UG-2 also contains minor quantities of copper and nickel sulfides. PGE sulphides comprise roughly 70% of the PGM (platinum group minerals) in the UG-2 plant feed, the remainder largely being alloys of iron, lead, arsenic and antimony,

Investigation of Platinum-Group Minerals (PGM) from

Platinum-group minerals were concentrated using superpanning from two composite chromitite samples, which were collected from two old mines within the Othrys ophiolite. This method allows for the recovery of a broad spectrum of these rare and fine-grained minerals, and helps to better identify them and interpret their origin.THE PRIMARY PRODUCTION OF PLATINUM GROUP METALS (PGMs),Extraction, concentration and refining of PGMs require complex, costly and energy-intensive processes that may take up to six months to produce refined metal from the time the first PGM-bearing ore is broken in a mine. 1 Chamber of Mines of South Africa, Annual Report 2012; figure does not include recycling.Extraction of Platinum Group Metals | IntechOpen,21.02.2018· Gangue minerals associated with PGM-containing minerals are feldspar, biotite, plagioclase and pyroxene . 4.

Complete stripping (>99%) of platinum was accomplished in a single contact using mixture of 1 M NaOH-1 M NaCl. A product solution of 0.89 g/l Pt was obtained. The complete flow sheet of the process is depicted inPlatinum‐Group Mineral Characterization in Concentrates,,The present data are important for both petrogenetic studies and for mineral processing purposes. The study of PGM in polished sections usually fails to give the complete picture of PGM paragenesis expected from whole‐rock analyses (e.g. Malitch et al., 2003).

PGM Characterization in Pindos Ophiolite Complex Chromitites

PGM occur as free particles and in situ textural information is lost, single grain textural evidence is observed. In summary, this research provides information on the particles, grain size and associations of PGM, which are critical with respect to the petrogenesis and mineral processing. of ophiolitic chromitites. These can bePGM ore processing: LIX reagents for palladium extraction,,01.07.2019· As the palladium concentration in the feed was low (∼0.4 g/l), the process was aimed at obtaining higher concentration end product. Besides, the filtrate contained ∼1 g/l Cu, which is co-extracted with Pd. Hence, the concentration of LIX 984 in the organic phase was fixed at 8% and A/O at 5:1. Using these conditions, the palladium concentration in the raffinate was found to be <0.005 g/l,Beneficiation and Extractive Metallurgy of PGE,Elements) and PGM (Platinum Group . Minerals) are often used interchangeably, and incorrectly, in the processing and metallurgical literature. The terminology is confused further by PGM being referred to as platinum group metals (which is strictly correct) but often leads to the abbreviation of PGM, which refers to the mineral and not the metal,

Leaching and recovery of platinum group metals from UG-2,

Existing processes for the recovery of platinum group metals (PGM) from UG-2 ores place stringent requirements with regard to chromite content (about 2.8 per cent) upon feed material to the plant.

These can bePlatinum-group element remobilization and concentration,The combined datasets reveal that the PGE at Cliff have probably been fractionated by an As-rich fluid, concentrating Pt and Ir into visible (0.1–1 µm) platinum-group minerals (PGM) such as sperrylite and irarsite, respectively. The high (>1 ppm) bulk-rock concentrations of the other PGE (e.g. Os) in the Cliff chromitites suggests the presence of abundant fine-grained unidentified PGM in,THE ENVIRONMENTAL PROFILE OF PLATINUM GROUP METALS,PGMs are very rare elements and most PGM-bearing ores are extremely low-grade, with mined ore grades ranging from 2 to 6 grams per tonne. 1 PGM mining is a capital, energy and labour intensive process; extraction, concentration and refining of the metals require quite complex processes that may take up to six months.
