Zinc oxide ore beneficiation production line for the extraction of zinc oxide is better by the "boiler gas dry method" method.

The flotation separation of gangue minerals containing calcium, magnesium, iron, etc., such as calcite, dolomite and limonite, is particularly difficult due to the interaction of the dissolved components with the surface of the mineral. At present, most of the flotation of zinc oxide ore uses a flotation flotation process, in which lead oxide is mainly used after flocculation and addition of xanthate flotation, while zinc oxide is mainly recovered by heating vulcanization, copper sulfate activation and then yellowing flotation. Or after vulcanization, it is floated with a fatty amine (primary amine).
