·The metallurgical materials of platinum metals mainly include platinum metal concentrate and the secondary resources of platinum metals The former can be classified into three types gravity concentrate flotation concentrate of primary platinum ore flotation concentrate of copper sulfide and nickel ore in platinum metals
·Platinum Group Metals PGMs play a significant role in the manufacturing of catalysts super alloys electronics space materials biomedical equipments jewellery etc due to their excellent
The extraction technology for platinum group metals PGMs has changed dramatically in the last 80 years and the changes are likely to continue for years to come This article will review advances in PGM extraction including developments in semi autogenous and fully autogenous milling; flotation equipment applications for treating high chrome ores; increases in power
·The complexity of platinum processing arises from the presence of other platinum group metals PGMs that often coexist with platinum in the ore Value and Applications Platinum and gold have distinct values and applications Gold has been prized for its beauty and value for centuries and is predominantly used in jewelry and investment

·The major contributors to ore variability include hydrothermal alteration oxidation and weathering of a pristine ore deposit The alteration of sulphide minerals by oxidation can lead to reduced
The ore is processed by crushing and milling to reduce the coarse ore to fine particles liberating the sul phide containing platinum group metals PGM iron nickel and copper from the waste ore
