chrome ore extraction and refining Extraction and Refining of the Platinum Metals extraction consists essentially of enriching this matte to approximately 65 per cent content of platinum metals and then treating this concentrate with acids to separate the individual platinum group metals from each other followed by final refining.
Extraction and refining. If carbon and Cr 2 O 3 are combined in a molar ratio of 3:1 and subjected to increasing temperature, a number of oxidation reduction reactions will ensue that will produce first a series of chromium carbides and finally, at 2,080 °C , pure chromium and carbon monoxide. (This will take place at 1 atmosphere, or about 100 kilopascals, of pressure, but reducing the pressure
