一、前言铜录山氧化矿属于矽卡岩铜铁共生矿床,矿石氧化率高达97％,结合铜含量约10—25％,高达40％,并含有难选假孔雀石。矿石性质复杂多变,生产上一个班还可变几次,经十余年生产实践证明,采用硫化—黄药浮选,并加少量羟肟酸钠,生产指标虽不断提高,但幅度不大,铜精矿品位14～16％,回收率75～80％。为了使指标进一步改善,我矿曾与研究
I. INTRODUCTION Tonglushan oxide ore belongs to the skarn copper-iron symbiotic deposit. The ore oxidation rate is up to 97%, the copper content is about 10-25%, up to 40%, and contains the unparalleled false malachite. The complex and volatile nature of the ore, the production of a class can be changed several times, after more than 10 years of production practice has proved that the use of sulfide - Xanthate flotation, and add a small amount of hydroxamate, although the production indicators continue to increase, but not much range , Copper concentrate grade 14 ~ 16%, recovery rate of 75 ~ 80%. In order to further improve the indicators, I have worked with mining research
