{"Image DocumentName": "Gold extraction Gold ore processing", "Image ImageDescription": "Gold recovery: 1) Carbon in pulp. The loaded carbon is then washed with dil. HCl to remove CaCO3 that precipitates on the C. Acid washed C then separated from the pulp in the final tank & transferred to the elution circuit. Barren pulp is dewatered (to recycle water & remove cyanide for reuse in the process). In the elution circuit, the loaded carbon is treated with a hot cyanide & caustic solution to remove the Au. Reversal of adsorption process. Produces a small vol. of soln.
