The solution represents transformational change achieved through the commercialisation of new, environmentallyconscious ore processing that sets a new ''gold standard''.
Instead of only going after gold nuggets and flakes, we examined the subject of mineral extraction at a microscopic level. With our proprietary, proven and cost effective technology we are able to extract up to 90% (or more) of the gold present in mine tailings. Developing the technology and proving it could be done was only the first step.

Prospecting Mine Tailings using a Keene RC1 Pilot Mill (GForce Rock Crusher). Hand Cobbled means the the old time prospectors looked at the chunks of ore they dug out and if they did not see gold and the weight was not unusual for the its size, the chuck of ore became discarded.
TECHNIQUES AND TAILINGS The Gold Rush was an epic of technology, as a multiethnic polyglot of Californians re discovered and/or reinvented the technology of mining. By the mid 1850s the "cream" was quickly skimmed from shallow stream bars and benches by the initial rush of miners using shallow handmining
DRD Gold, one of the first South African companies to abandon traditional mining to focus on extracting gold from tailings. New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US40 million, in .

This has not been common practice in the industry to date, as the Mount Polley case has shown, and the synergies to be achieved are mostly unexplored. Apart from this, surface storage using filtered tailings technology is a prime candidate for BAT."
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
tailings impoundment facilities, mercury retorts and mercury free techniques. Technical alternatives for smallscale gold mining, however, must be thoroughly evaluated, pretested, modified accordingly and successfully transferred. Moreover, technology must be inexpensive, relatively simple and easy to adapt, while allowing a rapid rate of return.
