Productivity in Copper Smelting and Refining



2012

ISASMELT ™ HIGH PRODUCTIVITY CLEAN SMELTING
The ISASMELT™ process delivers clean, cost-effective, high intensity smelting using a Top Submerged Lance (TSL). Xstrata Technology’s ISASMELT™ process provides an innovative, high intensity, yet
low cost submerged lance smelting process that is easy to operate. It can be used for a range of applications including primary and secondary copper smelting and copper converting, primary and secondary
lead smelting, primary nickel smelting and converting, and tin, zinc and precious metals smelting.

After more than 25 years of continuous development, the ISASMELT™ design provides all licensees with clean, effective and low cost smelting.

Model Helping Jhagadia Copper Limited  reduce cost of production by 8 – 10 %
TRDDC (TCS) proposed a model based optimization of JCL’s  Kaldo furnace resulting in a new furnace operating regime.
The solution has improved productivity by 10% and the refractory life by 50-60%. This has led to direct cost savings to the tune of 8-10%, enhancing the cost competitiveness of the company.

Jhagadia Copper Limited (JCL) is the largest producer of LME Grade “A” Copper Cathodes in India using secondary smelting route. The company was set up in technical collaboration with Outokumpu Technology
AB (formerly Boliden Contech AB), Sweden. The capacity of its plant is 50,000 MT per annum of copper cathodes (conforming to LME Grade “A” specification) and 20,000 MTA per annum of copper anodes. In terms of production, JCL has the largest secondary copper smelting plant and is the third largest copper producer in India.
