The objective of the thesis was to determine the efficient recovery of ounces of gold from the rubble of the leach pad, in order to increase production in a mining company in La Libertad due to the shortage of high-grade oxidized ore. To achieve the annual goal, it was evaluated to recover gold from the inventory of the pad, which contains this type of leached mineral (rubbles). The average grade was 1,26 g/t gold, with a recovery rate of 74,12%, estimating 19472,97 recoverable ounces. The heap leaching process parameters were also optimized. Additional gold recovery from 651264 tons of gravel was planned by leaching with cyanide solution. Metallurgical tests in columns showed recovery rates of 74,12% for gold, an average solution with 0,18 g/m³ of gold was obtained after percolation. An average of an additional 19472,97 ounces were recovered, significantly increasing production, with a total value of $3991588,5 at a price of $2050 per ounce of gold. The project required an investment of $786906,74 and shows an NPV (Net Present Value) of $24195125 and an IRR (Internal Rate of Return) of 54,43%, supporting its economic viability.
