The use of flotation process for the mineral enrichment is increasing to satisfy the client and to match his evolving requirements. The consumption mode of reagent and energies greatly impacts the global cost of mineral enrichment by flotation, and is a determinant factor in the overall performance. To improve the quality of products, we developed new wash and flotation processes of minerals. Their enrichment knows a big development and arouses a particular interest, which is motivated by the increasing product’s demand and by the need to handle the enrichment of minerals that cannot be done by the conventional treatment processes.
