Description:	Abstract:This research studies the behavior of the gravimetric concentrate from the Ecoluxen company, through tests of cyanidation to determine the operating conditions to obtain the highest gold recovery. A physical, chemical and mineralogical characterization of the material was performed and, through a valuable mesh analysis, it was determined that gold is in greater quantity at 125 μm with 33.65%. In the cyanidation assays, 70.21% gold recovery was obtained for the 68 μm material, with a consumption of 12.69 kg / ton of NaCN and 0.61 kg / ton of CaO, and subsequently a pretreatment of oxidizing roasting of the material was performed to determine if it improves metal recovery Using the chiddey method, the highest gold recovery was 73.15% for the cyanide solution of 73 μm, and finally the economic evaluation was made for the best operating conditions, for 20 tn / month of gravimetric concentrate, using the current price of gold and the cost of reagents of the importer MINASUR, obtaining a profit of $ 17220.40.
