The valorisation of platinum group metals from flotation tailings: A
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%.
