在许多钨锡矿床中都共生有黄危鉍矿。黄铋矿是氧化矿物,性脆易于粉碎,比重与钨锡近似,应用重选方法时,富集于钨锡精矿中。在磨矿浮选时,据有的资料所载由于难以硫化故不易为黄药所捕收,很难用泡沫浮选收回。采用其它脂肪酸捕收时又缺乏选择性,同时选矿指标不高。若黄铋矿与硫化矿物及黑钨三者共生时,回收黄铋的方法一般是采用优先粒浮硫化矿后,用磁选,使钨矿作为磁选精矿而黄铋矿即作为尾矿残留富集回收。这个方法已经在一些厂矿中应用了。但是对于与
Hwang bismuth ore is symbiotic in many tungsten-tin deposits. Bismuthinite is an oxidized mineral, brittle and easy to crush, the proportion of similar tungsten and tin, the application of gravity method, enrichment in tungsten and tin concentrate. Flotation flotation, according to some information contained in difficult to sulfide it is not easy for xanthate collected, it is difficult to recover with the froth flotation. Selective use of other fatty acids while the lack of selectivity, while beneficiation index is not high. If the yellow bismuth and sulfide minerals and black tungsten symbiosis, the recovery of yellow bismuth is generally preferential pellet sulfide ore, with magnetic separation, the tungsten ore as a magnetic separation concentrate and bismuth ore that is as a tailings Residue enrichment recovery. This method has been applied in some factories and mines. But for and
