SGS Minerals will offer Albion Process testwork at a lab in Randburg in South Africa, Glencore Technology’s reported. The testwork has also been conducted at the SGS Lakefield lab.
The testwork seeks to qualify an operation for the process.
Glencore Technology said the development is part of a wider focus on the African continent. “The extension has been under discussion for quite some time,” said Paul Voigt, technology manager, hydrometallurgy and pyrometallurgy, Glencore Technology.
SGS is the third certified provider of the testwork. Core Resources in Australia and Toms Institute in Russia offer the service.
Albion Process is a combination of ultrafine grinding and oxidative leaching at atmospheric pressure. It tolerates a more variable feed and lower grade, making some projects feasible.
Currently, at several plants, the process consistently delivers high recoveries in refractory gold and base metal concentrates, Glencore Technology reported.
