CIL Carbon in Leach process is the most efficient method to leaching and recovering gold from gold ore, The most protruding features is that leaching and adsorption are carried out at the same time, which greatly saves the cost of construction and operation. It has become the first choice of modern gold mining and processing plant design.
Years ago I heard about some guy who supposedly had a new process for gold extraction from gold bearing soils, and he got some people interested in it, then raised a bunch of bucks and even got a ...
Gold without tears GOLD EXTRACTION DRA was the major engineer for the largest gold processing plant in Africa at Kibali gold mine in the remote northeast of the DRC. The value of the scope under DRA control for the plant and infrastructure amounted to 906 million. This included a two-stream processing plant, two tailings dams, a 22 MW hydropower
On Tuesday morning, villagers took to the streets in Himeid in Northern States Wadi Halfa locality in protest against a gold extraction plant in the area. The demonstrators were forcibly dispersed by security and police forces. The demonstration was organised by the Five-party Anti-mining Committee of the villages of El Sukout, where the Hasour Company plans to build a gold cyanidation site.
Two primary methods, Carbon In Pulp CIP and Carbon Columns probably comprise the most widely utilized techniques for extracting gold, now days. In CIP, the carbon is mixed with the cyanide leach solution, and agitated in the leach tanks, and agitated with the ore while the gold is being dissolved.

The cyanide is regenerated as free cyanide and recycled to the gold extraction circuit. We have designed and constructed full-scale plants, provided process review and commissioning for a plant under construction, and carried out flowsheet development and testing programs for SART.
Cyanide process is also called as Macarthur-forest Process. It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by the Scottish chemists naming Robert W. Forrest, John S. MacArthur, and William Forrest.
