Bioleaching is industrially applied to recover e.g., copper, cobalt, nickel and zinc from sulfidic minerals. Refractory gold ores, in contrast, are processed via biooxidation, which is a bioleaching process where the sulfidic host mineral is dissolved but the target metal remains in the residue for further chemical extraction.

The Minerals Laboratory (TML) of BHP Minerals proposed a novel leaching process in which substantial PGM recoveries from oxidized ores were achieved. Improved recoveries of 95% for gold, 85% for platinum, and over 65% for rhodium were achieved when the oxidized ore from the Hartley ore was processed using the TLM process.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to …
These ores are not just the cradle of platinum but also house a group of elements known as the platinum group metals (PGMs), which include palladium, rhodium, ruthenium, iridium, and osmium. These ores are generously deposited in several parts of the world, with South Africa, Russia, and Zimbabwe being notable for their rich reserves.
The presented study is devoted to a comparative review of the mineral raw material base of platinum group metals (PGMs) and technologies of their processing in South Africa and Russia, the largest PGM producers. Mineralogical and geochemical classification and industrial value of iron-platinum and platinum-bearing deposits are …

The Platsol® process is a high-temperature (>200 °C) pressure oxidation (∼700 kPa O 2, 3200 kPa total pressure) sulfate-based process with additions of 5–20 …
It is estimated that there are about 2500 metal producing mines, 2500 industrial minerals operations, and almost 100,000 quarries producing aggregates for construction purposes that are of "industrial scale" (not small scale or artisanal mining) operations (Ericsson 2012).Open-pit mining accounts for about 83 % of the total industrial metal mining …
Section snippets Mineral ores. Ores from four different shafts were chosen for the study, i.e. Salene (x 1), Waterval UG2 (x 2), Paardekraal (x 3) and Townlands (x 4).All four ores were from the UG2 reef. The last three ores (x 2 to x 4) are the main feeds to the Waterval UG2 Concentrator while Salene (x 1) was selected as a known poor quality …
The aim of this paper is to investigate the effects of ore blends on the mineral processing of platinum ores. The study is conducted using a simplex lattice mixture design for a range of ores of relevance to the Waterval UG2 Concentrator. The main aim of the paper is to determine whether blends of ores display linear grinding and flotation ...

Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in …

Studies on various platinum ores have shown that rheologically complex behaviour is dependent on the amount of phyllosilicate alteration minerals, with ores such as Platreef and Great Dyke being potentially problematic [76,77]. Rheology has an influence on most of the processing steps on platinum concentrators.
