The Metallurgy of Cyanide Gold Leaching – An Introduction

The Albion Process ™, developed at Core's laboratories in the 1990's, is one such process and is now in use globally (see a recent report on a gold Albion Process plant here). Other processes for treating refractory ores include Pressure Oxidation (POx) and Bacterial Leaching (BIOX®).

Copper extraction - Wikipedia

Subsequent steps depend on the nature of the ore containing the copper and what will be extracted. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant.
