Ytc The Malaysia Lo Fine Cassiterite Flotation Reagent Optimization

Datun mineral processing plant is main production unit of YunXi Group Corporation.The floatation research work of exploiting Da Malu Oxide ore resource is the important component of exploiting resource to take experiment research in all respects.How to improve the concentration of fine tin ores has troubled us for many years. Many tin ores contain calcite, quartz in considerable quantity.the presence of calcite, quartz could seriously a acting mechanism of these collectors on minerals were investigated.In this paper the mechanisms of cassiterite flotation of SHA and several other collectors have been studied. First,the flotation behavior of cassiterite was studied by using two collectors,either in single addition respectively or in the mixture of the two . The research results show that the flotation index using composite collector were superior to that single collector . The results indicate that collector composed of SHA and P86 is suitable for the flotation of cassiterite ; the other composite collectors are not suitable for the flotation of cassiterite .By means of the measurements of zeta-potential and infrared adsorption spectrum . the interaction mechanism of composite collectors with cassiterite was studied . Among SHA adsorption on cassiterite surface , chemical adsorption occupied first place and non-uniform physical adsorption come second . Combined use of collectors . SHA and other collectors are co-adsorption on the surface of cassiterite and help each other . It means that while SHA molecules forms monolayer -adsorption on the cassiterite ,other collectors insert it or cover it . forming inserted-coadsorption and laminated-coadsorption simultancously .In this paper, on basis of the research results of pure minerals flotation tests . The effects of Fe³⁺, Fe²⁺, Ca²⁺, Al³⁺ ions interruption cassiterite flotation were studied . The resons of Fe Fe³⁺, Fe²⁺, Ca²⁺, Al³⁺ions interruption cassiterite flotation were analied by theories.This research of collectors to fine eassiterite of Da Malu has achieved some results, and what the auther has done has some signifance in future long-term product.
