platinum ore processes

Extraction and Refining of the Platinum Metals

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

Recovery of platinum group metals from oxide ores—TML

The Great Dyke, Zimbabwe, contains over 800 million ounces of platinum and approximately 20 million ounces of rhodium. However, about 10% of the ore is oxidized and cannot be processed with current recovery methods. A conventional flotation-smelting process has been proposed to recover the platinum group metal (PGM) values from the sulfide ores.

2020-9-1 · Platinum-group elements (PGE: Ru, Rh, Pd, Os, Ir and Pt) are present in extremely low concentrations (0.000022–0.00052 ppm; Rudnick and Gao, 2003) in the upper continental crust. In ore deposits, concentrations occur in the range of 1 to 15 ppm. The majority of PGE is mined from the Bushveld Complex in South Africa.

The Properties and Applications of Platinum

2020-8-21 · 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'.
