Apr 13, 2020· Because platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another. This is known as the flotation separation method, and produces a frothy layer of particles that can be skimmed to provide the extracted platinum.

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 ...

Aug 21, 2020· The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. During flotation, air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.

Wills' Mineral Processing Technology provides practising engineers and students of mineral processing, metallurgy and mining with a review of all of the common ore-processing techniques utilized in modern processing installations. Now in its Seventh Edition, this renowned book is a standard reference for the mineral processing industry.

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.

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.

Aug 29, 2021· She is Director of Processing at Newmont Goldcorp Corporation, USA. Ronel has metallurgical development experience in a wide-range of commodities,including gold, copper, lead, zinc and platinum group metals and is passionate about flotation, gold hydrometallurgy and mineral processing in general.

Mineral processing. Solvay's reagent portfolio includes offerings designed for the recovery of precious and base metals, such as copper, molybdenum, gold, nickel, cobalt, platinum group metals and polymetallics. We also offer products for various industrial minerals such as phosphate.

The evolution of Froth Flotation in Anglo Platinum can be simplistically summarized into three different 'concentrator eras' as follows: Flotation cell technology and circuit design—an Anglo Platinum perspective by C.M. Rule* and A.K. Anyimadu* Synopsis Froth flotation is the primary mineral processing separation step

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). …

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.

Crushing, grinding and flotation are featured in this latest educational video. Silver, Gold, Platinum, Palladium and other PGM ore. Careers and technology...

Kell Technology. The Kell Process has been developed for extraction of platinum group metals (PGM), gold, silver and base metals from PGM sulfide flotation concentrates without smelting.

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 …

FLOTATION Flotation is the most widely used mineral separation method.
