俄罗斯诺里尔斯克铜镍矿石中铂族金属品位与有色金属品位的比值随矿石类型不同而不同 ,硫化矿物含量少的矿石 ,其比值较高。过去公司的主要产品是有色金属 ,因此低硫化物矿石不当作能经济开采的矿石。由于近年来市场对铂族金属需求增长 ,开发利用这种矿石提到日程上来了。这种矿石平均含 9g/t铂族金属 ,采用重选 -浮选流程处理这种矿石 ,精矿铂族金属品位为 6 0 -70 g/t ,回收率为 75 -80 %。
The ratio of the PGM grade to the non-ferrous grade in Norilsk copper-nickel ores in Russia varies with the type of ore, with a higher ratio of ore with less sulfide minerals. In the past, the company’s main product was non-ferrous metals, so low-sulphide ores were not considered economically viable. Due to the increasing demand for platinum group metals in the market in recent years, the development and utilization of such ores have come to the agenda. This ore contains an average of 9 g / t of platinum group metals. The ore is treated by a re-election-flotation process. The concentrate has a platinum group metal grade of 60-70 g / t and a recovery of 75-80%.
