Refining of platinum group metals consists of several stages: I. Ore concentration by physical techniques such as flotation 2. I''vrometallurgical concentration producing coppernickel sulphide matte, and hydro metallurgical concentration 3. Final refining to produce the individual platinum group metals.
The platinumgroup elements (PGEs)—platinum, palladium, rhodium, ruthenium, iridium, and osmium—are metals that have similar physical and chemical properties and tend to occur together in nature. PGEs are indispensable to many industrial appliions but are mined in only a few places. The availability and accessibility of PGEs could be disrupted by economic, environmental, political, and
The Platinum Group Metals (PGM) are loed in the 5th and 6th rows of the transition metal section of the periodic table. Common characteristics include resistance to wear, oxidation, and corrosion, high melting points, and oxidation states of +2 to +4. They are generally nontoxic. For our
Dec 10, 2018 · The platinum group metals (PGMs) are six transitional metal elements that are chemically, physically, and anatomically similar. The PGMs are the densest known metal elements. Exceptionally rare, the six metals naturally occur in the same ore bodies. They are highly durable and, due to their high value, often recycled, giving them long life cycles.

Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverishwhite transition metal s name is derived from the Spanish term platino, meaning "little silver".. Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements has six naturally occurring isotopes.
A process for purifying and refining platinum group metals such as platinum, iridium, palladium, rhodium and the like by an electrochemical process using ammonium chloride as the electrolyte to form ammonium chloride platinum group salts as a "slime" followed by the use of ammonia hydroxide to dissolve and separate said salts from other materials in the slime.

Sulphide and flotation concentrates from 33 porphyry copper deposits have been investigated for platinumgroup elements (PGE), Au, Cu and platinumgroup minerals (PGM). The major sulphides in the samples studied are chalcopyrite and pyrite. Bornite is less frequent and molybdenite occurs in traces only. PGM (merenskyite, sperrylite and an unidentified PdSb telluride) have been found as

Aug 11, 2013 · Platinum Eagle Coin. Platinum group metals can be found in nickel and copper ores. The main ore mineral for platinum is the mineral sperrylite, which is a platinum arsenide and is associated with the nickel ores of the Sudbury Basin, Ontario, Canada. Platinum is also found as a native platinumiridium alloy and as the mineral cooperite, which
The platinum group consists of platinum, iridium, osmium, palladium, rhodium, and ruthenium. Amongst the alloys found in native state have been brass, bronze, pewter, German silver, osmiridium, electrum, white gold, and silvermercury and goldmercury amalgam. Only gold, silver, copper and the platinum metals occur in nature in large amounts.
From this stage onwards the concentration of the platinum group metals is more rapid and the processes entirely chemical. First the slime is subjected to roasting and leaching attacks to remove the last of the copper, nickel, iron and sulphur. This produces an enriched slime running approximately 65 per cent of the platinum group metals and gold.
