13.04.2020· 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 particles, with the air particles, up to the top of the tank. The layer of particles that ultimately
19.09.2014· 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, in mining using 4.5 tonnes of ore to produce one gram of platinum would not be considered abnormal. The extraction
Recovery of platinum-group metals from ores The United States of Metal values are recovered from ore concentrates by means of dry grinding, to extract platinum, palladium, copper and
2014-5-26africa primary smelting of ore concentrates is carried out in that region by five companies, namely anglo platinum, impala platinum, lonmin platinum, northam platinum, all of south africa, and makwiro platinum in zimbabwe the only other primary Copper mining and extraction sulfide ores
Extracting platinum from ore is both capital and labor-intensive. 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'. During flotation, air is pumped through the ore-water slurry.
As Platinum is so incredibly rare it can take about as much as 10 tonnes of ore to find one ounce of Platinum. There are several steps in the mining process of Platinum, the first one being extraction of the Platinum ore and bringing it above ground, there are two ways of doing this the first and older way is to blast the ore free with explosives.
A process for treating chromite-bearing ores to obtain useful mineral values, especially platinum group metal, therefrom wherein the ore is separated into magnetic and non-magnetic fractions; the...
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
Platinum Refineries, Johnson Matthey & Co Limited A major development in the world’s platinum industry took place in the early nineteen twenties when large deposits of platinum bearing ore were discovered in the Transvaal in South Africa. This led to the formation in

02.10.2017· In South Africa, the PGM ore is mined in the western and eastern limb of the Bushveld Igneous Complex .Within the Bushveld Igneous Complex, the Merensky reef, the Platreef and Upper Group 2 (UG2) reef are exploited for platinum production [1, 4, 9].Merensky and Platreef have similar chemical and mineral composition [6, 10].These reefs typically have fairly low contents of sulphides.
09.11.2020· The extraction process routes to recover high purity of platinum group elements are also reviewed. The classification briefly describes the different types of ore deposits. The mineralogical
Platinum ores such as sperrylite and cooperite may be mined when they are found in quantities that make extraction economically feasible. In other situations, platinum is obtained as a by-product when ores of other metals, such as copper and nickel, are refined. Modern Platinum Mining Techniques. Most of the mining for platinum ore occurs deep underground. To extract the mineral-rich materials
20.10.1981· Process for extraction of platinum group metals from chromite-bearing ore . United States Patent 4295881 . Abstract: A process for treating chromite-bearing ores to obtain useful mineral values, especially platinum group metal, therefrom wherein the ore is separated into magnetic and non-magnetic fractions; the non-magnetic fraction, containing a substantial portion of the platinum group
A process for extraction of platinum group metals (PGM) includes smelting PGM concentrate to provide PGM-containing matte, spinel-rich slag and oxide-rich slag. The matte is enriched with regard to PGM in a conversion step by selective oxidation of undesired constituents thereof. The process includes, after the smelting and prior to the conversion, separating the matte and the spinel-rich slag
