One of the primary aspects of the business is toll refining.

This is the processing, recovery and refining of materials including concentrates and residues that contain gold, silver and the six platinum group metals,  platinum, palladium, rhodium, ruthenium, iridium, and osmium.

Primary focus is on gold recovery, newly mined gold in the form of concentrates and metallurgical residues such as carbon fines, silver arisings and Platinum Group Metal metallurgical residues, focusing on iridium and osmium.

This is in general performed on behalf of the owner with recovered and refined metal or metals being returned in a form of their choice.

Gauteng Refinery has set terms and conditions with agreements being structured to suit individual clients needs based on their unique material.

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.


Feedstock for toll refining is sourced through our prescribed Know Your Customer (KYC) process in a manner which ensures conformance with the Organisation for Economic Cooperation 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.

The company has access to facilities provided by an international service provider’s that will facilitate the financing of the refining metal inventory and pipeline. This includes a comprehensive range of customised financial services and tools to help Gauteng Refinery protect its margins and manage volatility. 

Additionally, because Gauteng Refinery has access to an FX pricing platform that can price gold at any time and/or hedge; and with an efficient mechanism for USD/ZAR conversion, the company can provide a more rapid processing and payment pipeline. This mitigates the costs and risks of metal price and exchange rate fluctuations.


A key part of value recovery has been the innovative partnering with mining operations and metallurgical operations for the following :

Site Clean Ups: Based on an upfront resource map and work plan, materials are extracted from infrastructure including equipment, smelt houses, bag houses and precipitators for subsequent precious metals recovery and refining.

Residues: On or off site recovery from materials such as dusts, fines, carbon fines, wood chips and slags.

Waste Materials: - Solid wastes such as crucibles, refractories - Liquid wastes such as mine runoff, tailings dam return water, effluents. Gauteng Refinery has proprietary technology to remove contained precious metals down to a single figure part per million, whilst also treating effluents fit for discharge in compliance with all legislative, sustainable and moral requirements.

Airborne emissions: As with all of the company’s activities, the above is done in close conjunction with Mine Management and Operations Personnel based on full transparency, trust and technical competency.
