DetailsAs a result, the flotation is difficult to occur and the minerals are inhibited. (3) In the process of flotation, adding reagents that are easier to oxidize than the collector can form a conjugate reaction with oxygen, which can consume oxygen. This process can also reduce the floatability of minerals and inhibit the minerals.
DetailsThe problem of treating oxidized lead-zinc ores for the production of high-grade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals.
