Abstract. extraction and separation of nickel and cobalt from saprolite laterite ore were studied by using a method of microwave-assisted hydrothermal leaching and chemical deposition. the usual method of nickel extraction from sulrde ores is through the production of nickel matte after enriching the nickel content of the ore. this is com- monly carried out by magnetic separation, sotation, or a combinationof both after the ore is comminuted to below 200 m in size. the enrichment depends upon the degree of rejection of the other sulrde and non-sulrde gangue. the maximum

Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. one of the most well-known purification processes is called the mond process, which is an extracting and purifying process developed by ludwig mond in 1899. 1. how is platinum extracted from its ore? an ore is a naturally occurring mineral from which a pure metal can be extracted. for platinum, the two- chief minerals are sperrylite or platinum arsenide (ptas2) and co-operate or platinum sulfide (pts). extracting platinum from these ores is arguably one of the most capital and labour intensive operations in the world. on average, it takes up to
