The aim of the present research is to determine if the recovery of gold is possible by the gravimetric method with samples taken from the informal mining area of Ollachea which are mostly carbonaceous phyllite slate rocks that harbor gold mineralization. The experimentation will be carried out with a FALCON L-40 gravimetric concentrator at laboratory level, this equipment is considered according to the bibliography as one of the most versatile, in addition to being productive compared to traditional equipment; within the FALCON equipment, the heaviest particles are retained while the lightest are carried by a flow of water, which are sent to the discharge area. The recovery of gold ore was tested with the factors: particle size and number of cycles per batch, the latter refers to a waterfall-type methodology where a gravimetric reprocessing of the tails is carried out, in this process the first cycle of the reprocessing it is the first batch then in the next cycle the tailings are taken as fresh material and so on until the last cycle is reached. It is concluded that the highest recovery of gold is obtained with the particle size 74 μm and performing 4 gravimetric cycles obtaining as recovery in the first cycle 64.97%, in the second an accumulative recovery of 75.15%, the third cycle 79.73% of accumulated recovery and in the fourth, a cumulative recovery of 82.91% of gold ore, being the static parameters: water pressure 1 PSI, centrifugal gravity 98 G's. The recovery percentage obtained in the FALCON gravimetric concentrator undoubtedly indicates interesting results for a process that is not involved in the use of reagents, such as cyanidation in leaching.
