| Abstract: |
| A sandstone copper deposit in Mo Han, Yunnan contains 0.77% copper, in which oxide copper accounts for 45.45% of the metal rate. The main copper mineral is malachite. Due to its insufficient oxidation and highly mixed with limonite blending, the ore is relatively refractory.The flotation experiment results show that: 3000g/t lime as regulator and depressor, 1000g/t Na2S as activator, 90g/t butyl xanthate as collector, 35g/t pine oil as frother, under the grinding fineness of -0.074mm accounted for 85%, after 3 roughing-2 selecting- 1 roughing, we had a result of 18.006% grade and 80.01% recovery. |
