Abstract
A method for the pyrometallurgical processing of a sulphide material containing copper, the sulphide containing relatively high quantities of silica and relatively low quantities of iron, wherein the process comprises feeding the sulphide material to a TSL furnace operated under oxidising conditions such that the sulphide material forms blister copper containing between 1.2 and 1.5 wt % sulphur and a slag containing between 7 and 13 wt % copper.
Claims13
A method for the pyrometallurgical processing of a sulphide material containing copper, the sulphide containing between about 10 wt % and 40 wt % silica and less than approximately 20 wt % iron, the method comprising feeding the sulphide material to a top submerged lance furnace operated under such conditions that the sulphide material forms blister copper and a slag having a CaO/SiO2 ratio of between 0.30 and 0.55 by weight and an SiO2/Fe ratio of between 1.8 and 2.8 by weight.
