Platinum
Platinum-group metals are mined in South Africa (top producer), Russia, Zimbabwe, Canada, and the United States. Some platinum is obtained as a by-product of copper and nickel processing. Named from the Spanish word for silver, platinum is a lustrous, silvery-white metal that is very stable, being unaffected by air, water and most acids. It.

The major losses of Pt occur largely in mining (i.e. open pit or underground), accounting for about 27 – 28% before processing and the mineral concentration stages where 13 – 20% value loss occur to the tailings during flotation concentration (Ndlovu 2015). Value loss along the smelter and conversion stages is about ∼ 1%.
