Gold ore dressing process After mining large blocks of natural gold ore are first roughened by jaw crusher then under the action of conveyor they are evenly sent to the ball mill for deep grinding treatment after grinding the gold powder needs to be reasonably screened by the spiral classifier and the qualified materials after screening are sent to the flotation machine for separation

The flotation test at a P80 of 205 μm yielded a mass recovery of about % and corresponded to a gold recovery of % This lower recovery may in general be attributed to floatability problems of coarse particles The floatability by particle size curves for sulphides indicate significant drops around 200 μm Trahar 1981
