Abstract:
     The invention discloses a flotation desiliconisation method of low-grade bauxite with ore grinding, agent paste mixing and floating courses, which is characterized by the following: mixing bauxite Baeyer stripping condensed water and ore dressing backwater as the floatation water according to stripping condensed water: fine ore backwater: tailing backwater=0.5-1.5: 4-6: 1.5-2.5; adding modifying agent, disperser and collector to float the low-grade bauxite of 4-6 A/S ratio, wherein the soda quantity scale of modifying agent is 1000-3000 g/ton; the hexametaphosphate quantity scale of disperser is 5-100 g/ton; the quantity scale of collector is 300-1000 g/ton. The invention improves the sorting property between hydraulic aluminum and silicon vein mineral, which reduces the agent consumption.
