ABSTRACT The influence of the concentration of sodium ethylenediaminetetraacetate (EDTA) and residence time on the recovery of copper in oxide mineral, from Salpo, freedom, was studied. The experimental study was carried out using effluent with different concentrations of EDTA as a function of stirring times at 60, 120 and 180 minutes, with an initial law of 3.73% copper. The result of the study of the use of EDTA concluded that the recovery of copper at 60 minutes and concentration of EDTA 0.10 M was 30.65% and as both variables increased, the removal also increased, so it was possible to obtain a recovery of 90.65% at 180 minutes and at an EDTA concentration of 0.15 M. The results are confirmed by analysis of variance for a confidence level of 95%. From this it is concluded that the recovery of copper as a function of the concentration of EDTA is F0 = 1124.711 is greater than F0.05, 2; 18 = 3.55, and the influence of residence time is F0 = 647.2694 is greater than F0 .05; 2; 18 = 3.55 and with the influence of EDTA concentration and residence time is F0 = 33.29 is greater than F0.05; 4; 18 = 2.93, obtained in a tabular manner. This confirms the acceptance of the alternative hypothesis, therefore, the influence of the concentration of EDTA and the time of residence individually and as a whole if they significantly affect the recovery of copper.
