摘要
超低品铜多金属矿是国内铜矿石资源的重要组成部分,该类型矿石自身赋存品位较低、回收难度较大,同时选别工艺指标要求较高、生产成本较高。针对某超低品位铜多金属矿6000 t/d选矿厂Ⅰ段磨矿分级系统运转率不足的问题,通过系统性的工艺技术改造、设备技术改造、生产精准化管理等,Ⅰ段磨矿分级系统运转率由90.29%提高到97.27%、提高近7个百分点;选矿厂年处理量提高15万t以上,有效回收铜金属300 t/a、铁金属8500 t/a、钼金属15 t/a,产生经济效益超过2500万元/a;达到了提高磨矿技术指标同时增加生产效益的目的。
Ultra-low-grade copper polymetallic ore is an important component of domestic copper ore resources.This type of ore has a low storage grade and is difficult to recycle.Meanwhile,it requires higher processing index requirements and higher production costs.Aiming at the problem of insufficient operation rate of I-stage grinding classification system in 6000 t/d concentrator of an ultra-low grade copper polymetallic ore,the operation rate of I-stage grinding classification system was raised from 90.29%to 97.27%and increased by nearly 7 percentage points through systematic technological transformation,equipment technical transformation production precision management;The annual treatment capacity of the concentrator is increased by more than 150,000 tons,and the effective recovery of copper metal is 300 t/a,iron metal is 8500 t/a,molybdenum metal is 15 t/a,and the economic benefit is more than 25 million yuan/a.It achieves the aim of improving the technical index of grinding and increasing the efficiency of production.
