Study of Ceramic Block Manufacture with the Addition of Waste from Iron Ore Extraction

Abstract: This work is intended to study the possibility of adding an amount of waste from iron mining in the ceramic mass. Clay and coal, from Vale do Paraiba, Sao Paulo, Brazil, were used in this research. These raw materials are used in the ceramic block manufacture. Clay and waste were analyzed by X-ray fluorescence and X-ray diffraction, particle size, differential thermal and thermogravimetric analysis. Liquid limit and plasticity index tests were performed in order to determine the amount of waste that which shou… Show more

“…The alternatives for utilization of these flotation tailings from the itabirite processing can be considered as a strategy for waste utilization and to minimize harmful effects in respect of environmental aspects, besides contributing to reducing the amount of tailings stored in the dams, apart from economic advantages of waste utilization [2]. There are many other existing reuse practices, for theses materials such as the manufacture of ceramics, use in pavements, and other applications [2][3][4]. In this work, use of these tailings as base sand for mold making in the foundry industry is investigated.…”
