Rejeitos de minério de ferro: uma avaliação de sua aplicação na construção civil

Abstract

The iron ore industry moves millions of tons of materials annually. In addition to products with high metallic content, large masses of waste are generated: waste rock and tailings. The tailings come from the mineral processing stage and require large areas for their disposal, whether in dams or tailings piles. Thus, the search for reusing these tailings in alternative markets has been a very relevant topic for today, aiming at reducing the socio-environmental impacts in the sector and generating revenue through the commercialization of these by-products. This work carried out in-depth bibliographic research that demonstrated the reuse of iron ore tailings in other sectors as an alternative with great potential for reducing socio-environmental impacts and promoting the circular economy in this sector. In addition, a connection was made between the main characteristics of these tailings and the standards of the civil construction sector, allowing a correlation between these sectors.
