In this research work, the removal of sulfur compounds from the filtration water of the Quebrada Honda tailings deposit of the UTE Toquepala - Tacna with natural Zeolite of the clinoptilolite type was evaluated. The natural zeolite (clinoptilolite) was used in two stages: natural un-activated zeolite and natural zeolite activated with NaCl; the chemical structure of the natural zeolite (clinoptilolite) was determined by infrared (IR) spectroscopy. filtration water samples were taken from the Quebrada Honda tailings deposit, from July 2018 to December 2018, they were subjected to 6 treatments varying the weight of the natural zeolite (clinoptilolite) and the pH, obtaining a maximum removal of 81 % at pH 9 with 1400 grams of natural zeolite; the adsorption capacity 23.53 mg SO4-2 / g with 1400 g of natural zeolite at pH 9, the Langmuir isotherm shows coefficients of 23.53 mg / g; porosity of 28.23% and surface area 24.9 m2 / g. The concentration of sulfur compounds was lowered from 1943 mg / l to 77 mg / l, complying with the Environmental Quality Standards for water category 3. It is concluded that the natural zeolite of the clinoptilolite type offers properties that allow the elimination of sulfur compounds dissolved in water.
