Platinum and palladium ore beneficiation technology
Platinum and palladium ore beneficiation technology Platinum group (platinum, palladium, rhodium , iridium , ruthenium , osmium , gold , silver ) metals have excellent physicochemical properties, long-lasting stable service life and long-term storage value due to their special brilliant colors. Unique biological activity and catalytic activity have become an irreplaceable special metal widely used in various fields of human life. It can be said that there is no other kind of other metals or materials that, like precious metals, have superior dual functions in economics, finance, technology and industry. Platinum and palladium ore beneficiation technology The world's platinum ore resources can be divided into three categories: primary platinum ore; copper- nickel sulfided symbiotic ore associated with platinum group metals (not all nickel sulfide and copper ores associated with platinum group metals); After being discovered and developed by humans for 150 years, it has been exhausted. In the 1920s, primary platinum ore and symbiotic ore were discovered and mined, and the amount of platinum group metals produced from two kinds of resources has been about half each. It is estimated that the first half of the next century will remain the main source of human access to platinum group metals. Both types of resources contain 8 kinds of precious metals such as platinum, palladium, rhodium, ruthenium, osmium, iridium, gold and silver, and non-ferrous metals such as nickel, copper and cobalt . The comprehensive utilization value is large, and it is the only source of rare platinum group metals such as bismuth and antimony. The genesis of platinum-bearing deposits is very complex. After the mantle magma invades the crust, it undergoes different mineralization such as melting, differentiation and hydrothermal. Due to the influence of different regional geological environments, no large deposits can be found in the large-scale platinum-bearing deposits discovered so far. The features are exactly the same. Whether it is the size of the deposit, the type of ore, the enrichment law and location of the platinum group metal, the grade, proportion, mineral type, particle size distribution, symbiotic combination relationship and embedding characteristics of each precious metal and heavy non-ferrous metal, each deposit has its own Their respective characteristics. Humans have discovered and exploited native platinum ore for decades and have been researching and producing scientifically sound technical routes that have been proven by production. This is enough to prove the complexity of the development technology of platinum and palladium polymetallic symbiotic resources industry. In recent years, we have developed new beneficiation processes for platinum, palladium, rhodium, ruthenium, osmium, iridium, cobalt, copper and nickel, effective inhibitors of serpentine, effective collectors and activators for platinum and palladium minerals. The new process and new pharmacy in the development and utilization of the first primary platinum-palladium mine in China, broke through the years of exploration of the resource exploration and ore selectivity research, the size of the platinum group mineral is too small, must be finely selected. Binding, solved the problem of “poor, fine, miscellaneous†refractory platinum-palladium ore beneficiation. Concentrate obtained in the case of ore containing platinum + palladium = 3-4 g / ton, containing 0.14% copper and 0.175% nickel Platinum-containing palladium, 84.15 g / ton, platinum-palladium recovery rate of 84.50%; concentrate containing copper + nickel 7.32%, copper recovery rate of 92.88%, nickel recovery rate of 85.76%. The development and utilization of this resource industrialization has overcome the difficulties in mineral processing technology.
