The exploitation of slate generates a large amount of waste, mainly in the extraction and processing stages, giving rise to environmental liabilities. In order to minimize this impact, this work aimed to reuse the slate waste to produce mineral fillers, which are widely used in the manufacture of composite materials. With this purpose, the slate residue was collected from the waste pile of a mining company near the city of Pompéu / MG, being technologically characterized and also by comminution processes for granulometry adequacy. Analyzing the results, it was verified that this waste meets the specifications to be used as potential mineral filler, due to the high percentage of silica and alumina and granulometry below 0.045 mm after milling, showing similar characteristics to those already used in the market. In this way, this possible reuse can contribute significantly to solid waste management in mining and minimization of environmental impacts.Downloads
