With the rising price of gold and the limited amount of mineable land, people are now focusing on the recovery of fine gold. Some rivers of the world have been sluiced as many as 6 times, yielding profitable gold each time – and demonstrating that traditional sluices can have very poor recovery. "Small" Gold Wash Plants like the IGR500 focuses on the

The results at Sadiola are consistent with this hypothesis with an overall 4% gain in plant recovery. With total gold recovery of 12% in the gravity section, grades are increased from 3.54g/t in the gravity feed to an average of 2 600g/t in the concentrator feed to the in-line reactor. The recovery of gold in the in-line reactor is in excess of

A more technical definition is that you are able to recover over 90% of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low grade and high grade which helps determine the most economical and optimal gold recovery method. Low Grade.
