UG2 ore is the second most mined source of PGE in the Bushveld Complex. Loed in a reef close to and largely parallel to the historicallymined Merensky Reef, UG2 has always been an enticing source of PGE, but metallurgical difficulties delayed its extraction and processing until relatively recently. UG2 MineralOGY hOst MineralOGY UG2 ore contains two dominant suites of mineralisation ...

· The mineral beneficiation involves separation of gangue minerals from ore. It has three steps Liberation, Separation, Concentration. 1) Liberation of valuable mineral by size reduction. 2) Separation of coarse and fine particles. 3) Concentration to .
· 1. 1 BASICS OF MINERAL PROCESSING (Ore dressing Operations) by Prof. A. Balasubramanian Centre for Advanced Studies in Earth Science University of Mysore India 2. 2 Treatment of ores to concentrate their valuable constituents (minerals) into products (concentrate) of smaller bulk, and simultaneously to collect the worthless material (gangue) into discardable waste .
The concentration of the crushed ore is done mainly by the following methods: 1. Hydraulic (Gravity Separation) method: Principle: The difference in the density or specific gravity of the ore and gangue is the main principle behind this method. Oxide ores are purified by this method. Example: Haematite (Fe_2O_3) the iron ore. Important! Note: Hydraulic method is used when the ore is heavier ...
· Ores and Minerals Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material.

Problem: The iron content in ores can be determined by titrating a sample with a solution of potassium permanganate. The ore is first dissolved in hydrochloric acid, forming iron (II) ions, which react with permanganate ions according to the following netionic reaction: MnO4 (aq) + 5 Fe 2+ + 8H + (aq) → Mn 2+ (aq) + 5 Fe 3+ (aq) + 4 H 2O (l) A sample of ore of mass was dissolved in ...
New technologies in the concentration of PGM values from UG2 ores this technology. It is, however, a low capital and moderate operating cost option that they have used very effectively to bring the leader and main reefs into the concentrator at a reasonable head grade. This has contributed to making them one of the lowest cost producers. This type of technology is limited, however, to ...

· (i) Dressing of the ore is an essential process in the extraction of metal from its ore. Answer: The ores are found mixed with earthy impurities like sand, clay, lime stone etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing.
The dressing of ore is also called concentration of the ore because it gradually increases the percentage of metal. In metallurgy, the concentration of ore is achieved in the following two methods.
