Flotation tests showed that chalcopyrite flotation rate, recovery and grade, as well as the pulp oxidation potential, decreased with increasing pyrite content whilst pyrite recovery increased. Surface analysis (XPS, ToFSIMS and EDTA) indicated that copper activation of pyrite increased with increasing pyrite content, facilitating pyrite recovery.

Pyrite as the most abundant sulfide mineral is often associated with valuable sulfide minerals, coal and gold. It is very important to study its electrochemical behavior in the flotation process. This review focuses on researches carried out over the past several decades that have studied electrochemical processes associated with pyrite occurring during flotation.

A series of tests were conducted in which the parameters for conditioning with ahead of pyrite flotation were varied. The results of these tests summarized in Table 5 indicate the process to be operable across a range of conditions, although the use of conditioning times of less than 20 minutes appeared to result in increased arsenopyrite floatability.

LowerpH Copper Flotation Reagent System Department of Energy. New Reagent System Improves Recovery, Reducing Energy Use and Air In the mining industry, flotation is a process that concentrates minerals from their ores at a much lower pH than conventional reagents and avoids floating pyrite.
on its flotation was studied in a typical copper ore. A twostage (Cu and pyrite) rougher flotation indicated that maximum Au recovery (95%) can only be achieved with pyrite flotation (recovery, 93%). A decrease in grind size of the flotation feed from 70 µm to 38 µm and without pyrite flotation stage
