ferrous metals by a complex treatment of the flotation products from South African platinum-containing chrome ores. The procedure involves: autoclave leaching, roasting, hydrochlorination and precious metal recovery by sorption. Autoclave oxidative leaching of the initial material
respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized. The reagents used for flotation are generally not toxic, which means that tailings disposal costs are low.

Research highlights The effect of different comminution procedures on the flotation of PGM ores was studied. As opposed to BMSs the worst flotation performance with PGMs was observed with dry milling. ToF-SIMS, XPS and MLA were used to study the surface of particles to explain the results.

concentrations. The traditional flotation cell consists of a stirred tank incorporating air injection. In recent decades columns have appeared to offer advantages for platinum flotation. This project is a comparative study of the use of column and mechanical cells as cleaners for the flotation of an UG-2 (Upper Group 2) platinum ore.

Flotation was used for the first time to produce a sulphide platinum concentrate in 1926, at Potgietersrus. 28 . The weakening of the platinum price in the early 1930s led to widespread closures and amalgamations, resulting in the formation of a single dominant company, Rustenburg Platinum …

Introduction to Mineral Processing. Froth Flotation Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer ...
Typical applications of flash flotation can be found in gold, silver, platinum and other PGMs, lead, copper, nickel, and combinations thereof. It is worth noting that typically flash flotation is not extensively evaluated during a feasibility study and hence it is unknown if it would be …

Tailings obtained with the modified procedure were higher in platinum and palladium content (0.02 oz/ ton Pt and 0.11 oz/ton Pd) than those obtained from flotation in high acid pulps. Substituting sulfurous acid for sulfuric acid to decrease the pH to 4 and floating with a suite employing MBT was not successful.
SNF FloMin C products are widely used for the flotation of copper, lead, zinc, gold, nickel, platinum group elements and others. Although our base products consist of the traditional known chemistries, we also have active programs in place for developing site specific blends and new products across the froth flotation spectrum.
1 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
Existing processes for the recovery of platinum group metals (PGM) from UG-2 ores place stringent requirements with regard to chromite content (about 2.8 per cent) upon feed material to the plant. The conventional process sequence involves: smelting of a flotation concentrate to remove gangue material and to produce an iron-nickel-copper-PGM matte

Sep 19, 2014· How is platinum extracted from its ore 1. How is platinum extracted from its Ore? An ore is a naturally occurring mineral from which a pure metal can be extracted. For Platinum, the two- chief minerals are sperrylite or platinum arsenide (PtAs2) and co-operate or platinum sulfide (Pts).
The Great Dyke, Zimbabwe, contains over 800 million ounces of platinum and approximately 20 million ounces of rhodium. However, about 10% of the ore is oxidized and cannot be processed with current recovery methods. A conventional flotation-smelting process has been proposed to recover the platinum group metal (PGM) values from the sulfide ores.
