Apr 17, 2020nbsp018332Sulphide ore dominated the global mining floatation chemicals market in 2019 as the sulphide ores are further used for extracting various minerals such as nickel, cobalt and copper
Using a range of ore samples from the same deposit the influence of mineralogy on flotation performance was studied. characterisation of the samples through qemscan showed that bornite, chalcopyrite, chalcocite and carrollite are the main copper-bearing sulphide minerals while carrollite is the only cobalt-bearing mineral.
This means that 95.7 of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. c the cu loss can be calculated by subtracting the cu recovery from 100 cu loss 100 95.7 4.3 this means that 4.3 of the copper present in the ore
