This relies on the difference in densities between the ore minerals and the gangue. This method has applications in various stages of a flowsheet from initial processing to final upgrading. Some of the earliest methods were utilized by the prospectors of the gold rush where they used simple panning techniques to concentrate their ore.
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 II chloride by means of which the copper minerals and some of the gold in the concentrate are made to dissolve.
