iCON Gold Recovery is a Mining Equipment Manufacturer that makes Mineral Processing Equipment for Fine Gold Recovery and other fine mineral recovery. iCON was designed by the professional engineers at Falcon Concentrators and uses the same patented technologies used at the largest mines in the world.
Precious metals may be recovered from the gold ore or from refining processes of base metals such as copper and lead. Because these are distinct recovery methods, they are discussed separately. Precious Metal Recovery from Ores In 2000, gold was produced at 641 load mines; about a dozen large placer mines; and numerous small placer mines.
The recovery of these precious metals is no small issue. While a modern recycling facility can recover as much as 95 percent of gold, in developing countries, the crude dismantling processes employed may recover only 50 percent of this precious metal.

Recovery % Represents the ratio of the weight of metal or mineral value recovered in the concentrate to of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available. By assays f, c and t only: R = 100 c(f — t)/f (c — t) = recovery %
While miners historically could only gather gold in chunks, new technology allows the recovery of up to 40 percent of the gold left in particle form in the dumps. [pullquote]

industrial scale. The recovery of several other metals are also possible by such methods. Insitu, dump, heap and bioreactor leaching are the techniques practised in microbial leaching. In particular, heap leaching in the presence of bacteria is a very useful method to recover copper, uranium and gold from low grade ores and tailings.
Since the design of the CC690 Power Sluice was based on these quantitative studies, as opposed to guesswork or tradition, this product better helps small scale gold miners in extracting the greatest percentage of gold possible from the gravel that gets fed into the CC690. Existing sluice designs rely mainly on gravity to capture gold.
