Title: Recovery of metals from ore
Inventor: LASTRA MANUEL R
IPC: C22B19/20
Filed: 2000-10-31
Abstract: A bio-leaching method is provided for recovering metal from a metal containi ng ore. The ore is subjected to contact with a microorganism selective to the oxidation of sulfur. A sulfur containing compound is mixed with the microorganism before, during or after contact with the ore to systemically form sulfuric acid to leach the metal from the ore. The ore is in the form o f a slurry, a heap, a charge in a vat and is bioleached for a time sufficient to dissolve the metal in the ore and form a metal-rich leachate and an ore residue. The metal can then be extracted from the metal-rich leachate. The metal containing ore may contain base metals, precious metals, or platinum group metals. Upon formation of the metal-rich leachate, the ore residue may  be further processed to recover any precious metals or platinum group metals  that may be present.
