A mine renovated its old ore-dressing plant to realize the comprehensive utilization of mining waste rock and implements discontinuous operation that treats the mining waste rock in downtime. After the mining waste rock is through crushing,screening and gravity separation,mixed gravel and gravity gold concentrates are produced,creating net profits of 25. 91 yuan/t.the comprehensive utilization of mining waste rock realized the secondary recovery of solid waste resources. It also has significance in the safe and green operation of the mine and the construction of an world-class demonstration mine.
