In the present study aimed to determine the influence of leaching time and concentration of sodium cyanide (NaCN) on the percentage of recovery of gold (Au) by stirring in pulp of a gold ore from Minera Danzig - Ancash, this mineral has an average grade of 18, 3 g Au / t in addition to 80% gold recovery using the method cyanidation. The objective is to determine the conditions that this mineral should be treated to obtain greater percentage gold recovery, and thus have greater economic profitability low costs. Therefore tests were done using a two-factor model having as variables study the concentration of sodium cyanide (3 levels): 1000 ppm, 3000 ppm and 5000 ppm and leaching time (4 levels): 6 h, 12 h, 24 h, 48 h with a total of 2 replicates for each combination of levels, resulting in a total of 24 samples. According to the analysis of variance, it shows that there is an influence between the interactions of the concentration of sodium cyanide and leaching time on the recovery of gold, thus demonstrating that the concentration of sodium cyanide and leaching time favors recoveries gold. Higher result are given to a leaching time 12 hours with 1000 ppm sodium cyanide concentration, showing 93.69% gold recovery average.
