when gold dissolution is complete, the gold-bearing solution is separated from the solids. with ores of higher gold content cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
the gold content of a good grade gold ore may be only a few one-hundredths of a percent. therefore, the next step in mining is grinding the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called
gold. In southern africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. while the input material has an average gold content of less than 0.8 gt, the sorted product achieves a concentration of more than gt with an efficiency of approximately 90%.
