[0031] The fine mineral samples are two kinds of -0.074mm grain size coal slime from a mining area in Zhungeer Banner, Ordos City, Inner Mongolia Autonomous Region. 1 # Micro slime. The carrier particles are 0.5-0.25mm coal slime from a coal preparation plant in Etuokeqianqi, Ordos City, Inner Mongolia Autonomous Region. Table 1 is the industrial analysis results of 1# and 2#-0.074mm fine coal slime and carrier coal particles. The test adopts traditional direct flotation process, carrier flotation process and fine mineral separation process combined with cavitation pretreatment and carrier flotation to carry out flotation of -0.074mm particle size coal slime, and the tests are all carried out in the laboratory. figure 1 It is a schematic diagram of the fine mineral separation process combined with cavitation pretreatment and carrier flotation.
