In order to improve the environmental protection standard of a gold concentrator, increase ore processing capacity, the original process of mixed bearing all slime cyanidation carbon slurry process in the concentrator was transformed into Nielsen gravity separation mixed flotation process. Through technical transformation and chemical technology, such as replacing the straight line division and canceling the mixing process, the ore processing capacity is increased from 450t/d to 700t/d，the recovery rate of Nielsen gravity separation reaches 52.74%, the comprehensive recovery rate of gold is 96.60%, and the production index is good.
