SUMMARY:

Mineral processing generates a high volume of tailings or residues, usually deposited in dams. This form of waste disposal can have high costs, environmental and social impacts and risk situations. In view of this, mining companies have been exploring and developing alternatives and new techniques to take advantage of the waste from ore processing, trying to reduce damage, disposal in the environment and waste of materials. Therefore, the objective of this work is to study the feasibility of using waste from the extraction and processing of phosphate in the incorporation of the formulation of soil-cement bricks, combining low cost and sustainability. With this, in addition to an environmentally correct destination for the tailings, it is expected to provide low-cost material to stimulate new business in the community impacted by the mining activity. And, to make this study viable, the characterization of the materials was carried out and later determination of the traces for the manufacture of the soil-cement brick. The characterization of the samples is essential for the development of the work because there may be variations in the mineralogical composition, granulometry and chemical composition. After manufacturing the bricks, characterization and classification tests will be carried out. Finally, it is expected that the brick studied demonstrates to have characteristics within the current norms for the subject and that they are compatible with the bricks commonly supplied in the market.
