The Properties and Applications of Platinum

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'.Application of fundamentals in optimizing platinum,,The UG-2 ore is a platinum-bearing chromitite ore that contributes a growing proportion of the platinum group metal (PGM) production from the Bushveld Igneous,the ore.
