depressors in mineral processing

polymetallic ores Use of organic depressors for

2011-5-30  A series of processing technologies have been developed in the Gintsvermet Institute for- selective flotation of copper-nickel, polvmetallic and copper-zinc ores. They are based on the use of low-molecular weight organic depressors ensuring efficient adjustment of selective separation of iron ,ferrous minerals and iron sulfides- In the process of

The depressing role of sodium alginate in the flotation of ...

The surface density discrepancy of aluminium hydroxides and unsaturated O between these two minerals played a key role in the flotation separation process. Moreover, NaAl could also selectively adsorb on galena surface through interfering with surface Pb 2+ thus exhibiting depression effect in the flotation of chalcopyrite [22] .

X-ray Photoelectron Spectroscopy in Mineral Processing

Surface phenomena play the crucial role in the behavior of sulfide minerals in mineral processing of base and precious metal ores, including flotation, leaching, and environmental concerns. X-ray photoelectron spectroscopy (XPS) is the main experimental technique for surface characterization at present. However, there exist a number of problems related with complex composition of natural ...
