| 摘 要： | 采用浮选-浸出处理含铜2.09%的土耳其氧化铜矿，该矿有用矿物主要为孔雀石、蓝铜矿、硅孔雀石及少量硫化铜，铜矿物氧化率高，嵌布粒度较细，矿石易泥化. 通过浮选回收易浮的硫化铜和部分孔雀石和少量蓝铜矿，获得品位25.04%、回收率为57.25%的浮选铜精矿，浮选尾矿中的蓝铜矿和硅孔雀石采用硫酸浸出，含铜量由0.94%降至0.05%，浸出率达94.68%，实现了目的矿物的有效回收.

| Abstract: | A copper oxide ore from Turkey with copper grade 2.09% was treated by flotation and leaching. The ore contained useful minerals of malachite, azurite and chrysocolla, as well as a small amount of copper sulphide, and had high oxidation rate and fine dissemination of useful minerals, which was easily muddy. The copper sulphide and part of malachite and azurite were enriched by flotation. The concentrate grade of copper from flotation was 25.04% with the recovery rate of 57.25%. The azurite and chrysocolla that remained in the tailings were leached by sulfuric acid, and the grade of copper decreased from 0.94% to 0.05%, the leaching rate of copper was 94.68%, leading to the high recovery rate of useful minerals. |
