(1) According to the nature of the ore (such as optionality, selected particle size, density, grade and pulp pH value), mechanical agitation may be used when the ore is easier to select and the required aeration amount is not large. Inflatable and agitated. When the coarse mineral crystal size, the choice of suitable coarse KYF type, BS-K-type flotation machine and CLF coarse flotation machine. When the ore is easy to select, the selected particle size is fine, the grade is high, and the pH value is low, the flotation column with large enrichment ratio is selected; (2) According to the scale of the plant, in general, large-scale concentrators should use large-scale flotation machines, and medium-sized and small-scale concentrators should use medium and small-sized flotation machines; (3) The selected operation is mainly to improve the concentrate grade. The flotation foam layer should be thinner in order to separate the gangue. It is not advisable to use a flotation machine with a large amount of aeration. Therefore, the flotation machine for selecting operations should be coarsely selected and selected. The operation flotation machine is different; (4) It is necessary to pay attention to the manufacturing quality of the flotation machine and the supply of spare parts and spare parts.
