The Albion ProcessTM

The 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 liberated, allowing the wanted metals to be recovered by conventional means.

The Albion Process™ was developed in 1994 by Glencore and is patented worldwide.
There are four Albion Process™ plants currently in operation. Two plants treat a zinc sulphide concentrate and are located in Spain and Germany. Another plant is operating in the Dominican Republic treating a refractory gold/silver concentrate, while the fourth plant is also treating refractory gold in Armenia.
