Earlier attempts to process the oxidized PGM ores by conventional flotation methods achieved poor recoveries (typically less than 50%). The resource estimates of oxidized PGM ores which are...
The complete process of extraction consists essentially of enriching this matte to approximately 65 per cent content of platinum metals and then treating this concentrate with acids to separate the individual platinum group metals from …
The concentrator treats platinum ore which is mined from the UG2 reef from various shafts in the Rustenburg area. Ores from these shafts are combined in receiving bins …
Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.
A breakthrough came in the 18 th century when a Swedish researcher added arsenic to the metal but it was only in 1782 that platinum was successfully melted by adding oxygen. After a further 25 years, it became possible to …
The third step is the extraction process. This is done by crushing the ore into minuscule pieces, once this is done the next process the platinum must proceed through is the flotation …
in general, pgm ores are concentrates in the crust found in two different ways, by leaching the metal-rich lava (mantle) deposited into the crust, which is known as chemical weathering, …
Earlier attempts to process the oxidized PGM ores by conventional flotation methods achieved poor recoveries (typically less than 50%). The resource estimates of oxidized PGM ores which are either unmined, mined, and stockpiled or discarded as overburden waste in South Africa and Zimbabwe are over 500 million tonnes.
As the platinum scrap liquefies in the furnace or melts under a blowtorch, flux is mixed in to separate the pure platinum from other precious and non-precious metals. A sample is removed for assaying, which is the process of measuring …
The Bushveld Igneous Complex (BIC) in northern South Africa has the largest deposit of platinum group elements (PGEs) in the world. In trace amounts, these are closely associated with base metal...
Basically, primary deposits of platinum ores are confronted in the folded and platform regions and these are always centered on big cracks in the earth's surface. The formation of these deposits lay hold of place at various depths, about 1/2–1 to 3–5 km, and in different geological eras, starting from the Precambrian to the Mesozoic epochs.
Fire assaying is a quantitative method of analysis amd determination for platinum group elements and gold in which impurities are separated metals by fusion. MORE ... ESSENTIAL FACTS Platinum is a beautiful silvery-white metal, when pure, and is malleable and ductile. The metal does not oxide in air.
Refining platinum ore is a costly and laborious process. It can take from eight weeks to six months to process a batch of ore, and it can take up to 12 tons (11 tonnes) of ore to produce a single troy ounce of platinum. Once the broken ore …
The concentrator treats platinum ore which is mined from the UG2 reef from various shafts in the Rustenburg area. Ores from these shafts are combined in receiving bins at the concentrator, or stored on common stockpiles if bins are full. Consequently, feed to the mill may vary from pure ores to blends of ores from the various shafts.

Most ore milling operations have work indices ranging from 10 to 12, with extremes between 8 and 22. Because most of the platinum-group bearing sulfides occurred as fine grains and required grinding to approximately 200 …
Initially, the ore is ground by crushing and ball milling in several stages or by SAG (semi-autogenous grinding) and then followed by smelting. The matte obtained undergoes hydrometallurgical treatment for removal of impurities such as Fe, Co, Ni and Cu leaving 10–50% of PGMs in the slime [ 13 ].
The samples come directly from plant and laboratory tests and are particles ranging in size from a few micrometres to few millimetres. The powder is cast in an epoxy block which is sectioned, ground and polished to a flat smooth finish. The polished samples are coated with a thin conductive layer of carbon.

For Platinum, the two-chief minerals are sperrylite or platinum arsenide (PtAs2) and co-operate or platinum sulfide (Pts). Extracting Platinum from these ores is arguably one of the most...
Extracting platinum from its ore is both capital and labor intensive. It can take up to 6 months and 7 to 12 tons of ore to produce 31.135g of pure platinum. STEPS INVOLVED : The first step in the production process is to break platinum …
The platinum-palladium mineralization was associated with the sulfides which made up about 1 pct of the rock. Microscopic examination of screened fractions of crushed ore showed that most of the sulfides could be …
