ABOUT MINTEK

Mintek is an autonomous research and development (R&D) organisation specialising in all aspects of mineral processing,

extractive metallurgy and related technology. Working closely with minerals and metal producers locally and internationally,

Mintek develops and transfers innovative, new and improved technology to industry for processing, extracting, refining

and utilising minerals and mineral products.

Mintek offers R&D expertise, service testwork, and technologies for the gold, platinum-group metals (PGM), base metals,

ferro-alloys, and industrial minerals sectors. Extensive laboratory and pilot-plant facilities are available for investigations

in the following fields:

• Analysis - characterisation of ores and other materials, analytical chemistry and mineralogical techniques;

• Mineral processing - comminution, flotation, gravity, electrostatic, magnetic, and dense-media separation;

• Hydrometallurgy - leaching, bacterial oxidation, adsorption (CIP and RIP), solvent extraction, and electrowinning;

• Pyrometallurgy – pre-heating and pre-reduction, submerged-arc and DC transferred-arc smelting, converting,

condensing, and process simulation; and,

• Other specialised technologies - metallurgical process control and optimisation, tank and heap bio-leaching of

gold and base metals, alloy development, pollution studies, residue processing, and techno-economic studies.

Mintek’s activities range from initial investigations to complete process development and, in conjunction with engineering

partners, the design, construction, and commissioning of plants.

MINTEK’S ANALYTICAL SERVICES DIVISION

Mintek’s Analytical Services Division (ASD) is a well-established analytical chemistry laboratory that specialises

in geochemical and general analytical chemistry. We provide analytical support to clients in the mineral,

metallurgical and related industries, using state-of-the-art instrumentation for a variety of techniques.

Our highly skilled scientists and analysts are backed-up by a top-quality consulting team, all operating

according to ISO standards. We have a wide range of facilities that ensures a quality one-stop for exploration

and general analytical services.
