Note: If the platinum is alloyed with silver and the platinum content is 25% or less, separation and recovery of the platinum is a difficult and sometimes impossible task (this is due to a series of not well understood chemical reactions that take place in the refining process).
Platinum (Pt) is a rare and valuable metal that is widely used in various industrial applications due to its unique properties. Platinum ore refers to the naturally occurring rocks or minerals that contain significant concentrations of platinum, usually in the form of platinum group minerals (PGMs) and associated minerals. Platinum ore is typically found in specific geological …
The beginning of the refining is the done using the concentration process, the dried platinum froth is then smelted at incredibly high temperatures, then treated with air. After this occurs the Platinum is refined to remove any other particles or metals until it is only Platinum which remains.
