摘　　要：针对锡石多金属硫化矿磨矿过程中出现的锡石"过磨"问题,从研究锡石多金属硫化矿沉降特性入手,考察了沉降时间、沉降高度和矿浆浓度对沉砂产率的影响,获得不同粒级磨矿产品沉降规律,为提高分级效率和降低锡石"过磨"提供理论指导。Aiming ores, the effects of at the problem of cassiterite overgrinding during the grinding process of cassiterite-polymetallic sulfide settling time, settling height and pulp concentration on sediment yield were investigated in terms of the settling properties of cassiterite-polymetallic sulfide ore. Therewith, the settling laws for grinding products within different size range were obtained, which can provide a practical theoretical guidance for improving classification efficiency and releasing the extent of cassiterite overgrinding.
