The site consumed an abnormally large quantity of sodium hydrosul-phide NaSH in its Cu-Mo circuit. In one trial, Cytecs reagent AERO 8371 PNR was used as a copper
flotation reagents are mainly used to regulate the floatability of minerals. In the mining industry, cyanide is primarily used for leaching gold and silver from ores, but it is also used in low concentrations as a flotation reagent for the recovery of base metals such as copper, lead, and zinc at many of these operations, cyanide treatment systems may be required to address potential toxicity ...
Jun 15, 2020 The largest flotation recovery difference occurred at a pH 6, suggesting that molybdenite could be effectively separated from chalcopyrite using ferrate as the depressant. Fig. 1d shows the flotation recovery of copper and molybdenum in molybdenum bearing copper concentrate as a function of the ferrate concentration at pH 6.

On the other hand, NaHS also works as a depressant for chalcopyrite in copper and molybdenum selective flotation 3,34,35. In this study, we focused on the effect of NaHS as both activator and depressant for oxidized copper sulfide minerals and investigated the quantitative conditions of NaHS activation and depression.
Flotation experiments were carried out in a 2.5 L Denver laboratory flotation cell using a 1000 g ore sample. Pre-flotation was employed to remove some of the carbonaceous matter through adding diesel oil 120 gt and methyl isobutyl carbonyl MIBC 50 gt as collector and frother, respectively.

I experienced a copper-gold massive ore type where thionocarbamate seemed to work better. Also, SMBS is a common pyrite depressant. Dithionocarbamates are very selective in copper flotation. It will not float pyrite. Can be used at a slightly elevated pH 9. It is a common approach in copper flotation.
