摘要
新疆中泰某金矿矿石以粗粒自然金为主,矿石矿物成分简单,以黄铁矿为主,少量黄铜矿、闪锌矿以及个别的磁黄铁矿。脉石矿物以石英为主,次为钾长石、斜长石以及黑云母、白云母。针对该矿石的特点,采用重选—浮选联合工艺流程,获得重选金精矿品位129g/t、回收率46.23%,浮选金精矿55.41g/t、回收率39.96%的较好指标,金总回收率为86.19%。
The major size of fine natural gold mine is coarse grain in Zhongtai of Xinjiang. The mineral com- position is simple. There is a large number of pyrite and a small amount of chalcopyrite, sphalerite and pyr- rhotite in gold ore. The main gangue mineral is quartz and a small amount of Potassium feldspar, plagio- clase, biotite and muscovite. It was done experiment of mineral processing research for the efficient exploi- tation of the ore. Experimental result shows that such kind of mineral is treated through the gravity--flo tation combined process, obtaining a gravity separation of gold concentrate containing 129 g/t Au with re- covery of 46.23% ;a flotation gold concentrate containing 55.41 g/t Au with recovery of 39.96% ;The total gold recovery containing 86.19%.
