Process for producing an aritificial aggregate from mining waste, artificial aggregate, concrete composition and use
The present invention relates to a process for producing an artificial aggregate from ore mining dam waste. The iron ore sandy tailings are mixed with a binder and, by means of a process of mixing and pelleting, form the artificial aggregate. The artificial aggregate thereby produced has a spheroidal shape, is coarse, has a rough surface and a colour ranging from pink to dark red. Said artificial aggregate can be used as a replacement for a natural aggregate, and can be used for manufacturing stronger concrete, for the base and subbase of roads, as a decorative element for gardens and flower beds, and is also a means for storing ore mining dam waste in the form of pellets, adding value to said waste and reducing the impact of mining on the environment.
