Abstract
The present invention is directed to microbiological processes for the oxidative treatment of refractory gold and base metal ores and concentrates, and particularly, an apparatus for testing refractory gold and sulfidic base metal ores for their suitability to heap biooxidation or bioleaching processes. The invention can be used to simulate heap biooxidation. This apparatus incorporates features of heap biooxidation and may be used to generate engineering data for creating detailed process and engineering designs. The invention can be used to develop a select population of bacteria geared to optimize biooxidation of a specific refractory ore.
