2021-3-22 A Knelson or Falcon concentrator is designed to process fine, free gold that does not require cyanidation for recovery. These use the principle of centrifugal force which aids in the separation process based on the particle density. In the laboratory, these generally are operated as batch processes but can be made to operate continuously.

2006-12-5 During the past 30 years, many techniques used by industry to recover gold and silver were pioneered and developed by the Bureau of Mines. In 1952, technology was developed to strip gold from granular activated carbon and allow the carbon to be reused. In 1969, the heap leaching concept was applied to low-grade gold and silver ores and mine wastes.

The Musselwhite Mine in Canada processes a free milling gold ore at 5.5-5.8g/t Au and 4.2% pyrrhotite. A laboratory investigation was conducted to improve cyanidation. The pyrrhotite was determined to be 50% monoclinic and 50% hexagonal. A leach using 8ppm dissolved oxygen yielded only 82.3% gold extraction with a 0.29kg/t NaCN consumed. The addition of lead nitrate, directly to the leach ...
