REPROCESSING OF A FRENCH GUYANA OPERATION TAILINGS USING FLOTATION FOR GOLD CONCENTRATION

摘要

The use of flotation is an attractive answer to limit the gold losses in tailings and to pre-concentrate gold before cyanidation. The pilot plant tests conducted on site by Caspeo have proved gold flotation feasibility. With the help of the USIM PAC software, the flotation plant has been designed.In addition to the process enhancement, a special attention was made on environmental impact reduction.
