Pb Flotation Copper

06/12/2015· By modifying Flotation pH to create kinetic/speed differences between the metals and achieve sequential flotation and take full advantage of the hydrophobic nature of each mineral, it is best to first lower the pH and see about recovering copper. MBS is the pH modifier of choice to dropping pH into a zone where Cu is hydrophobic while all other metals are

The source of Pb . 60 Centuries of Copper The Flotation Process. The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact in the last century ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce the great

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 target bulk

01/11/2019· Sulphide ores are the major source of valuable metals such as copper, lead, zinc, and nickel, as well as gold, silver, and platinum group metals (PGMs), and flotation is the dominant industrial process to recover these metals via the production of a sulphide concentrate.

Cu/Pb/Zn ores with high Ag/Au content (as lead flotation collector) Copper ores containing secondary Au and/or Ag values when the recovery of these metals can have a significant economic impact on the profitability of an operating plant whose primary products are base metal sulfide concentrates; Selective flotation of Cu at high pH from Ni/Cu ores

01/10/2019· In response to the high pyrite recovery in copper flotation using seawater, this study investigated the role of sodium metabisulphite (MBS), a widely used pyrite depressant, in depressing the flotation of copper-activated pyrite to identify a solution to maximising pyrite rejection. It started with chalcopyrite flotation against pyrite with MBS added in the mill before

Copper-cobalt oxide ores contain several minerals that are economically treatable by concentration techniques. The most used technique is froth flotation in which selective reagents are used to recover more valuables. It is, therefore, important to examine the optimal doses of those reagents while investigating the behaviors of minerals at the same time.
