Heap Bio oxidation of Sulfide Concentrates

Next, a thin layer of gold bearing refractory sulfide concentrate is coated onto the sized rock. The coated support rocks are placed in a heap or vat, inoculated with iron and sulfur oxidizinganisms and allowed to biooxidize. After biooxidation, several processing options are available, but typically the coating is removed and gold is recovered via traditional cyanide leaching processes.
