Paenibacillus polymyxa菌细胞以及它们的代谢产物,例如蛋白质和胞外多糖,可以用来有效地分选黄铜矿中的方铅矿。黄铜矿和方铅矿与生物细胞作用后发生明显的絮凝,而使用生物蛋白质处理则只引起黄铜矿的选择性絮凝,使方铅矿分散。经过细胞、生物蛋白质或胞外多糖处理后,生物诱导选择性絮凝可以实现黄铜矿与方铅矿混合物的有效分离。采用生物蛋白质优先处理将强化方铅矿从黄铜矿中的浮选。论证了细菌细胞和生物试剂,例如蛋白质和多糖,在矿物加工中的作用。
Paenibacillus polymyxa cells and their metabolites, such as proteins and exopolysaccharides, can be used to efficiently classify galena in chalcopyrite. Chalcopyrite and galena with biological cells after significant flocculation occurs, while the use of biological protein treatment is only caused by the selective flocculation of chalcopyrite, gypsum dispersed. Bio-induced selective flocculation allows efficient separation of the chalcopyrite from the galena mixture after treatment with cells, biological proteins or exopolysaccharides. The use of biological protein preferential treatment will strengthen the flotation of galena from chalcopyrite. The role of bacterial cells and biological agents, such as proteins and polysaccharides, in mineral processing is demonstrated.
