ABSTRACT A process of recovering platinum group metals PGMs from a pregnant solution or leachate containing PGM values and base metals, typically a cyanide solution or leachate. A non-selective precipitation of the PGM values and base metals to form an insoluble precipitate comprising the PGM values and base metals is followed by selective leaching of the precipitate.
The higher PGM recovery was also accompanied by higher chrome content as a result of their similar chemical properties. Keywords- Metal sulphides, gangue phases, recoveries, Platinum Group Metals, Bushveld complex I. INTRODUCTION HIS article concentrates on the effect of pH on the recovery and grade of PGMs from UG2 ore by flotation.
Mar 30, 2021 From the liberated PGM, conclusions can be drawn on the floatability of the various PGM species for a given flotation regime since liberated PGM species can be directly linked to flotation response. In total 1529 liberated grains were studied from the two ores and their flotation products.

to column flotation, resulted in a higher grade and recovery of PGM as compared to conditioning by means of the recirculation pump. The PGM grade when gentle conditioning was employed was 9 ppm higher for a common PGM recovery of 80 for both conditioning techniques. Finally it was found that increasing the column height improved the grade-recovery

flotation of platinum group metals PGM have significantly improved the rejection of gangue. Coupled to this is an improvement in kinetics, grade and recovery of PGMs. In a pilot-plant trial, after a 5 mole per cent replacement of the current DTCDTP collector combination by C12-TTC, large opaque bubbles were replaced by small clear ones.

A conventional flotation-smelting 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 are now possible.
Lignosulfonates often abbreviated as LS were one of the first dispersants added as an admixture to concrete. Lignosulfonates have been used since the 1930s as plasticizers or water reducers. Mixed with concrete, their use has afforded the beneficial effects of retarding the setting time and reducing the amount of mixing water required.

The production of specialty grade chrome concentrates decreased by 27.2, from 98.9 kt in the last quarter of FY2018 to 72.0 kt.
The Bushveld Complex hosts several layers rich in Platinum Group Metals PGM, chromium and vanadium, and constitutes the worlds largest known resource of these metals. The Waterberg Project is situated off the northern end of the previously known Northern Limb, where the mafic rocks have a different sequence to those of the eastern and ...

Aug 14, 2015 Two ores were used, viz. a base metal sulphide BMS and a platinum group mineral PGM UG2 ore. Flotation was used as a diagnostic to investigate whether the different milling procedures may have different effects of the floatability of the particles.
Flotation is also the best method for recovery of gold from base metal ores and gold-containing platinum group meta-ls PGM ores. Excluding gravity preconcentration, Sotation remains the most cost-effective beneRciation method.

modest impact on the flotation process, with an indication that leaching treatment rather depresses gangue flotation than enhancing valuable recovery. In comparison, the samples treated in batch stirred tank reactors showed an actual decrease in PGM and base metal upgrade and recovery, and flotation appeared to become entirely unselective.

has triggered interest in exploration of techniques for PGM recovery from near surface oxidised PGM ores. All earlier attempts to process the oxidised PGM ores by conventional flotation methods achieved poor recoveries typically less than 50 hindering the commercial exploitation of these resources.
May 24, 2019 increase in the recovery of copper, nickel and PGM in the flotation of the low-sulfide platiniferous Cu-Ni ore from the Fedorovo-Panskoye deposit. The substitution of OPDTC for BX makes it possible to increase recovery of Pt by 13 , Pd by 9 and 2 4 times the noble metal content in the flotation concentrate. 1. Introduction
