concentration platinum flotation

Platinum

A flotation method using mercaptobenzothiazole collector in an acid circuit was devised for preparing a platinum-palladium concentrate from Stillwater complex gabbro (Montana). Bench-scale experiments showed that rougher flotation recovered 91 pct of the platinum and 88 pct of the palladium in a concentrate assaying 2.6 oz/ton Pt and 8.8 oz/ton Pd.

TECHNICAL NOTES 9 FLOTATION

8.1 A Kinetic Approach to Flotation Modeling Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment

Platinum

This very sensitive flotation-spectrophotometric method is based on the ion associate formed by the anionic chlorostannate(II) complex of platinum (II) with the xanthene basic dye Rhodamine 6G (formula 4.30) [41]. When the aqueous phase is shaken with DIPE, the sparingly soluble compound collects on the wall of the separating funnel.

These benefits have been extensively demonstrated on the UG2 ore body, part of the ...

Investigations into the Recovery of Platinum Group ...

In the flotation of platinum group minerals (PGMs) it has generally been assumed that they will behave similarly to base metal sulfides and thus sulfide reagent regimes are generally used in such flotation plants. However the tellurides and arsenides of platinum and palladium contribute about 50% of the PGMs present in the Platreef ore, located in the northern limb of the Bushveld Complex of ...

hard rock in platinum mines has a high thermal gradient, to refrigerate the working areas. On the surface the ore is crushed and milled into fine particles. Wet chemical treatment known as froth flotation produces a concentrate which is dried and smelted in an electric furnace at temperatures over 1,500°C. A …

Froth Flotation Principles

The Froth Flotation Machine and its operating principles are universally used for all types of flotation problems.This machine finds a wide acceptance due to its flexibility in construction, which allows the machine to be adjusted to handle pulps with divergent physical characteristics, as well as the common and intricate metallurgical problems which confront the present day operator.

The flotation method of separation of multicomponent mixtures

For example, enter another operation control flotation chamber product for the separation of multicomponent high-grade matte containing platinum, thus using hydrogen as process gas in the aerator on the proposed solution can increase the hydrophobicity of the particles of platinum group metals and withdraw the main amount in the layer.

Flotation | ore dressing | Britannica

Flotation is the most widely used method for the concentration of fine-grained minerals. It takes advantage of the different physicochemical surface properties of minerals—in particular, their wettability, which can be a natural property or one artificially changed by chemical reagents.

Platinum Beneficiation

After DMS the sink fraction is further milled and then sent to flotation. The remaining material is sent for secondary milling, flotation, and thickening phases – allowing an environment-friendly, pre-cycloned material to be deposited for tailings. The mineral-rich feed is then moved into a solid/liquid separation circuit via a slurry sampler.
