Waste Management. As with any mining activity, New Gold's operations generate process waste. Process waste includes barren rock (not containing economically viable minerals) in the form of tailings or waste rock (coarser broken rock), which must be stored in a geochemically and geotechnically stable manner.
Tailings Management. Tailings from mining operations are usually stored in large tailings dams as a slurry that contains the waste materials from the beneficiation process. This slurry includes mineral material, metals and any reagents used in the beneficiation process.
OUR CLAIM: The MultiHelix Spiral is "hands down" the most efficient gold concentrator available in the industry. It has a proven track record with a recovery rate of 99% of all free gold. It is a commercial duty, gravity concentrator for both alluvial and fine milled hard rock ores and has the highest concentration ratio AND highest recovery rate of any gravity concentrator on the market ...
