Fig. 2 shows that as pH increased from 9.0 to 10.5 and then to 11.5, the pyrite recovery obtained from the flotation of the ore with 5 % pyrite decreased steadily from 94.5 to 40.6 % and then to 10.3 %. Hence, a direct link between the decreased pyrite recovery in Fig. 2 and the increased Cu grade in Fig. 1 when pH increased could be drawn. The decreased …
Copper alloy castings are used in applications that require superior corrosion resistance, high thermal or electrical conductivity, good bearing surface qualities, or other special properties. This article discusses the nominal composition and mechanical properties of copper casting alloys, designated in the Unified Numbering System.
Sulfide Copper Ores . Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.
Zanin et al., (2021) developed a model to calculate bed porosity and apparent density for two feed specific gravities (porphyry copper ore: 2.7 kg/m 3 and hematite hosted copper ore: 3.8 kg/m 3) and particle size values (coarse: −600 + 150 µm and fine: −210 + 75 µm) through Richardson and Zaki models modified by introducing more suitable ...
A large porphyry copper flotation plant has been simulated using a flotation model developed from first principles using the hydrophobic force as a kinetic parameter (Huang et al., 2022, Gupta et al., 2022).The input to the simulation was the size-by-class liberation matrix (m ij) of a flotation feed, which was essential for predicting the size-by-class flotation rate …
