The third step is the extraction process. This is done by crushing the ore into minuscule pieces, once this is done the next process the platinum must proceed through is the flotation separation process, which relies on air particles to push the Platinum particles to the top. They are then skimmed off for refining.
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.
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 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 nitrogen gas, is used.
The complex process for refining platinum. Image from UNCTAD. A platinum flotation circuit. In a process called flotation separation, air bubbles are blown through the mixture and carry platinum particles to the surface of the bath. The platinum-rich froth is skimmed from the bath and allowed to dry into a concentrated powder.

Flotation is nowadays the best method for the recovery of gold from base metal ores and gold-bearing ores like the PGM(The platinum group metals) ores. also, it's the most cost-effective beneficiation method.Since JXSC founded 3o+ ago, we have accumulated a lot of rich experience in gold flotation processing.
Because the ore is sulfidic in nature, it was concentrated by froth flotation. A 45 kg/h process development unit (PDU) was constructed and 85 to 95% of the platinum and palladium were recovered from the ore by using mercaptobenzothiazole or sodium isobutyl xanthate as collectors.
Impala Platinum Limited is the world's second largest platinum producer, producing more than 1.7 million ounces of the precious metal last year, much of this from the UG-2 reef located in the Bushveld Complex, South Africa. As part of Impala's ongoing expansion programme, tonnage through their principal UG-2 processing facility, near

The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. First of all, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry. A Collector which …
process control of flotation systems have been reported, particularly in the platinum industry. One of the reasons is that to date froth features could not be related to key performance indicators such as froth grade and recovery. The research focus areas have been the use of froth appearance to detect predefined operational states (Moolman et al.

Platinum producers are evaluating hydrometallurgical process routes to extract platinum group metals (PGM) and base metals (BM) from flotation concentrate that are alternative to conventional pyrometallurgical matte smelting treatment of flotation concentrates. This approach would attract several potential benefits to the cost-effective ...
FLOTATION Flotation is the most widely used mineral separation method. It is the preferred method of mineral recovery for many of the most important minerals that are recovered and large tonnages of ore are processed by flotation annually. The underlying principles of the flotation process are well established but it has proved to be

The present invention is primarily directed to flotation processing of platinum group metal ores, even though those ores may include platinum group metal as a by-product only, and particularly as a by-product of a base metal ore containing significant nonferrous base metal values such as copper and/or nickel. In one aspect, however, the present ...
Jun 24, 2017· The platinum-group metal content was more than twice that of a rougher concentrate, and the Al2O3 and CaO contents were significantly lower (see table 7). Because flotation concentrates would be subsequently treated by smelting-leaching or direct leaching techniques to recover platinum-group metals, impurity contents are an important consideration.
Nov 06, 2017· The beneficiation of platinum group metals (PGMs) from pristine (unweathered) sulfide ores has conventionally been conducted through froth flotation, which typically achieves platinum recoveries of over 85%. The achieved successes of PGM concentration by flotation from the pristine sulfide ores are largely due to the occurrence of PGMs in close association with base metal sulfide …
Froth flotation is a process for selectively separating 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.
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.
