Abstract
The subject invention provides safe, environmentally-friendly compositions and efficient methods for extracting impurities from gold ore. More specifically, the subject invention provides compositions derived from microorganisms for pre-leaching treatments of gold ore, which can be used for reducing carbonaceous material in gold ore.
Claims18
A method for extracting an impurity from gold ore, the method comprising:
- (i) contacting a pre-leaching composition comprising a biosurfactant with a gold ore for a period of time to yield a mixture comprising a treated gold ore and an impurity;
- and
- (ii) separating the impurity and pre-leaching composition containing the gold from the mixture to obtain a reduced-impurity gold-containing material.
