from the slag through mixing copper slag with calcium oxide as fluxes and carbon as a reducing agent, then roasting the mixture at a temperature of about 1200–1300 C, followed by magnetic separation to recover iron from the copper flotation slag [18–22]. The smelting reduction process is a method where
Apr 13, 2021 Literature states that an iron grade that is considered viable for economic beneficiation should be at least 25% and this slag has an iron content above this limit, hence poses a serious environmental threat upon disposal

Jul 29, 2016 After simple beneficiation, such as froth flotation and magnetic separation, the percentage of iron in the form of magnetite increased from 32.86% to 65.12%, and that of copper in the form of magnetic copper and copper sulfide rose from 80.00% to 90.33%. The study demonstrates a good example of highly efficient recovery of metals from copper slag based on phase reconstruction

Mar 01, 2007 LD slag is a byproduct of steel industry, which comes from pig iron refining processing using LD converters. Because of its physical, chemical and mineralogical properties, it can be used as a substitute for aggregates in civil engineering projects. LD slag has the useful components like CaO, MgO with high basicities (CaO/SiO 2) of above 3.0. LD slag therefore has high fluxing capacity and is being
