Most platinum minerals are associated with the copper sulfides and palladium with the nickel sulfides. The ore also contains less than 1% quartz but significant amounts of talc and serpentine (MgO). Platinum was long known to exist in the arsenide form (sperrylite, PtAs 2) in nickel–copper sulfides in the Sudbury area.

Coal beneficiation involves water-intensive processes to remove impurities, necessitating careful water management strategies. Iron Ore Mining. Iron ore mining in South Africa is characterized by extracting hematite and magnetite ores, which are processed through water-intensive methods such as beneficiation and pelletization.
In many lithium ore beneficiation plants, it is a common practice to de-slime the ore prior to flotation. De-sliming is typically carried out to remove the −20 µm size fraction to improve selectivity of separation because slimes are detrimental to the flotation circuit (Bale and May, 1989). As is the case in many operations, de-sliming is ...
ores contain platinum, palladium, rhodium, gold, ruthenium, iridium and osmium (the PGMs), as well as nickel, copper, and cobalt in economically re-coverable quantities. Three broad ore types are found within the BIC and exploited for their PGM values: the Merensky reef, the UG2 reef, and the Plat reef. The first two reefs are
Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is …

The Aqueous Geochemistry of the Platinum-Group Elements with Applications to Ore Deposits (Wood) pulls together much heretofore scattered data and applies them to various types of deposits. This is also the only paper in the book where references to and discussions of porphyry copper, black shale, and seafloor massive sulfides can be found .
This chapter describes platinum-group ores and minerals and discusses how they are made into flotation concentrates enriched in platinum-group metals, different ores and their respective …
Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals. 1.3 Run-Of-Mine Material and Minerals. Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility.

This review critically discusses and gives an update on the classification and mineralogy of platinum group element ores around the world and also assesses the beneficiation practices and developed process flowsheets for recovery of platinum group element values.
Sylvania Platinum is a rapidly expanding low-cost PGMs producer listed on the London Stock Exchange's Alternative Investment Market ... First PGM beneficiation facility on primary chrome ore and tailings on the northern part of the Western Limb of the BIC. 50:50 JV with Limberg Chrome Mine (LMC) to recover chromite and PGM concentrates from run ...
A major development in the world's platinum industry took place in the early nineteen twenties when large deposits of platinum bearing ore were discovered in the Transvaal in South Africa. This led to the formation in 1931 of Rustenburg Platinum Mines Limited to work these deposits, and this company remains to this day the only platinum producer in South Africa and the only …
Ore processing is the process of separating valuable minerals from its ores by ore beneficiation equipment.
