E Traction Of Platinum From The Pit

Extraction and Refining of the Platinum Metals

basic process for extraction of the platinum metals has remained essentially the same. Rustenburg converter matte contains about 46 per cent of nickel and 28 per cent copper, together with some other base metals and sulphur. The platinum group metals, together with some gold, total about fifty ounces to the ton. The complete process of extraction consists essentially of enriching this matte to

Extracting platinum metals Chemical Engineering Page 1

Platinum-group metals form a complex range of 30 to 40 minerals, each with a different resistance to leaching, making it difficult to find a unique solution for all deposits, explains Eksteen. Once leached, the metals are adsorbed from solution on to activated carbon, he says. The next step is to elute (wash with solvent) metals from the carbon in a concentrated form so they can be released

How Is Platinum Extracted? Reference

13/04/2020· Platinum ore can be obtained through controlled explosions or by advanced mining techniques. Once it has been mined, the platinum is extracted from the ore in the same way. The platinum ore is not pure, so it is first crushed. This produces many tiny particles that can be treated. Air particles then bubble through an aeration tank and adhere to the platinum particles. This brings the platinum

How is platinum extracted from its ore SlideShare

For Platinum, the two- chief minerals are sperrylite or platinum arsenide (PtAs2) and co-operate or platinum sulfide (Pts). Extracting Platinum from these ores is arguably one of the most capital and labour intensive operations in the world. On average, it takes up to six months and up to 12 tonnes of ore to produce an industry standard troy ounce, which is 31.135 grams of pure metal. However

An Overview of Platinum Great Mining

Vital amounts of platinum are manufactured from the mine sites in far eastern Russia and the Norilsk-Talnakh mine which is situated in the Polar ice cap using both open-pit strip and underground mining procedures. In Zimbabwe platinum was found in the year 1925 in a place by name the Great Dyke which runs approximately north and south for about 550 kilometers through the heart of the country.

How Is Platinum Extracted From a Catalytic Converter? It

The platinum, which appears as a silvery, bronze color located on the outer surface of each piece of catalyst, can be picked and peeled off by hand or by using a flat-head screwdriver or pair of box cutters. The platinum normally flakes off in small pieces or nuggets. As each piece is chipped off, it can be set aside and placed on a clean towel or rag. Complete platinum removal from the

OVERVIEW OF PGM PROCESSING Anglo American Platinum

Platinum Group Metals (PGMs) are recovered through underground and open pit mining from poly-metallic sulphide ores containing PGMs, Nickel, Copper and other metals: • Platinum (Pt), Palladium (Pd), Rhodium (Rh) and Ruthenium (Ru) are the most prevalent of the six PGMs, with Iridium (Ir), and Osmium (Os) found in much smaller quantities • Gold is often associated with PGM deposits and

Where does platinum come from?

While over 70 per cent of all mineral extraction global-ly arises from surface mining, in contrast, the geology and location of the world’s platinum reserves mean that platinum mining takes place principally under-ground. The main exception to this is Mogalakwena in South Africa which is the largest open-pit platinum mine in the world, producing some 8 per cent of annu-al platinum mine

How Is Platinum Mined History and Practices

In Russia, significant amounts of platinum have been produced from mine sites in far eastern Russia and the Norilsk-Talnakh mine located within the Polar ice cap, using both open-pit strip and underground mining methods. In 1925, platinum was discovered in Zimbabwe in an area called the Great Dyke, which runs roughly north and south for about 550 kilometers through the heart of the country

1. Open-pit mining. Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed

OPENCAST PLATINUM MINE PROJECT Miningreview

“Impala Platinum is an underground mining company and does not have the necessary expertise or the resources to undertake an opencast mining project, hence the decision to go the outsourcing route.” Concor Mining began work on the Impala opencast mining project in 2002 in the vicinity of Impala No. 6 shaft. “We mined the Merenksy ore body first and in 2005 we started mining the UG2

Grootegeluk Coal Mine Wikipedia

Exxaro was to invest R9 billion to speed up extraction from the existing pit, with delivery of coal to the first generation unit at Medupi to start in the 3rd quarter of 2011. Two new dense media coal beneficiation plants were to be built at the mine, and would be operating at full capacity by 2014. They would supply the Medupi generators with about 14.6 Mt of power station-grade coal annually
