Introduction Southern Africa, specifically South Africa and Zimbabwe, hosts the worlds largest deposits of platinum group metals in the Bushveld Complex BC, South Africa and in the Main Sulphide Zone MSZ of the Great Dyke in Zimbabwe.gravitational concentrate was 1434 g with a yield of 2.26 of the original sample. Tailings yield was 97.7 . The KC-MD concentrates obtained in each stage were subjected to cleaning on the concentration table TCO. In the process of reduction of probe mass 4.4 times three samples of 115 g, 92 g and 118 g were obtained.ter usage, PGM bearing ore flotation circuits make use of recycled process water. Howev - er, the chemistry of recycled process water may alter the performance of the flotation sys-tem. It is therefore required to understand the effects of these elements on the flotation process.

Processing of PGM involves comminution, flotation, smelting, converting, base metals refinery and precious metals refinery.The mineralogy of the platinum group metals is fairly complex, and it is therefore not surprising that the different . minerals have variable responses to metallurgical processes, in particular, flotation and leaching.Trithiocarbonates for PGM flotation T r by C.F. Vos, J.C. Davidtz, and J.D.Native metals and most of the PGM minerals float over a range of pHs, so a lower flotation pH would be acceptable. Well I guess basically says that a lower pH should be OK for good flotation recoveries with your ore.

It is speculated that different inorganic constituents of process water may yield different flotation results owing to electrolyte-reagent-mineral interactions occurring in the pulp phase.Russia and South Africa are the worlds leading producers of platinum group elements PGEs. This places them in a unique position regarding the supply of these two key industrial commodities.Provided is a method involving flotation of a feed of platinum group metal ore material to prepare a platinum group metal concentrate during mineral processing operations. Prior to andor 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 nitrogen gas, is used.Trithiocarbonates for PGM flotation C.F.

Separating The Platinum Group Metals By Liquidliquid

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 the ...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.A process of recovering platinum group metals PGMs from a pregnant solution or leachate containing PGM values and base metals, typically a cyanide solution or leachate. A non-selective precipitation of the PGM values and base metals to form an insoluble precipitate comprising the PGM values and base metals is followed by selective leaching of the precipitate.Centrifugal Fecal Flotation Technique. The following instructions are for the technique we will be using in the laboratory sessions. The centrifugal flotation technique you will practice in the laboratory is a two-step process with the first step being a wash to help decrease the amount of fecal debris.sub-process where hydrophobic minerals are attached to the bubbles rising through the pulp. Entrainment is described as a non-selective physical sub-process where solids and water are transferred to the froth in the bubble lamella and bubble interstices. In the recovery of PGMs and BMSs to the concentrate, the predominant process is true flotation.Sep 01, 1991 18.7.2 Flotation properties of PGM from sulphide-dominated deposits 18.7.3 Reagent practice in flotation of PGM sulphide-dominated ores 18.7.4 Reagent practice in flotation of CuNi and Ni ores with PGM as the by-product 18.7.5 Reagent practice in flotation of PGM from chromium-containing ores 18.7.
