在許多钨锡矿床中都共生有黄鉍矿。黄鉍矿是氧化矿物,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,据有的資料所載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。若黄鉍矿与硫化矿物及黑钨三者共生时,回收黄鉍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鉍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。但是对于与白钨、锡石共生的黄鉍矿,采用上述方法来进行分选是十分困难的,甚至是不可能的。用粒浮方法來回收这类矿砂中的泡鉍矿是一个值得引起注意的方法。
In many tungsten-tin deposits are symbiotic bismuth ore. 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, the use of 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. However, for the bismuth and cassiterite symbiosis of bismuthinite, the use of the above methods for sorting is very difficult, or even impossible. The recovery of bismuthinite from this type of ore by the levitation method is a noteworthy one.
