2011 4 1 Research highlights Online froth image processing is a potentially important approach to estimating the performance of flotation cells and can serve as basis for development of advanced process control systems. The relationship between froth features and grades and recoveries is not well established in platinum flotation yet. This study shows strong
Treatment of Platinum Flotation Products By A. V. Tatarnikov* and I. Sokolskaya All Russian R & D Institute of Chemical Technology, 33 Kashirskoye Road, 115409 Moscow, Russia * The AOL process is considered in 2 . Platinum group metals are present in the insol uble leach residues in natural chalcogenide mineral forms; they do not undergo
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.
2021 9 26 Processing Platinum Flotation. A conventional flotationsmelting process has been proposed to recover the platinum group metal pgm values from the sulfide ores with the development of a low temperature roasting acidic bromine leaching process by the minerals laboratory of bhp minerals substantial pgm recoveries from oxide and mixed oxidesulfide ores
Kell hydrometallurgical process for extraction of platinum group metals MF2 flotation circuits, middlings streams, and concentrates from retreatment of tailings impoundments.
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. Read More
2020 11 24 Russia and South Africa are the world’s leading producers of platinum group elements PGEs . This places them in a unique position regarding the supply of these two key industrial commodities. The purpose of this paper
2002 10 17 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
The present invention involves a method of flotation 112 of a feed of platinum group metal ore material to prepare a platinum group metal concentrate 114 during mineral ore processing operations.
2022 7 15 A flowsheet has been developed for the production of rich concentrates of precious and non ferrous metals by a complex treatment of the flotation products from South African platinum containing chrome ores. The
2019 8 26 The platinum group metals PGM include ruthenium Ru, rhodium Rh, palladium Pd, osmium Os, iridium Ir and platinum. Of these elements, only platinum and palladium are found in a pure form in nature. The others
2020 11 24 Russia and South Africa are the world’s leading producers of platinum group elements PGEs . This places them in a unique position regarding the supply of these two key industrial commodities. The purpose of this paper is to provide a comparative high level overview of aspects of the geological occurrence, mineralogy, and processing by flotation of the
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
Processing Platinum Flotation. high operating cost most platinum mine operations in South Africa have drifting towards mining and processing UG2 ore Most mines process the UG2 ore from open pits and routinely suffers from low and erratic platinum group element PGE flotation recoveries This is due to changes in mineralogy of the ore as a results
What is claimed is: 1. A method for flotation processing a platinum group metal ore material to prepare a platinum group metal concentrate, the method comprising: flotation of a feed of the ore material to produce a flotation concentrate enriched in platinum group metal relative to the feed of the ore material and to produce a flotation tail depleted in platinum group metal relative to the
