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%.

Mineral Processing. Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. In the early years, mineral processing was called mineral concentration or …
11:46 am. Mineral processing is a key activity in the mining world, focusing on boosting the worth of raw minerals pulled from the earth. This crucial step turns the dug-up ores into cleaner and more concentrated versions that are ready for more use. By using both physical and chemical methods, mineral processing separates good, useful …
