Effects of Some Additives on Copper Losses to Matte Smelting …
Copper is lost to slag between 0.7 and 2.3 wt.% during the industrial copper matte smelting stage. In the present study, the aim was to minimize these losses in the slag phase by adding some fluxing agents like CaO, B2O3 and calcium borate (namely colemanite—2CaO·3B2O3·5H2O). Eti Copper Inc. (EBI) flash furnace smelter slag …
