An Investigation into the bacterial leaching of a gold-bearing pyrite/arsenopyrite ore
… viable bacterial leaching process for a gold-containing pyrite/arsenopyrite ore. The effect of various parameters on, and the mechanism of, bacterial leaching were investigated. Initially milled run-of-mine ore was examined. Batch tests and a continuous bacterial leach were carried out. …

The batch and continuous bacterial leaching kinetics of a refractory gold-bearing pyrite concentrate
… preoxidation step in the treatment of refractory gold bearing sulphide ores and concentrates, has created the need for kinetic models to adequately describe bacterial leaching reactor performance. This work is a kinetic study of the bacterial leaching of a refractory gold bearing, pyrite …

Mineralogical characterization and paragenesis of the Cripple Creek deposit, Colorado
The world-class Cripple Creek gold telluride deposit in central Colorado is centered on an Oligocene alkaline-magmatic system composed of diatremal Breccia that is intruded by dikes and sills that range in composition from phonolite to lamprophyre. The deposit has historic production of >24 Moz of …
