How Is Platinum Extracted? Reference
Because platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another This is known as the flotation separation method, and produces a frothy layer of particles that can be skimmed to provide the extracted platinum This process is necessary because platinum, even 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 each other, followed by final refiningExtraction and Refining of the Platinum Metals Johnson About 80% of the worlds’ reserves for platinum group metals (PGMs) are in South Africa’s Bushveld Igneous Complex Processing of PGM involves comminution, flotation, smelting, converting, base metals refinery and precious metals refineryExtraction of Platinum Group Metals IntechOpenextraction 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 each other, followed by final refining Operations to Extraction and Refining of the Platinum Metals Extracting platinum from ore is both capital and laborintensive It can take up to 6 months and 7 to 12 tons of ore to produce one troy ounce (31135g) of pure platinum The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'The Properties and Applications of Platinum
Platinum Mining and Refining Education
The solution is filtered, purified, and burned to produce pure platinum metal Molten matte containing palladium and platinum is emptied from the furnaces at the Stillwater mine in North America The majority of world’s supply of platinum comes from two key sources Platinum deposits are located in only a few areas of the world For every ten gold mines there is only a single platinum mine All the Platinum extraction, uses and environmental impacts A seminar presented to Tamil Nadu Agricultural University(PDF) " PLATINUM EXTRACTION AND PURIFICATION, USES AND Platinum group metals (PGMs) are a group of six elements, namely iridium (Ir), osmium (Os), platinum (Pt), palladium (Pd), rhodium (Rh) and ruthenium (Ru) [1, 2]PGMs together with gold and silver are classified as noble or precious metals because of their high corrosion and oxidation resistance [1, 2, 3]The world’s reserves of platinum group metals/elements are estimated at 100 million Extraction of Platinum Group Metals IntechOpenTo extract the mineralrich materials, miners pack explosives into holes drilled in the rock and blast it into smaller pieces The broken rock is then collected and transported to the surface for processing Platinum production in South Africa Photo by Johnson Matthey Refining platinum ore is a costly and laborious process It can take from eight weeks to six months to process a batch of ore Platinum Mining and Refining Education Platinum is always found alongside other PGMs In South Africa's Bushveld complex and a limited number of other ore bodies, PGMs occur in sufficient quantities so as to make it economical to exclusively extract these metals; whereas, at Russia's Norilsk and Canada's Sudbury deposits platinum and other PGMs are extracted as byproducts of nickel and copperThe Properties and Applications of Platinum
