Beneficiation process for increasing recovery rate of gold of refractory gold ores

The invention relates to a beneficiation process for increasing the recovery rate of gold of refractory gold ores. According to the process, a reselection-floatation-reselection combined procedure is adopted to increase the recovery rate of the gold, and in other words, ores are ground till the particle size is -0.074 mm(60-80)%; a hydraulic power classifier is firstly utilized for classification, coarse gold concentrate is obtained from classified setting sand through a reselection method, and reselected tailings return to a ball mill to be ground gain; and classified overflow adopts a total-sulfur flotation method to recycle the gold, mustard gold concentrate is obtained, flotation tailings are reselected through a Nilson centrifugal ore separator, and obtained reselected concentrate returns to the ball mill to be ground gain. Early recovery and much recovery of the gold can be achieved through the process, gold which cannot be recycled because the particle size is too large or too small in total-sulfur flotation is effectively recycled, the purpose of selective ore grinding is achieved through reselection-ball mill closed cycle, the dissociation degree of the ores can be improved easily, the grade of the gold concentrate is remarkably improved, the metal recovery rate is remarkably increased, and good economic benefits can be brought to enterprises.
