Characterisation and leaching behaviour of granulated iron silicate slag constituents

Due to increased copper production and the associated environmental consequences, processes need be improved, considering impact of their byproducts, among others slag. This study investigated leaching individual constituents iron silicate slag from a smelter. was done by characterising granulated samples its – glass, matte, speiss determine contribution. It observed that in distilled deionised water without pH regulation achieved various natural for constituents. At pH, glass (Cu, Zn) (Ni, Sb) contributed leaching. Static titrations showed Zn, Cu, Ni, As, Sb with decreasing pH. The results that, an consisting matte speiss, contributes as follows: Cu Sb. Zn is similar
