop, the pneumatic motors are repaired which are used in mines.

• Assembly of pneumatic motors.

• Repairing of loaders.

CONCLUSION:-

• In review this internship has been an excellent and rewarding experience.  

• I have been able to meet and network with so many people that I am sure will be able to help me with opportunities in the future. 

•  One main thing that I have learned through this internship is time management skills.
