Floatation experiment in Wushan copper Mine shows that isopropyl xanthogen ethyl formate has higher recovery ratio and higher copper grade than xanthate when they are used as copper sulfide collector.
The floatation-ore concentrate cyanidation process is usually used for vulcanized primary ore and the ores with low silt content and high recovery rate that are easy to concentrate during floatation.
