Abstract:
     The invention relates the bauxite mineral concentration method. The method comprises the following steps: separating aluminum and iron from high ferro bauxite with magnetic concentration, bruising ore to 0-25mm, selecting the ore particles whose granularity is 0.074, using water as transmission medium, roughing separating the ore pulp with cobber to get roughing separation iron concentrate and roughing separation aluminum concentrate; refining them with cobber to get classification iron concentrate and classification tailings, scavenging; desliming the aluminum concentrate and getting the aluminum oxide concentrate; the classification iron concentrate carried out reverse flotation with anion to reclaim iron, after grinding, and the granularity being -400 mesh, adding modifying agent, dispersing agent, inhibiting agent and collector to carry out the first reverse flotation, then carrying out the second reverse flotation to get the rich iron concentrate and tailings.
