本文介绍用离心力回收细粒矿物的研究。做了密度范围在5～19.3克/厘米~3之间的重矿石与硅石分离效率的理论分析。粒度为1～5微米的锡石和硅石分别代表重矿物与轻矿物,结果得到典型回收率为95％以上,纯度80％。这与理论预测结果一致。还表明,在更高 PH 范围内重矿物分散得更好,在 PH This article describes the study of the recovery of fine-grained minerals by centrifugal force. The theoretical analysis of separation efficiency of heavy ore and silica with densities in the range of 5-19.3 g / cm3 was done. Cassiterite and silica with a particle size of 1 to 5 μm represent heavy minerals and light minerals, respectively. As a result, a typical recovery rate of over 95% and a purity of 80% were obtained. This is consistent with the theoretical prediction. It has also been shown that heavy minerals disperse better at higher pH
