THE ALBION LEACH REACTORTM

Albion Leach Reactor is designed to operate at close to the boiling point of the slurry, and no cooling is required. Leaching is carried out autothermally, and the temperature of the leach slurry is set by the amount of heat released by the leaching reaction. Heat is not added to the leaching vessel from external sources, and

Heaps and extracts - ALTA Metallurgical Services

The primary leach vessels are linked to this satellite reactor, and the leaching materials circulate between the two. The SMRt gently scrubs the surface of the particles causing abrasion of passivating films and exposing reactive mineral surfaces. The abrasion of the particle surfaces is balanced to match the leach rate of the particles, so .
