高浓度全尾砂胶结充填要求全粒级尾砂浓度达80％左右,回收率达90％。凡口铅锌矿全尾砂物料,通过小型试验,沉降速度仅为铅锌精矿沉降速度的1/8,采用传统的普通浓密机脱水时需一台直径100m的浓密机才能满足选厂尾矿回收率90％以上的要求,经多方案分析比较,决定采用高效浓缩脱水技术。为此,研制了新型高效浓密机。开始研
High concentrations of tailings cementing filling requirements of the whole grain tailings concentration of about 80%, the recovery rate of 90%. Through the small scale test, the settling velocity is only 1/8 of the settlement rate of lead-zinc concentrate. When the conventional thickener is used for dewatering, a thickener with a diameter of 100m is needed to meet the needs of the plant tail Mine recovery rate of 90% of the above requirements, the analysis and comparison of the multi-program, decided to use highly concentrated dehydration technology. To this end, developed a new type of high efficiency thickener. Start researching
