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