An unusually thick 1 cm slime developed on a slump of finely disseminated pyrite ore within an extreme acid mine drainage site at Iron Mountain, near Redding, Calif. The slime was studied over the period of 1 year. The subaerial form of the slime distinguished it from more typical submerged streamers. Phylogenetic analysis of 16S rRNA genes revealed a diversity of sequences that were.

A process for bio-oxidation of sulfides in mineral ore having a metal such as gold occluded or dispersed within the ore as a sulfide is disclosed. The first step comminutes the ore into particles with a size distribution having a P80 of less than 0.25 inch with minus 106 micron particles in the range of 15 to 40 by weight. Agglomerates are formed by adding to the comminuted ore particles an.

Although some microorganisms are capable of using both energy sources, a combination of iron-oxidizing and sulfur-oxidizing microbes often works best. The production of sulfuric acid and the need to keep the most important mineral-oxidizing agent ferric iron in solution means that the organisms are acid tolerant.

2020-1-1Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid. Ferric sulfate, which is a powerful oxidizing agent, then oxidizes the copper sulfide minerals and the copper contained is then leached by the sulfuric acid formed.
