Distribution of PGE and PGM in Oxidized Ores of the Main ...

Distribution of PGE and PGM in Oxidized Ores of the Main Sulfide Zone of the Great Dyke, Zimbabwe ... pristine MSZ ores were 86% and 90%, respectively, at Hartley mine, and are slightly lower at Mimosa mine. Prendergast (1990) stated that all early attempts of processing oxidized MSZ ores resulted in Pt recoveries below 50% by either gravity ...

Platinum Group Metals | Chem230 Wiki | Fandom

PGM dominant deposit, as name suggests, is primarily composed of PGM with nickel and copper as less valuable byproduct. Nickel-copper sulphide, on the other hand, is sulphide-rich ores and PGM is considered byproduct. Platinum Group Metal Mining and Refining Process. PGM ores are …

Leaching and recovery of platinum group metals from UG-2 ...

Existing processes for the recovery of platinum group metals (PGM) from UG-2 ores place stringent requirements with regard to chromite content upon feed material to the plant. An alternative hydrometallurgical process for which this is not an issue is proposed that involves reductive roasting of the ore followed by leaching with

How to Extract Precious Metals From Sulfides | Sciencing

Cadmium, cobalt, copper, lead, molybdenum, nickel, silver, zinc, and gold and platinum group metals can be found in sulfide forms. These concentrated ore deposits are considered low grade because of the economic costs associated with processing, but they can be separated economically when prices for these metals rise on the open market.

Recovery of platinum group metals from oxide ores—TML Process

A conventional flotation-smelting process has been proposed to recover the platinum group metal (PGM) values from the sulfide ores. With the development of a low temperature roasting, acidic bromine leaching process by The Minerals Laboratory of BHP Minerals, substantial PGM recoveries from oxide and mixed oxide/sulfide ores are now possible.

The Properties and Applications of Platinum

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. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.

Platinum group - Wikipedia

The platinum-group metals (abbreviated as the PGMs; alternatively, the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs)) are six noble, precious metallic elements clustered together in the periodic table.These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6).

Copper anodes from the converter process are dissolved electrolytically using an acid copper sulphate solution as an electrolyte. The products of this operation are pure copper cathodes and an anode slime which may contain gold and small quantities of the platinum group metals. The cells are constructed of rubber-lined concrete.

Production - South Africa - PMM

Mill-head grades of BIC ore (a measure of the ore's pgm content as it enters the first stage of processing) are typically between 2 and 6 grams of combined platinum, palladium, rhodium and gold per tonne. Allowing for losses which occur during refining, and the varying platinum contents of the different Bushveld ores, this means that between 10 ...

Platinum is produced in South Africa by Amplats, Impala ...

South Africa has more than 80 per cent of the world's platinum reserves, and is the world's largest producer of platinum group metals (PGMs). These vast resources occur together with the world's largest reserves of chromium and vanadium ore in the unique Bushveld Complex geological formation.

Ore processing by PGM concentration process and assessment ...

Life cycle assessment analysis of ore-concentration was developed and equivalent carbon dioxide emissions quantified. One tonne of Ore-based PGM Concentrates, a total amount of equivalent carbon dioxide of about 1.574,96 kg CO2-eq was associated with this process.
