Flotation of oxidized copper ores Inspiration.These tailings contained 0.02 sulfide copper minerals and 0.08 oxidized copper minerals so that the overall recovery of copper in the rougher concentrate was 91.5 of the copper content of the ore, made up of 97.9 by weight of the sulfide minerals and 67.9 by weight of the oxidized minerals of the ore. EXAMPLE II
Combined Effect of Operating Parameters on Separation.Sep 24, 2018 This study aims to investigate the effects of operational variables on concentrate grade, recovery, separation efficiency, and kinetic parameters of the copper flotation process. For this purpose, the effects of the pulp solids content, collector and frother dosage, and preparation and concentrate collection time were studied using a Taguchi experimental design. The results of statistical ...

In the first flotation stage, as much copper as possible is recovered in a rougher concentrate so that as little as possible goes to the tailings. To increase the copper recovery rate, often these tailings are leached with sulfuric acid. After regrinding, the rough concentrate is
Gibraltar CopperMolybdenum Project Mining.A rougher concentrate is together produced by two parallel rougher flotation banks. The rougher concentrate is processed and upgraded through a two-stage flotation clean circuit. A bulk concentrate with both copper and molybdenum is thickened to separate the two minerals using differential flotation.
