Cyanidation ---carbon adsorption process is the most widely used in gold cyanide extraction process . The principle in brief is the carbon could adsorb liquid gold from cyanide solution . In 1970s , with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold , make recycle the carbon and reduce the cost , and easy to process the gold ...
Gold CIL process carbon in leach is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to 99, which is the first choice of modern gold mining and gold beneficiation plant.

The above pre-treatment stages can be changed based on ore mineralogy. For a complex AuAg ore, direct cyanide leaching resulted in only about 47 and 19 extraction of gold and silver even after very fine grinding at 38 m.Diagnostic leaching was carried out to assess the nature of refractoriness 29.Depending on the results of the diagnostic test results, extraction strategies for gold ...
Aug 22, 2019 The gold content in the placer gold mine is extremely low, and it is known as the gold panning by beneficiate the placer gold through various energy-efficient placer gold equipment. Among various gold extraction methods, the gravity separator method is energy-saving, efficient, environmentally friendly, and is suitable for placer gold ore process.
