锡石与伴生硫化矿物沉降特性试验研究

Study On Settling Characteristics of Cassiterite and Associated Sulphides

采用自制的新型沉降实验装置,考察了沉降时间、沉降高度、矿浆浓度等因素对锡多金属硫化矿中锡石与伴生硫化矿物沉降特性的影响,获得了锡、锌和铅锑3种精矿在水介质中的沉降规律特征,为现场提高磨矿分级效率和降低锡石"过磨"提供理论指导。

A new-style self-made experimental facility was used to investigate the effects of settling time,settling height,pulp concentration on the settling characteristics of cassiterite and associated sulphides in multi-metallic sulfide ores.In this case,the settling laws of Tin,Zinc and LeadAntimony concentrates were obtained in aqueous medium,which provided theoretical guidance in practice for improving the classification efficiency and reducing overgrinding of cassiterite.
