Mineralogy in Copper Processing

 · In supergene-altered ores of the Copperbelt, transition ore zones occur between the supergene, oxidised ore and hypogene, sulphidic ore; the transition zone is thus host to both copper oxides and copper sulphides in important quantities, as shown in an example of ores from all three zones (Figure 3). Typical flotation only recovers the readily floatable sulphides; this is commonly used …

Copper-Lead-Zinc ores. The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage. In this case, as a general rule because both copper and lead minerals tend to float well, these are usually the
