Russian State Research Institute of the non-ferrous metal tank volume to a new generation of deep slot pillar 1 ~ 200m 3 inflatable flotation machine. Because the working efficiency of the flotation machine is mainly determined by the flotation machine structure and the gas dispersion method, the degree of aeration of the flotation machine and the distribution of bubbles of different sizes affect the flotation speed and flotation selectivity. Therefore, the structural design of the inflator has received attention. This column type air-filled flotation machine has the following operational and process advantages over the conventional flotation machine: the amount of metal used to manufacture the flotation machine is reduced by 50% to 66%, the equipment footprint is reduced by 50%, and the power consumption is reduced by 33%. 50%, the refined grade obtained is increased by 2% to 3%, and the recovery rate is increased by 0.3% to 3.0%. According to the results of development work and pilot inflatable flotation machine,俄罗斯米哈诺Boolean beneficiation Research and Design Institute in 1988 and the bulk flotation concentrate was featured in mixed copper and molybdenum ЖирекинÑк copper-molybdenum concentrator first application ФП-10 and ФП- 80 column inflatable flotation machine (Figure 1 and Figure 2). The industrial test results of the ФП-80 inflatable flotation machine show that it has many advantages over the mechanical agitating flotation machine and the aerated mechanical agitation flotation machine. It is reasonable to install a column type pneumatic flotation machine in the flotation plant.
This type of column type pneumatic flotation machine has a volume of 40 to 220 m 3 . The shape of the tank is circular, rectangular and elliptical and is made of steel, concrete, wood or other materials. The direction of the slurry and the movement of the bubble is a reasonable design of a variety of structures of the convection and downstream. Body-centered grilles can get bubbles of different sizes. The coil thick tube inflator has a long working life. 100 sets ФП column type flotation machine inflator obtained copper, molybdenum, lead zinc ore, gold, copper, zinc, bismuth, tungsten ore, iron ore, fluorite, barite ore flotation application.

The comparison test of the mechanical agitating flotation machine shows that when the copper grade of the concentrate is the same, the concentrate nickel grade of the gas-filled flotation machine is increased by 0.41%. When the copper recovery rate is similar, the nickel recovery rate of the gas-filled flotation machine is increased by 7.58%.
Demineral flotation of potash ore is carried out using a ФП-40 column type pneumatic flotation machine equipped with an airlift aerator. The mud removal index is better than the cyclone. The sandpaper KCI recovery rate increased by 8%.
Featured comparative tests performed on the crude concentrate by column apatite flotation machine and the inflator mechanical flotation machine, test results show that a selection of the inflator column index than the mechanical flotation machine flotation machine 3 The secondary selection index is even better. The P 2 0 5 grade of phosphate concentrate is increased by 0.5%, the recovery rate is increased by 15%, the loss of coarse particles in tailings is reduced, and the power consumption of flotation is greatly reduced.

The new ΚΦΜ type column flotation machine developed by the Ural Mihanopur Concentration Research and Design Institute consists of a jet inflator, a microbubble generator, a central tube, a discharge device and a foam collection tank. The flotation machine has two inflated zones, two slurry boiling zones and two in-tank product discharge zones. Rough selection and selection can be achieved simultaneously in one flotation machine. It has a large processing capacity, which is 3-4 times higher than the mechanical stirring flotation machine and the aerated stirring flotation machine, the floor space is reduced by 4/5, the power consumption is reduced by 80%, and the granularity of the flotation mineral is wide (1mm~lOμm). Operators are reduced by 30% to 40%. The ΚΦΜ type column flotation machine with a volume of 3.5-56 m 3 has been industrially used for flotation copper ore and cobalt- containing pyrite ore.
