Comprehensive Utilization Status of Low Grade and Refractory Platinum-Palladium Ores from Jinbaoshan of Yunnan

It is difficult to handle platinum-palladium ores in Jinbaoshan due to low grade ores, kinds of mineral resources, complex mineral structure, fine-grained dissemination, which is a typical refractory complex ores. Based on the research of lots of correlative literature, this article analyses refractory reasons of platinum-palladium ores in Jinbaoshan, and provides an overview of comprehensive utilization status of low grade and refractory platinum-palladium ores on behalf of single flotation process, stage grinding-stage sorting and the combined process of flotation and magnetic separation, microwave pretreatment-leaching-replacement process, and the activation of acid leaching-extracting magnesium and iron-leaching residue to flotation process and so on.
