Does Platinum occur with Gold ore?
Yes- typically platinum, gold, and palladium are found in the same ore.
How is platinum extracted from its ore?
Platinum is rarely found on its own, but in combination with other base and precious metals. Extraction of the pure metal from ores is a complex process, and includes milling the ore, a froth floatation process, and smelting at high temperatures. This removes base metals, notably iron and sulfur, and concentrates PGM- platinum group metals- gold, platinum and palladium. The PGM matte is further processed by electrolysis to remove nickel, copper and cobalt. The high grade concentrate is treated by solvent extraction, distilling, and ion exchange treatment to separate the PGMs into its separate metals.
How is platinum mined?
Ore leaves the mine to be refined.The first step in the mining process is getting the platinum ore out of the ground and into a refinery or processing plant. Two methods exist to extract platinum ore: the old "narrow reef method" and newer mechanical mining methods. The original "narrow reef method" consists of drilling holes, loading them with explosives and removing the ore once it's blasted free.Newer methods utilize specialized drilling equipment to remove the ore and load-haul-dump machines to transport the ore from the mine. Platinum may be mined using traditional open-pit strip-mining methods or underground mining methods, depending on where the vein is located.Extracting pgm from the rest.Once it's mined, the extraction process begins. The platinum ore is first crushed to produce tiny particles suitable for further treatment. The next step is the flotation separation method, which relies on air particles bubbling through an aeration tank to adhere to pgm particles and float them to the top of the tank. They form a froth at the top of the tank, which is then skimmed off for refining.Concentrating pgm.The concentration process requires smelting the dried pgm froth at high temperatures to separate the pgm further from unwanted materials. Other minerals oxidize and are removed. The pgm is then treated with air to blow out particles of iron and sulfur in order to further concentrate the platinum group metals.Refining platinum.After mining, extraction and concentration, platinum group metals must be refined. This is another step that removes nickel, copper and cobalt from the other pgm. Electrolytic techniques remove the copper, cobalt and nickel from platinum group metals. Finally, a series of ion-exchange techniques, distillation and solvent extraction occur. Soluble metals, such as gold, are dissolved in hydrochloric acid and chlorine gas, and finally only platinum remains.
What is the difference between gold ore and iron ore. Why can we see small pieces of yellow metal in gold ore but no iron metal in iron ore?
gold is very resistant to corrosion so a significant fraction of gold ore is pure gold metal. iron corrodes very easily so iron ore is always mostly a mix of iron oxides (i.e. rusts).
What is the difference between gold ore and gold nuggets?
Gold nuggets are as small as gravel or sand grains, while gold ore is large and is a group of minerals.
Does Platinum occur with Gold ore?
Yes- typically platinum, gold, and palladium are found in the same ore.
Where was palladium discovered in?
William Wollaston discovered in 1803 palladium in a platinum ore from South America.
How was palladium discovered?
A man that goes by the name William Hyde Wallaston discovered palladium in 1803 accidentally by analyzing samples of platinum ore.

Hpw is the ore platinum refined?
Platinum ore is refined in one of two ways. The first is individual solubilization and the second is simultaneous solubilization.
What type of rock is platinum?
its not a rock its an ore
How is the element Osmium obtained?
It is obtained from ore of platinum.

Why is platinum found as a metal not an ore?
like gold it does not corrode easily.
What does raw platinum look like and who can you call to find out if it is platinum?
A1. Platinum can occur in many forms in nature. The platinum group elements (platinum, palladium, rhodium, ruthenium, iridium, osmium) generally occur as alloys with iron or with transition group metals such as arsenic, tellurium, antimony, and vanadium; or as mixed platinum-palladium sulphide minerals (cooperite and braggite).They are typically associated with copper and nickel sulphide mineralisation (commonly chalcopyrite, pyrrhotite, pentlandite) and/or with chromite. Known occurrences of platinum in its native metallic form are restricted to a handful of locations, including the Urals mountains and the Kamchatka Peninsula in Russia, and the Tulameen district of British Columbia, Canada.A2. Platinum metal is metallic silvery-grey.There is a picture of platinum-bearing ore on the front page of the "Platinum 2002 Interim Review "http://www.platinum.matthey.com/publications/pgm-market-reviews/archive/platinum-2002-interim-review/ There is also a picture of Russian platinum nuggets on page 20 of 'PGM Mining in Russia' in "Platinum 2004 " http://www.platinum.matthey.com/uploaded_files/Pt2004/PGM%20Mining%20Russia.pdfhttp://chemistry.about.com/od/imagesclipartstructures/ig/Science-Pictures/Platinum-Group-Metal-Ore.htm
Why is the price of palladium so high?
Palladium, along with platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). PGMs share similar chemical properties, but palladium is unique in that it has the lowest melting point and is the least dense of these precious metals. Incredibly, when palladium is at room temperature and atmospheric pressure, it can absorb up to 900 times its own volume of hydrogen, which makes palladium an efficient and safe storage medium for hydrogen and hydrogen isotopes. Palladium is also tarnish resistant, electrically stable and resistant to chemical erosion as well as intense heat. The unique properties of palladium and other PGMs account for their widespread use. One in four goods manufactured today either contain PGMs or had PGMs play a key role during their manufacturing process. Over half of the supply of palladium and its sister metal platinum goes into catalytic converters, which convert up to 90% of harmful gases from auto exhaust (hydrocarbons, carbon monoxide and nitrogen oxide) into less harmful substances (nitrogen, carbon dioxide and water vapor). Palladium’s precious metal qualities and appearance generate significant consumption in the luxury jewelry market. Palladium is found in many electronics including computers, mobile phones, multi-layer ceramic capacitors, component plating, low voltage electrical contacts, and SED/OLED/LCD televisions. Palladium is also used in dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment, and it plays a key role in the technology used for fuel cells, which combines hydrogen and oxygen to produce electricity, heat and water. Palladium bullion has ISO currency codes of XPD and 964. Palladium is one of only four metals to have such codes, the others being gold, silver and platinum. Ore deposits of palladium and other PGMs are rare, and the most extensive deposits have been found in the norite belt of the Bushveld Igneous Complex in the Transvaal in South Africa, the Stillwater Complex in Montana, USA, the Sudbury District of Ontario, Canada, and the Norilsk Complex in Russia. In addition to mining, recycling is also a source of palladium, mostly from scrapped catalytic converters. The numerous applications and limited supply sources of palladium result in palladium drawing considerable investment interest.
