At present, the development of mining contemplates aspects related to the need to find alternative reuse of tailings without affecting the social and environmental interests, and is initiative of mining companies under guidelines established, one of these processes shown that the flotation process polymetallic ores in a single mine produces approximately 25000 Ton / day and become part of the tailings problems of mining operations as allow leaching of toxic components (Hg, CN, ADR, etc.); that pollute soil and water; and consequently adversely affect the health of the workers and the surrounding population. In this regard the need to formulate solutions arises against this kind of existing environmental problems; thereby increasing the treatment of this material generating lower costs and increase interest in these mining operations. In this paper the characterization of the material and a method for manufacturing tiles are made from tailings from mining-scale plants, in order to neutralize the cyanide with hydrogen peroxide and sodium hypochlorite and grinding processes, homogenization, molded and dried, whose compact construction aggregate states determine a value added; composition results achieved in reducing the content of total cyanide 2 gr to 0.09 gr, obtaining a tile in a 95.5% free of cyanide.
