电选方法在国外工业生产上获得了广泛的应用,主要用于锆英石、金红石、独居石、钛铁矿、钽铌铁矿、白钨、锡石和金刚石等的精选。在分选金红石、锆英石或锡石、白钨时,由于待选矿物的比重和磁化系数都很接近,因此不能用重选法或磁选法进行分离。若采用粒浮,不仅劳动条件差、工效低,而且分选效果不好。上述矿物中金红石与锡石是导电体,锆英石与白鹅是非导电体,采用电 Electro-election method has been widely used in foreign industrial production, mainly for the selection of zircon, rutile, monazite, ilmenite, tantalum-niobite, scheelite, cassiterite and diamond. In the sorting of rutile, zircon or cassiterite, scheelite, due to the proportion of minerals to be selected and the magnetization coefficient are very close, and therefore can not be separated by gravity or magnetic separation method. If the use of particle floating, not only poor working conditions, low efficiency, and the sorting effect is not good. The minerals in the rutile and cassiterite are conductive, zircon and white goose is non-conductive body, the use of electricity
