Processing of platinum group metals ores in Russia and South Africa: current state and prospects
How to Cite
Presented study is devoted to a comparative review of the mineral raw material base in the case of platinum group metals (PGM) and their processing technologies in South Africa and Russia, as the largest PGM producers. The mineralogical and geochemical classification of iron-platinum and platinum bearing deposits and their industrial value are presented in this work. This article presents an overview of PGM ore bodies abundance types, ore processing methods with a special focus on flotation application, as well as the difficulties encountered by enterprises at the processing stage to increase the recovery of noble components. Furthermore, data on mineralogical features of PGM deposits, including distribution of elements in ores, is provided. The verification of the main directions in mineralogical features and processing of raw materials with various genesis research is validated.
It is established that sulfide deposits are of the highest industrial value in both countries. Such unconventional sources of the PGM as black shale, dunites, chromite, low-sulfide, chromium and titanium-magnetite ores, anthropogenic raw materials, etc. are considered. The main directions of research in involvement of non-conventional metal’s sources in processing have been substantiated.
The review in the field of new processing and metallurgical methods of PGM recovery development from non-conventional and industrial raw materials is conducted. The review of existing technologies for platinum-bearing raw materials processing was carried out. The technologies with modern equipment application for ultrafine grinding are considered, the review of existing reagents for flotation recovery and evaluation of their selectivity in relation to platinum minerals are presented. The analysis of the main technological processes of PGM ores processing has shown that the most effective are the gravity-flotation technological schemes with subsequent metallurgical processing.
