ABSTRACT:
A process for the biological oxidation of sulfide in sulfide-containing ore. Preferably, the ore is then subjected to cyanide leaching. The resulting leach tail solution can be subjected to cyanide precipitation, employing ferric sulfate which is generated during the biological oxidation step of the process. Furthermore, a process for efficiently aerating the ore slurry during the biological oxidation step is provided.
