Once the platinum-bearing ore is obtained, it undergoes a series of processes to extract the platinum minerals. This usually involves crushing and milling the ore to …
Results from test work from platinum ore on HPGR Test work has been conducted on two South African platinum ores. One being a Platreef ore, a sample of which consisted of pebbles from an AG circuit. The second one consisted of a UG2 ore obtained from a crushing plant feeding a rod and a ball mill. Both samples were treated on
The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the …
Abstract The beneficiation of platinum group metals (PGMs) from pristine (unweathered) sulfide ores has con-ventionally been conducted through froth flotation, which typically …

Feature papers represent the most advanced research with significant potential for high impact in the field. A Feature Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for future research directions and describes possible research applications.
In addition to platinum ore, the production of platinum requires a variety of chemical reagents and substantial energy inputs. Sulfuric acid, chlorine, and aqua regia (a mixture of hydrochloric and nitric acids) are among the chemicals used in refining platinum. ... The process also depends on sophisticated machinery for mining, crushing ...
Platinum group metals are conventionally recovered from high-grade concentrates (typically assay of 200 to over 2000 g/t PGM with 0.4–2.8% Cr 2 O 3) by the traditional matte–smelting–refining technique depicted in Fig. 2 (Cole and Joe Ferron, 2002).Ore is first ground by conventional multistage crushing and ball milling, or by …
Crushing rocks can be very dangerous, so put on protective gear. Wear thick work gloves to protect your hands from blisters and cuts, and use ear plugs to protect your hearing. Cover your eyes with safety glasses in case a piece of rock flies up into your face. Striking the rock can be very loud, so it might damage your hearing.

The impact-specific crushing energy has a significant impact on the particle size composition and crushing effect of the crushing product, and there is an interactive effect between the impact-specific crushing energy and the feed particle size and mineral type.
South African ores typically contain 3–4 g/tonne of PGM ore, which becomes 100–200 g/tonne after flotation. ... The ores are made into concentrate by crushing and grinding to particle sizes of about 80% and also by bulk flotation of sulfide minerals from the host rock. This chapter describes platinum-group ores and minerals and discusses ...
Platinum 2012 815 Figure 5-Pilot plant for DMS tests DMS application The application of DMS preconcentration, and its success, is very site- and ore-specific.
