Extraction of gold from refractory gold-bearing ores in processing with combined flow charts is higher if more gold is extracted by gravity methods before flotation and hydrometallurgical circuits. The article presents the results of gravity beneficiation of refractory gold-bearing ore from the Aktobe deposit with the cyanidation-recoverable gold content of 46.47%. Assessment of the gravity separation efficiency used the GRG-test which found that 35.93% of gold could be extracted in centrifugal concentration. Two flow charts of gravity concentration of ore in the grinding circuits with jigging and centrifugal concentration were tested. The studies find out that the main amount of Aktobe gold has a size less than 0.1 mm, and it is recommended to recover such gold by combining grinding and centrifugal concentration in the integrated processing circuit.
