This is known as the flotation separation method, and produces a frothy layer of particles that can be skimmed to provide the extracted platinum.
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
Opinions differ considerably when discussing the ease or difficulty of polishing platinum, but most agree that when a piece is well polished it tends to stay that way.

One suitable method for purification for the raw platinum, which contains platinum, gold, and the other platinum-group metals, is to process it with aqua regia, in which palladium, gold and platinum are dissolved, whereas osmium, iridium, ruthenium and rhodium stay unreacted.
Platinum Refining Process is described below. Platinum refineries provide an economical and environmentally friendly precious metal recovery service. We buy platinum scrap and separate the pure platinum from other precious metals and waste materials. Platinum scrap such as platinum coins, palladium PD and platinum wire is weighed and then smelted.
A wide variety of raw platinum options are available to you, such as free samples, paid samples. There are 2,327 raw platinum suppliers, mainly located in Asia. The top supplying countries are China (Mainland), India, and Vietnam, which supply 96%, 2%, and 1% of raw platinum respectively.
The ratio, in terms of availability, of platinum to gold is 1:15. This means that for every 15 gold there is only 1 platinum. It is also difficult to acquire a lot of it, as it will take 10 tons of raw platinum ore to come up with a single ounce of pure platinum. Aside from its rarity, platinum …
These are all extracted during the mining process. Because of the rarity of pgm and its tendency to combine with other metals, the mining process often yields far more nickel or copper than it does platinum. In South Africa, the world's largest producer, platinum is mined in an area called the Bushveld Igneous Complex.

Platinum jewelry is rare, beautiful, and durable, and is therefore highly regarded. Native Platinum is the most significant source of the element platinum, although considerable quantities are also mined from the rare platinum arsenide mineral Sperrylite. The rare metals iridium, osmium, rhodium, and palladium are almost exclusively mined ...
Platinum mining on a large scale began around 1926, and before the 1920s were over, no less than seven mining operations had started in South Africa. The platinum ores were mostly processed by traditional milling and gravity-table concentration.
