摘要
李子金矿碎石子主矿体矿石储量大,约占总矿石储量的3/4,入选品位低,采用原磨矿、浮选工艺条件,浮选尾矿品位约达0.4 g/t、金精矿品位20 g/t。通过对磨矿、浮选工艺条件进行优化选择,对原工艺条件进行改进,使浮选尾矿金品位低于0.3 g/t、金精矿品位提高到60 g/t,每月多创效益15.6万元。
The reserve of Suishizi main orebody in Lizi gold mine is high and accounts for 75 % of the total reserves. With the former milling and floatation technical conditions, the grade of tailings is about 0.4 g/t and that of concentrate is 20 g/t. By optimizing the milling and floatation conditions, the grade of tailings is cut to below 0.3 g/t and that of concentrate increases to 60 g/t. It will bring more benefits of 156 thousand RMB per month.
