Title:
DOUBLE-REGION FLOTATION METHOD FOR COPPER-COBALT SULFIDE ORE IN INDUSTRIAL PRODUCTION
Document Type and Number:
WIPO Patent Application WO/2019/006889
Kind Code:
A1
Abstract:
Disclosed is a double-region flotation method for a copper-cobalt sulfide ore in industrial production. The sorting process uses a flotation process flow, wherein the flotation process uses flotation in separate regions, which are divided into two regions, region 1 is mainly used for concentrate index control, and region 2 is used for recovery rate control. The method achieves a high-efficiency recovery for both copper and cobalt elements in the copper-cobalt sulfide ore in the scope of industrial production, and by using the double-region stepwise flotation method, effectively relieves the contradiction between the recovery rate and the concentrate grade in the field of ore dressing, improves the efficiency of quality control, greatly improves the optimization efficiency of the recovery rate and concentrate product index, and achieves the relatively separate control of the grade and the recovery rate.
