:: SGS Minerals Gets on Board Albion Process

 

Glencore Technology and SGS Minerals (Lakefield site) have announced an agreement and certification that sees SGS becoming the latest laboratory to be certified to conduct amenability level Albion Process™ testwork.

SGS is a highly trusted provider of laboratory testwork services and becomes a valuable supplier to Glencore Technology, expanding testwork capability throughout the Americas. SGS successfully performed Albion Process™ testwork on a gold/pyrite concentrate and a copper/gold concentrate.

The Albion Process is emerging as a remarkably competitive proposition in Hydrometallurgy, and SGS becomes only the third certified provider of testwork, joining Core Resources in Australia and TOMS Institute in Russia.

The testwork certification is important to both companies because the correct performance of the testwork is key to the successful full scale implementation of the Albion Process™ on which performance guarantees are based.

While the number of certified laboratories will expand in other key geographic areas, it will be kept to a relatively small number to maintain quality.

Glencore Technology’s Mike Hourn, said “We are delighted to see SGS Lakefield join the family of laboratories with the capability to perform Albion Process™ amenability testwork. They’re good at what they do and SGS represents a significant presence for us in the Americas and their network is highly valued by Glencore Technology.”

SGS Lakefield’s Niels Verbaan said, “SGS is pleased to be accredited by Glencore Technology on Albion Process™ Testwork and looks forward to working with its clients to provide an objective opinion on the available process options”

Albion Process™ is a combination of ultrafine grinding and oxidative leaching at atmospheric pressure. The feed to the Albion Process™ are base or precious metal concentrates. The sulphides in the feed are oxidised and valuable metals liberated, with the economic metals recovered by conventional downstream processing.

Independent analysis presented at Extraction 2018 suggested it has much lower capital cost than traditional leaching technologies like pressure oxidation (POx) plants (Clary et al. 2018).

Albion Process™ tolerates a more variable feed and lower grade to work where others may not. It can therefore make some projects feasible and profitable where alternative technologies were unable to.

Albion Process™ has success in delivering consistently high recoveries in refractory gold and in copper concentrates with six plants in operation globally.
