Gravity separation and cyanidation combined process was applied on the hydrothermal alteration types gold ore in Xinjiang Province.The test results revealed that coarse gold concentrate with grade of 311.70×10-6 and recovery of 42.23% was obtained using Knelson centrifugal separator under the conditions of gravity value of 60 and fluidzed water volume of 3.5~4.0 L·min-1.Gold leaching efficiency of gravity separation tailings was 97.41% using cyanidation process under the conditions of milling size of -0.045 mm 90%,cyaniding time of 24 h and pulp density of 40%.Therefor, the total recovery of gold ore was 98.81% using gravity separation and cyanidation combined process.
