How Is Platinum Mined: Originally pgm was extracted using “the narrow reef method” in which miners use handheld pneumatic drills to create holes in the reef into which explosives can be loaded. After the ore is released through blasting, it is removed using scrapers attached to wenches and transported to . Mining platinum in placer deposits is a relatively simple process. Dredges scoop the platinum-bearing sand or gravel from riverbeds or mining pits. The material is washed until platinum grains or nuggets are captured and pulled from the surrounding material. Sperrylite, or platinum heathmagic.deted Reading Time: 7 mins.  · 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 heathmagic.deted Reading Time: 1 min. How is platinum mined and extracted?. Platinum’s rarity means that open-pit mining is fairly unusual. Underground mining is much more common, with techniques such as ‘narrow vein stoping’ being employed by many companies. Platinum deposits are often found in long, thin ‘reefs’. The mine walls are drilled and explosives are placed inside.

Nuggets or grains of pure platinum can be found in nature, but more frequently, platinum is found alloyed with other metals, such as iron, copper, gold, nickel, and the other PGMs. The size of platinum grains or nuggets varies from small granules to pebbles weighing up to 20 pounds 9 kg or more.

When platinum is found in a pure state, it is called native platinum. The Ural Mountains are well known for their rich mineral deposits. Over the last few centuries mining has varied from small-scale family operations to large mining conglomerates. In contrast to gold, platinum nuggets are relatively inconspicuous. They have a dull grayish or blackish color but when you handle them, they can be distinguished by their extraordinary heft. When iron is present in the alloy, a platinum nugget can also be slightly magnetic, a diagnostic tool for evaluating new discoveries.

Platinum is considered a biologically compatible metal because it is non-toxic and stable, so it does not react with or negatively affect body tissues. Although platinum most often naturally occurs in placer deposits, platinum and Platinum is present in thin sulfide layers in certain mafic igneous bodies and is mined in Canada, Russia, South Africa, the USA, Zimbabwe and Australia. Below is a list of some of the many other applications for platinum: Start planning your entries now!

South Africa, with vast platinum ore deposits in the Merensky Reef of the Bushveld complex, is the world’s largest producer of platinum, followed by Russia. Demand from the medical industry is growing as platinum can be used for both its conductive properties in pacemakers‘ electrodes, as well as aural and retinal implants, and for its anti-cancer properties in drugs e. For Platinum, the two- chief minerals are sperrylite or platinum arsenide PtAs2 and co-operate or platinum sulfide Pts.

Platinum is also used to catalyze nitric acid and gasoline; increasing the octane levels in fuel. Aqua regia a concoction of nitric acid and hydrochloric acid is used to dissolve platinum metal from the mineral concentrate by creating chlorine that attaches to platinum to form chloroplatinic acid. During flotation, air is pumped through the ore-water slurry. In , Englishman William Wollaston discovered a method for effectively extracting the metal from ore, which is very similar to the process used today.

Most platinum ever mined is currently in use in some form or fashion. Catalysts speed up chemical reactions without themselves being chemically altered in the process.

Connect and share knowledge within a single location that is structured and easy to search. In this blog explaining how money works as a response to the debate about the USA’s proposal to mint a trillion dollar platinum coin, the author quotes two estimates. One is the amount of platinum ever mined; the other is the amount required to make a trillion dollars if the value equalled the current price of platinum.

The author is making the point that money’s value isn’t intrinsic via an comic, exaggerated metaphor. But his estimate of world platinum production feels ridiculously low at 16 tonnes this would fit into a cube less that 1 meter about 3 feet on each side. So is his estimate even approximately right? How much platinum have we mined since the element was discovered about years ago? Your question mentions both words. No the world didn’t produce 16 tons of platinum, but much more.

See below for details. BTW, the „16 ton“ figure you cited was from that blog’s copy of ZeroHedge’s graph , and the graph had „16 tons“ as “ All Platinum ever MINED „, not „minted“.

This platinum precious metal guide explains the value behind platinum and what the metal is primarily used for in commercial industries. Interested in how platinum is traded? See our full guide , or if you want to get started trading right now, here are options available in to consider:. Disclaimer: Availability subject to regulations. Between The greyish-white metal is one of the most intriguing commodities because its user base defies simple categorization.

Business sectors such as the automotive industry demand platinum for use in catalytic converters, while investors covet the metal as a financial asset and store of value. Most of the industrial applications for platinum were developed after the s when air quality laws required catalytic converters on automobiles. However, by some measurements, platinum is even rarer than gold.

Miners extract only about million tons of platinum from the ground annually compared to more than 1, tons of gold. Platinum mining is also far less efficient than gold mining. The process of extracting the metal from ores can take five to seven months and may require ten tons of ore to yield one ounce of platinum.

Although silver is relatively scarce, it is the most plentiful and least expensive of the precious metals. Silver market surplus and deficits. Silver is rarely found in its pure form, called native silver. The largest silver nugget ever found weighed a whopping 2, pounds troy and was discovered in Mexico. More commonly, silver is found in mineral ores such as argentite, cerargyrite, stephanite, and chlorargyrite.

Silver sources during the s. Even these ores are found in small quantities, and many tons of material must be mined to produce just a few ounces of silver. Primary and secondary sources of silver ore. There are approximately open pit and underground silver mines in the world today.

By NS Energy Staff Writer 04 Oct Platinum is a precious metal that is part of the six-member family of platinum group metals.

Palladium, rhodium, iridium, osmium, and ruthenium are the other members of the group. Part of the platinum group metals, the precious metal is widely used across automotive, medical and electronics industries, along with jewellery production and as an investment in the form of coins and bars. Platinum is usually found alongside other metals, notably palladium and rhodium, in addition to base metals such as copper, nickel , and chrome.

As the metal is rarely found in isolation, a complex series of physical and chemical processes are employed for its extraction, processing and purification. However, saw a decline in platinum production compared with the mt in , due to several factors such as low prices for the metal in the market, workforce reduction, and mine-shaft closures.

NS Energy profiles the five biggest platinum producing countries based on their production in Owing to various factors such as job losses and mine-shaft closures, the country witnessed a sharp fall in production last year compared to the mt recovered in In August , Impala Platinum , one of the leading platinum miners in the world, announced plans to close five shafts at the Impala Rustenburg mine.
