A solid platinum nugget. Image from popsci . Nuggets or grains of pure platinum can be found in nature, but more frequently, platinum is found alloyed with other metals, such as iron, copper, gold, nickel, and the other PGMs.The size of platinum grains or nuggets varies from small granules to pebbles weighing up to 20 pounds (9 kg) or more.
Abstract. Gold is typically associated with platinum group metal (PGM) ores and is ultimately recovered in the precious metals refineries. This chapter summarizes the extraction and refining of gold from PGM-bearing concentrates and secondary materials. Pyrometallurgical and hydrometallurgical methods are both used in the industry, spanning ...
Platinum-group metals are found mainly in South Africa and Russia, and are mostly also produced in those countries. Extraction of platinum-group metals consists of the following steps: Mining, concentration, smelting/converting, leaching and refining to metal. About 500 tonnes of platinum-group metals are produced per year. get price
