New flotation technology of Bosite low-grade zinc oxide ore, leaching technology of low-grade zinc sulfide ore
Zinc ore beneficiation equipment, flotation zinc ore equipment, zinc oxide ore washing technology
Zinc ore according to its The minerals contained are different and divided into sulfide ores and oxide ores. Due to the increasing depletion of sulfide ores, the development of zinc oxide ores has gradually attracted people's attention. The flotation separation of zinc oxide minerals and gangue minerals containing calcium, magnesium, iron, etc. at room temperature has always been a difficult problem. Due to the interaction between dissolved components and the mineral surface, resulting in mineral surface transformation, the flotation separation of zinc oxide minerals from calcite, dolomite, limonite and other gangue minerals containing calcium, magnesium, iron, etc. is particularly difficult.
At present, zinc ore beneficiation equipment, zinc ore flotation equipment, and zinc oxide ore washing technology mostly use sulfide flotation process. The lead oxide is mainly flotated by adding xanthate after sulfide, while the recovery of zinc oxide is mainly It adopts heating vulcanization, copper activation and then flotation with xanthate or flotation with aliphatic amine (primary amine) after vulcanization.
Since the amine flotation of zinc oxide ore is relatively sensitive to slime and soluble salts, although a lot of research has been done at home and abroad on zinc ore beneficiation equipment, zinc ore flotation equipment, and zinc oxide ore washing technology. Research and practice have still failed to solve the problems of low selection index of zinc oxide ore, complex process flow and chemical varieties, and high cost.
Therefore, it is a very meaningful research direction to use the simplest possible flotation process, conventional chemicals, and economical and effective flotation of zinc oxide ore.
