Abstract:
     The bauxite normal-floatation concentrate three-phase foam defoaming method relates to a floatation concentrate dehydration three-phase foam defoaming method in the mireral separation process, in particular, it relates to a three-phase foam defoaming method for diaspore normal-floatation concentrate dehydration in the floatation process adopting diaspore type bauxite as raw material. Said method is characterized by that the three-phase foam in the conventional settling dehydration can be led out from settling dehydration equipment, then water is added and diluted to make the dry mineral mass concentration be 10%-20%, finally the flocculating agent can be added to make its granules be flocculated and settled so as to implement defoaming effect. Said flocculating agent is anionic polyacnrylamide, and its molecular weight is 2000000-8000000, its optimum value is 2000000-4000000.
