Gold is often found in ores with gold particles scattered throughout, called refractory ores, and the small particles of gold are covered by insoluble minerals.

These minerals make the extraction difficult. Therefore, microorganisms that can "eat away" at the mineral coating are used to pre-treat the gold ores before they can be extracted.

Nouveau plans on developing and licensing its patented continuous reactor that will allow more efficient extraction through innovative controls over the entire process.
