Jul 13, 2020· New platinum extraction method to aid Kimberley projects. Monday, July 13th, 2020. The Kimberley region of Western Australia could be rife with platinum resources that are yet to be developed by Panoramic Resources, according to a study that is supported by the state government.

A major development in the world's platinum industry took place in the early nineteen twenties when large deposits of platinum bearing ore were discovered in the Transvaal in South Africa. This led to the formation in 1931 of Rustenburg Platinum Mines Limited to work these deposits, and this company remains to this day the only platinum producer in South Africa and the only major producer in ...

Apr 03, 2002· Platinum (Pt), a very rare substance, is very less abundant than gold. It exists in very few commercially viable deposits on earth. Most of the platinum mining is carried out in three leading producing regions in South Africa, Russia, and North America.

The extraction process routes to recover high purity of platinum group elements are also reviewed. The classification briefly describes the different types of ore deposits.

Aug 21, 2020· Extracting platinum from ore is both capital and labor-intensive. It can take up to 6 months and 7 to 12 tons of ore to produce one troy ounce (31.135g) of pure platinum. The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'.

Apr 13, 2020· Because platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another. This is known as the flotation separation method, and produces a frothy layer of particles that can be skimmed to provide the extracted platinum.
