ABOUT US

Gauteng Refinery is part of a group of companies which has been active for over 30 years in precious metals beneficiation throughout Africa.
It is in the business of recovering and refining gold and silver, and the platinum group metals: platinum, palladium, rhodium, ruthenium, iridium and osmium.

VISION

We are a technology driven, proudly African organisation maximising the African continent’s precious metals supply chain from source to end user in a responsible and sustainable manner.

MISSION

Our mission is in unlocking opportunity in the precious metals value chain.

VALUES

We believe that in order to operate in a sustainable and responsible manner, we must live our values every day. They are defined as follows:

Trust

Because of our firm belief in reliability, we are confident that all our stakeholders can be assured of a relationship built on mutual trust and respect. We know our products and services lend credence to this fact.

Transparency

We perform without any hidden agendas or conditions. We make available all relevant information required for collaboration, cooperation and collective decision making.

Technical Excellence

We provide technical excellence through our qualified team of engineers and chemists who are focused on providing quality and innovative products. We also ensure best practice in all our processes (engineering, refining, recoveries, environmental).

GAUTENG REFINERY IS A LEADING GLOBAL SUPPLIER OF OSMIUM

The metal is used to produce very hard alloys for fountain pen tips, instrument pivots, gramophone needles and electrical contacts.
Osmium is the heaviest metal known to man, harder than diamond and it has a very high melting point of 3,033 degrees centigrade.
In addition to osmium, we also synthesise osmium tetroxide (OsO4), which is predominantly used in electron microscopy as a stain to add contrast to digitally scanned images.
There is also currently significant research on new applications such as cancer treatments.

PROFILE

The story of our history introduces the types of services and products we offer and the evolution of our technical experience and expertise. It is through the history of a company older than 30 years that trust and transparency have developed, have become of paramount importance and are maintained to this day.

Our services include refining of precious metals and precious group metals, toll refining, urban mining initiatives, and residues recovery and environmental compliance. These are undertaken at our different processing plants which are located in various areas in South Africa.
