copper recovery from slag in india html

Copper Slag General Information, Process, Products

Copper slag is a by-product of copper production from copper ore. For every ton of copper produced about 2.2 ton of slag is generated. At present, across the world around 33 tonnes of slag is generated while in India three copper producers Sterlite, Birla Copper and Hindustan Copper produce around 6-6.5 tonnes of slag at different sites.
