Characterizing and recovering the platinum group minerals––a review
Minerals Engineering, 2004Methods of characterizing and recovering the platinum group minerals are reviewed in this paper. First, a classification of platinum group minerals (PGMs) ore types is briefly introduced, followed by the introduction of some representative platinum group minerals.

Characterizing the behaviour of platinum group minerals in a grinding circuit
Minerals Engineering, 2021Abstract This paper introduces a methodology to determine the gravity-recoverable platinum group minerals (GRPGMs) of a stream, and behaviour of platinum group minerals (PGMs) in a ball mill-cyclone circuit. The GRPGM is determined by a modification of the method developed for gravity-recoverable gold (GRG).

Electrochemical interactions of platinum group minerals with copper sulphate
Minerals Engineering, 2017Abstract Activation of sulphide minerals by copper sulphate is common practice on platinum group mineral (PGM) concentrators. However, the role of copper sulphate in the flotation of PGMs is still unclear especially in the case of those PGM ores which contain relatively low concentrations of sulphides.

An electrochemical investigation of platinum group minerals
, 2015 The Bushveld complex is the largest ore body in the world hosting platinum group elements (PGEs). It is a stratified orebody with three major reefs namely, the Merensky reef, UG2 reef and the Platreef. Platinum and palladium are the most abundant PGEs found in the Bushveld complex. They occur in the form of minerals/mineral phases with elements such as

Platinum Group Elements Mineralization
2020Platinum group element (PGE) mineralization is associated with ultramafic and mafic rocks. There are three major types of PGE mineralization in Mongolia. The most common is (1) PGE mineralization related to ophiolites and includes podiform chromite, (2) PGE in layered gabbro intrusion, and (3) PGE-Au placer.

On the Management of Gangue Minerals in the Flotation of Platinum Group Minerals
Mining, Metallurgy & Exploration, 2018The Bushveld Complex of South Africa contains almost 90% of the world’s reserves of platinum group minerals (PGMs). In the flotation of PGMs, there are significant challenges arising from the need to treat ever-decreasing grades of the relevant ore deposits.

Biological role in the transformation of platinum-group mineral grains
Nature Geoscience, 2016Platinum-group elements are strategically important metals. Finding new deposits is becoming increasingly difficult owing to our limited understanding of the processes that affect their mobility in surface environments. Microorganisms have been shown to promote the mobility of metals around ore deposits.

Platinum-group minerals in Tasmania
Economic Geology, 1981Platinum-group minerals in Tasmania occur mostly in placer deposits and are composed mainly of iridosmine and rutheniridosmine. Platinum-rich alloys are rare. Silicate inclusions in the metals include olivine (Fo (sub 94-89) ), enstatite, and nonstoichiometric pyroxene rich in Ca, Mg, and Al.
