Copper Flotation Recovery Rates of Oxidized Ores

A crude display of how oxide content (copper) affects the overall recovery of any given ores. Below are flotation recovery responses of 5 different ores from North and South America. In all cases, the recovery VS %Oxide relationship is obvious. Samples vary from 0.4% to 1.6% total copper. The heavy oxide chart (4th one down) being the 1.6% Copper. Notice the fairly content, 1 to 1 slope (0.89

Flotation of zinc oxide ores by cationic and mixed

Oct 01, 2012· 1. Introduction. The flotation of oxidized Pb and Zn minerals, particularly Zn minerals, is much more difficult than the flotation of corresponding sulfide minerals (Hosseini and Forssberg, 2007).The most common flotation technique used commercially for the treatment of ZnO minerals is sulfidization with Na 2 S, followed by treatment with conventional cationic collectors, namely amine
