ABSTRACT The main objective of this thesis is to determine the influence of the blending of minerals with silica alterations in percolation by leaching in laboratory tests in columns. In addition, determine at laboratory level the proportion of blending and% -200 mesh of minerals with alterations of massive silica, granular silica mixed with silica alunite; and its influence on the percolation of the cyanide solution. Also determine the proportion of blending of minerals more optimal to improve the percolation of cyanide solution. The experimental study was conducted using minerals from a mine located in the province of Lucanas, Ayacucho; where the domain of the silica alterations are alunite silica alterations, and this alteration is characterized because the gold is free in a matrix of thin silica alunite of low percolation. To this alteration of silica alunite SA the blending was performed in proportions with the compact granular silica SC and massive silica SM. The presence of the three alterations presented by the ore extracted from the mine in Lucanas, cause variations in the percolation that does not guarantee the permanence, constancy and sustainability of the Au law, for which it is necessary to standardize the blending of minerals and thus obtain more efficient and technological management of the mixture of minerals in the pad. The result of the study concluded that there is a significant influence of the blending of minerals with silica alterations in percolation by leaching. Likewise, it is concluded that the% granulometry - 200 mesh of the mineral blending of the alterations, is inversely proportional to the percolation; that is, at a lower% granulometry - 200 mesh of mineral blending, the higher the percolation ratio of the cyanide solution, making all blending proportions with silica alunite. It is also concluded that the most optimal blending ratio with silica alunite SA, consists of tests 6 and 9, which have acceptable percolation. That is to say if the silica alunite SA, is mixed with granular silica compact SGC, in 25% SA + 75% SGC, the percolation is increased to 1.87 m / day because the amount of fines provided by the mixture is 7.22 % 200 mesh If the silica alunite SA, is mixed with massive silica SM, in 25% SA + 75% SM, the percolation is increased to 1.90 m / day because the amount of fines provided by the mixture is 4.32% -200 tights. KEY WORDS: Alteration, alunite, argillic, blending, epithermal, percolation, silica.
