Flotation recovery of scheelite with combined collector
摘要
Abstract
The beneficiation experimental study is carried out according to the characteristics of a certain skarn type scheelite, in which the scheelite is finely and unevenly disseminated with the gangue minerals , such as fluorite, calcite and garnet, in the condition of granular, polyparticulate, star-dotted or impregnation. Based on analysis of the properties of the ore and the conditional experiments , three collectors are compared in the experiment including 731 oxidized paraffin soap , sodium oleate and combined collector LGW. As is shown in the results, combined collector LGW is better in collecting scheelite. Furthermore , comparative tests are conducted including heating concentration and normal cleaner , both using LGW. In heating concentration , scheelite concentrate with WO3 grade of 69.20 % and recovery of 78.30 % are obtained by treating rough concentrate obtained by closed-circuit consisting of one roughing , two concentrates and two scavengings. In normal cleaner, after pretreated by magnetic field and a long-time agitation , concentrate with WO3 grade of 59.00%and recovery of 79.60%is achieved with five regular cleaners.关键词
