Abstract

Refractory gold ores or concentrates require an oxidation pre-treatment step such as roasting, pressure oxidation and bacterial oxidation to allow the contained gold to be amenable to the subsequent leaching step. When compared to other commonly applied oxidation techniques, biooxidation method has the obvious advantage of both economical and environmental points of view. In this review, the fundamental principles of biooxidation were described as well as an explanation of the important microorganisms and factors that affect their performance. For addition, the proprietary biooxidation technologies that have been commercially applied and commercial plants around the world were introduced.
