Integrated Technology for Processing Gold-Bearing Ore …
The results of the stage test showed that it is advisable to use a two-stage scheme for ore processing. The first stage of concentration in the grinding cycle (ore size 60–70%– 0.071 mm), the second at the final size (80%–0.071 mm). According to the GRG test, the ore is efficiently con-centrated by centrifugal methods.
