In flotation, not only the minerals are required to dissociate sufficiently, but also the appropriate particle size is required. The ore is too thick. 9 Even if the mineral has been dissociated from the monomer, it will not float because it exceeds the buoyancy of the bubble. Different flotation size limit for minerals, such as sulphide minerals is usually 0.2-0.25 mm, 0.25-0.3 mm as the non-sulfide minerals, for some of the less dense non-metallic mineral, such as coal The upper limit of the granularity can also be increased. However, too fine a fine grain size (e.g., less than 0.01 mm) is also detrimental to flotation. Practice has proved that the flotation behavior of various granularities is poor (see Table 12.3.1). The data in the table indicates that different minerals have their optimal flotation particle size range. Too coarse (greater than 0.1 mm) and too fine (greater than 0.006 mm) are not conducive to flotation and the recovery is reduced. Timely measurement of the change of the graded overflow fineness can provide a basis for the grinding classification operation. In the case of no automatic measurement of particle size and automatic adjustment, rapid screening analysis can be generally used. The site shall be measured every 1 to 2 hours according to the regulations. If the fineness is not satisfactory, the operating conditions of the grinding and classifying equipment shall be changed in time, for example, adjusting the feeding speed of the mill.

Rate, classifier overflow concentration, grinding concentration, etc. Timely inspection of the particle size composition of flotation concentrates and tailings, can also find changes in grinding fineness, such as the increase in coarse-grained grade loss in tailings, the so-called "running rough", indicating that the grinding fineness is not enough, if the metal is mainly Loss at the fine-grain level indicates that it has been over-grinded and should be properly ground and reinforced. Both coarse and ultrafine (sludge) have many special physical and physicochemical properties, their flotation behavior and general grain size (0.001
