本文综合历次对褐钇铌矿粗精矿精选研究结果,对褐钇铌矿及其伴生矿物的分离特性做了一些分析,并列举了不同组成的粗精矿的精选实例,说明以磁选为主结合重选、粒浮、电选的精选方法可以排出大量杂质,提高精矿质量,为冶炼提供优质精矿并获得了满意的回收率。一、褐钇铌矿矿物性质自然产出之褐钇铌矿多呈似晶体,但有一部分是结晶质的,正方晶系。颜色一般为
Based on the previous research results on the selection of the crude concentrate of the brown yttrium-niobium ore, some characteristics of the separation of the brown yttrium-niobite ore and its associated minerals are analyzed. Selected examples of crude concentrates with different compositions are cited, Selected as the main combination of re-election, particle floating, electricity election of the selected method can discharge a large number of impurities, improve the quality of concentrate, smelting provide high-quality concentrate and obtained satisfactory recovery. First, the brown yttrium niobium mineral nature of the natural output of the yttrium niobium ore mostly like crystals, but some are crystalline, tetragonal system. The color is generally
