Prior to and/or during the flotation, a lead-containing activator reagent and a xanthate collector reagent are added to the slurry and during the flotation, an oxygen-deficient flotation gas, such as

24-06-2017· Because most of the platinum-group bearing sulfides occurred as fine grains and required grinding to approximately 200-mesh for liberation, flotation was investigated as a means for concentrating the metal values. The low concentration of metal values in the ore made it difficult to obtain consistent analytical results.

08-09-2018· Because of the presence of acid-consuming minerals in the ore, the flotation scheme devised for the anorthositic platinum-palladium ore was not satisfactory for the serpentinized ore. To obtain the desired pulp pH of 3.7 for acid circuit flotation, an excessive amount of sulfuric acid (92.5 lb per ton of ore) was required.

Cu & Pb can be floated around 7-7.5 pH but Zn requires slightly higher pH of 8-9 . Pyrite & Pyrhotite remains in the tails as non-float and can be recovered by cleaning in the acidic pH using Xanthate as the collector. (unknown) 6 years ago Like

flotation of platinum group metal ore materials in malaysia. 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 1931 of Rustenburg Platinum Mines Limited to work these deposits and this company

Processing of platinum group metal ores,The presented study is devoted to a comparative review of the mineral raw material base of platinum

To extract the platinum group metals from the ore, and to refine them to the very high purity required for their many applications, requires a multitude of complex operations. At present the final refining stage that produces the individual platinum group metals is carried out by selective precipitation from a solution of mixed platinum group metals, but this is inefficient as far as

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,

GROUP METALS (PGMs) Introduction The six platinum group metals (PGMs) occur together in nature alongside nickel and copper. Mineable deposits of PGMs are very rare, with annual production amounting to around 400 tonnes, several orders of magnitude lower than many common metals. Due to their economic values and higher quantities, platinum and,

Platinum Metals Rev., 2004, 48, (3), 125Œ132 125 Most of the primary platinum group metals (pgms) comes from low-sulfide platinum ores (South Africa and the U.S.A) and from sulfide cop-per-nickel ores (Russian and Canadian deposits). Recent exploration in Russia and elsewhere has resulted in the discovery of some new deposits of

10-12-2018· The platinum group metals (PGMs) are six transitional metal elements that are chemically, physically, and anatomically similar. The PGMs are the densest known metal elements. Exceptionally rare, the six metals naturally occur in the same ore bodies. They are highly durable and, due to their high value, often recycled, giving them long life cycles.

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
