Iron ore concentration plants by flotation use a large volume of water. A large amount of this water, containing residual reagents and colloids, is recirculated for different processes, such as sieving, desliming, and flotation. However, the physicochemical composition of water can impact process efficiency. Then, the objective is to reduce the consumption of reagents and new water by developing a process route for water reuse and/or disposal according to environmental legislation.
