摘要
Abstract
Aiming at the characteristics of a copper-iron ore,we adopt the process of first flotation and then magnetic process,together with the use of ester-112,which is a good selective collector,to realize the comprehensive recovery of the ore.Using the"first flotation-then magnetic"process,the original ore is ground to-74 μm 70%,copper circuit using one roughing,three cleaning for the output of copper concentrate.copper sweeping tailings after a magnetic separation output of iron ore concentrate.Closed-circuit tests obtained copper grade of 20.72%and recovery rate of 80.76%in the copper concentrate,gold grade of 43.91 g/t and recovery rate of 86.29%in the copper concentrate,iron grade of 66.38%recovery rate of 94.20%in the iron concentrate,among which the content of the harmful elements of the sulfur is only 0.16%.关键词
