extracting machine used to separate gold from rocks. removing the goldbearing rock from the ground is just the first step To isolate pure gold, mining companies use a complex extraction process the first step in this process is breaking down large chunks of rock into smaller pieces At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravelthe gold ore is crushed and ground to the pointed particle size. with the grinding equipment, the gold ore is fed to the flotation cell with the sodium carbonate as a modifier and the butyl xanthate and butylamine aerofloat as a collector for separating the useful minerals and gangue minerals by the different hydrophobic of the mineral surface
apr 24, 2019 most of the gold is traded in dubai, home to the uaes gold industry. the uae reported gold imports from african countries for 2016. Of those countries, the invention relates to a method for recovering gold from a sulphidic concentrate, particularly one containing arsenopyrite andor pyrite, hydro- metallurgically. the concentrate is first subjected to leaching with a concentrated solution of alkali chloride and copper chloride, by means of which the copper minerals and some of the gold in the concentrate are made to dissolve.
