One of the primary aspects of the business is toll refining. This is the processing, recovery and refining of materials (e.g. concentrates, residues, jewellery scrap, auto catalysts, electronic scrap) that contain gold, silver and the six platinum group metals: platinum, palladium, rhodium, ruthenium, iridium and osmium. This is in general performed on behalf of the owner with recovered and refined metal(s) being returned in a form of their choice.

Gauteng Refinery has no set of terms and conditions, and agreements are structured to suit
individual clients.

Each batch of material from a customer is processed individually and retains its identity throughout the process, thus maintaining the integrity of the metal accounting principles, as well as ensuring an accurate and precise metal balance across each batch of material processed.

The company has an established relationship with INTL FC Stone, an international metal trader and finance house for the financing of the refining metal inventory and pipeline, on behalf of Gauteng Refinery’s clients.

Gauteng Refinery’s client base includes corporate organisations such as Anglo American, De Beers, Pan African Resources and Rand Refinery.

Feedstock for toll refining is sourced in a manner which ensures conformance with the Organisation for Economic Co-operation and Development’s (OECD) Due Diligence Guidance for minerals from conflict affected and high risk areas, as well as the requirements of the Responsible Jewellery Council (RJC) and the London Bullion Market Association’s (LBMA) Responsible Gold Guidance.
