1results about How to "Reduce mutual inclusion" patented technology

The application discloses a galena combined inhibitor and a use method thereof, and the combined inhibitor comprises iron sulfate, sodium nitrate and jarosite, and the mass ratio of the amount of the iron sulfate, the sodium nitrate and the jarosite is 20:(4-10):(1-2). The combined inhibitor can be applied to separation of copper-lead mixed concentrate to realize lead inhibition and copper floating, and the combined inhibitor does not need to be removed. In an acid medium, after the combined inhibitor acts, not only can the combined inhibitor decompose the adsorbed reagent on the surface of the copper-lead mixed concentrate, but also can promote the galena surface to be oxidized to generate hydrophilic PbSO4 and PbO, while the chalcopyrite surface is oxidized to generate hydrophobic elemental sulfur (S 0 ), thereby expanding the floatability difference between the copper-lead sulfide, the jarosite is selectively adsorbed on the surface of the galena, further reducing floatability of the lead, and improving the copper-lead separation efficiency. The copper concentrate and the lead concentrate obtained by the application have high recovery rates, low mutual content, reusable acid liquid, low cost and environmental protection.
