The invention provides a mineralization-flotation separation column sorting device and method, which are applicable to ore processing. The mineralization-flotation separation column sorting device comprises a stirring barrel, a pump, a bubble generator, a mineralization chamber, a flocculation elimination pipe, a flotation column and an air compressor; after flotation ore slurry is mixed through slurry blending equipment and passes through the bubble generator, the ore slurry enters the cyclone mineralization chamber; the ore slurry which is rotated at a high speed and bubbles are subjected tohigh-strength turbulent flow collision and mineralized bubbles are formed; a large vortex of the mineralized bubbles are eliminated through the flocculation elimination pipe and then the mineralizedbubbles enter a flotation column static sorting region to finish static separation; a flotation assisting baffle plate is arranged at the bottom of the flotation column static separation region and the ore slurry is prevented from entering tailings due to short circuiting; ore grains which are not mineralized and desorbed are subjected to intensive recovery; low-ash clean coal is recycled and high-ash ores are discharged from a tailing opening. According to the mineralization-flotation separation column sorting device, the flotation and falling probability of low-ash coarse grains is effectively reduced and the equipment processing capability is great; the device has strong adaptability on different coal properties, low production and operation cost and is convenient to mount and operate;the quantity and quality of clean coal products are wholly improved.
Description
technical field [0001] The invention relates to a column separation device and method for mineralization-flotation separation, and is especially suitable for the column separation device and method for mineralization-flotation separation used in mineral processing technology in the field of mineral flotation technology. Background technique [0002] With the increase of the proportion of mechanized coal mining and the decline of the quality of the washed coal, the coal slime presents the characteristics of fineness, high ash, and large content of intergrowth, which are difficult to separate. It is difficult to achieve synergy, and there is an urgent need for key technologies and equipment for high-efficiency separation of coal slime flotation. With the advancement of coal slime separation technology, new types of equipment continue to appear, but there is still a big gap between the separation effect and high-efficiency separation. As the leading separation equipment of coa...
