    • Extraction and Refining of the Platinum Metals

    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 the world whose prime activity is the extraction of the platinum metals. From the outset Johnson Matthey has been associated with Rustenburg, $rst in developing methods for the extraction of the platinum

    • (PDF) " PLATINUM EXTRACTION AND PURIFICATION,

    Platinum (Pt)Platinum (Pt) is a transition metal in Group 10 (VIIIB) of the periodic Platinum FactsThe annual supply of platinum is only about 130 tonswhich is equivalent to only 6% (by weight) of the total Western World's annual mine production of gold -and less than one percent of silver's yearly mine production.Approximately 10 tons of ore must be mined to produce one pure ounce of the "so-called white gold'' Total extraction process takes six long months All the platinum ever mined throughout history would fill a basement of less than 25 cubic feet Platinum Facts cont. Platinum is heavier than gold -one cubic foot weighs a little more than 603.2779 kg, about 11% denser than gold In Other words, a six-inch cube of the Platinum weighs about as much as an average man Platinum has many more industrial uses than either silver or gold In fact more than 50% of the yearly production of platinum is consumed by industrial uses -unlike gold Unlike gold, there are no large inventories of above-ground platinum.

    • How Is Platinum Extracted? - Reference

    2020-4-13  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.
