COPPER SLAG
- Copper slag is a blasting abrasive obtained from Mineral Slag which converts itself into Iron Silicate during the smelting and quenching process in the Copper Smelter.
- The raw material iron silicate is generated by quenching of the slag in water in a specially designed granulator at Copper Smelter. This slag is stored in our factory as discrete piles to effect primary solar drying. This slag is analysed periodically for its chemical composition and is reported in the test certificate which is shown below.
