platinum beneficiation used

The beneficiation studies of Suresh (1981) illustrate that low-grade chromite ore of 16%–25% Cr 2 O 3 of Sitampundi area of India, cannot be upgraded by using conventional physical beneficiation techniques like gravity and flotation, due to the intimate association of iron in the lattice of chromite particle. However, they have demonstrated ...

Beneficiation entails the transformation of a mineral (or a combination of minerals) to a higher value product, which can either be consumed locally or exported. The term is used interchangeably with "value-addition". Downstream value addition involves a range of activities including large-scale capital-

This has increasingly led to calls for beneficiation and value addition. The country is home to the world's second largest platinum group metals (PGMs) and chrome deposits after South Africa. It has a high gold yield per square kilometre, huge deposits of iron ore, nickel, copper, lithium and possibly oil and gas.

May 17, 2017. THE Zimbabwean cabinet has today agreed to a proposal by South Africa's Pallinghurst Resources and the Industrial Development Corporation (IDC) that will lead to $500m in beneficiation investment which, at a single stroke, resolves more than a decade of regulatory uncertainty for foreign platinum miners operating in the country.

J. Engelbrecht. Multotec (Pty) Ltd. Abstract. Understanding the deportment of minerals in size fractions has already led to improvements in the flow sheets for platinum minerals beneficiation. There are, however, more potential changes in the flow sheets that may improve the recovery of platinum group metals or reduce the costs of beneficiation ...

ABSTRACT Platinum group elements have become imperative to many modern industrial applications (automobiles, jewelry, pharmaceuticals, electronics, fuel cells, etc.) but are mined in only a few places. Characterization followed by beneficiation and extraction of these elements has many challenges for the applied mineralogist and …
