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 …

The achieved successes of PGM concentration by flotation from the pristine sulfide ores are largely due to the occurrence …
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 ...

This chapter describes the production of concentrates containing the platinum-group metals (PGMs). South Africa is the largest primary producer of PGMs followed by Russia. South African ores typically contain 3–4 g/tonne of PGM ore, which becomes 100–200 g/tonne after flotation. There are two main types of ores namely; feldspathic ...

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 ...
Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may …
> Mining and mineral beneficiation plays a pivotal part in South Africa's economy. The country's mineral reserves are among the most valuable in the world. > South Africa has the world's largest reserves of platinum group metals (PGMs) and manganese, and some of the largest gold, diamonds, chromite ore and vanadium deposits.
2. Geology. In South Africa, the PGM ore is mined in the western and eastern limb of the Bushveld Igneous Complex [].Within the Bushveld Igneous Complex, the Merensky reef, the Platreef and Upper …
2.4. Beneficiation methods. Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.

It is an excellent conductor of electricity and has catalytic properties, making it useful in various chemical reactions. Uses of Platinum: Catalytic converters: Platinum is used as a catalyst in …
Abstract. Supply of world chromite (chrome ore) has come under severe pressure over the past year driven by strong demand for ferrochrome used in ferroalloy production for making stainless steel. Many of the strategic minerals are inputs into products in fast-changing markets. This article reviews the major process flow sheets in practice …
ABSTRACT The beneficiation of platinum ore in South Africa is based on removal and isolation of impurities, however, the design of processing plants deals mostly with the major constituents of these impurities. There has not been enough attention given to comprehensively deal with trace impurities characteristic of Bushveld Complex ore body ...
Characterization followed by beneficiation and extraction of these elements has many challenges for the applied mineralogist and mineral engineers due to its ultratrace concentration (2–4 ppm ...
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 …

SA accounted for 1% of total global exploration expenditure (14% for Canada & Australia, 13% for the rest of Africa). Top three mineral sales - coal, platinum group ...
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.
The emergence of a symbiotic relationship with the platinum-group metals industry was identified as a major development, with chromite ore intensity decreasing from 2.54 to 1.98 kg per kg ferrochrome.
