Embodiment 1

[0040] A specific embodiment of the present invention discloses a heavily oxidized coal flotation system, such as figure 1 As shown, it includes grinding equipment, coal slurry bucket 2, classification cyclone 3, slurry pump, mixing bucket 5, and flotation column 7.

[0041] The grinding equipment is used to pulverize the heavily oxidized coal to be sorted. The grinding equipment adopts a ball mill 1. The ball mill 1 is provided with a feeding port and a discharging port, and the feeding port is the oxidized coal feeding port 8. The coal slime bucket 2 is located below the ball mill 1, the feed inlet of the coal slime bucket 2 is connected to the discharge opening of the ball mill 1, and the discharge opening at the bottom of the coal slime bucket 2 and the feed opening of the grading cyclone 3 are on the pipeline. A first slurry pump 4 is provided. The classification cyclone 3 is located above the ball mill 1 and the mixing barrel 5, and the classification cyclone 3 is provi...

Embodiment 2

[0047] Another specific embodiment of the present invention discloses a flotation method for heavily oxidized coal. The flotation process is as follows figure 2 As shown, based on the heavily oxidized coal flotation system in Example 1, the separation process of "ultrafine grinding-hydrophobic flocculation-column flotation recovery" fundamentally solves the problem of poor surface hydrophobicity of oxidized coal and low efficiency of conventional flotation. The problem.

[0048] like figure 1 As shown, the heavily oxidized coal flotation system includes a ball mill 1 , a coal slurry bucket 2 , a classification cyclone 3 , a slurry pump, a mixing bucket 5 , and a flotation column 7 . The ball mill 1 is used to pulverize the heavily oxidized coal to be sorted, and the ball mill 1 is provided with a feeding port and a discharging port. The coal slime bucket 2 is located below the ball mill 1, the feed inlet of the coal slime bucket 2 is connected to the discharge opening of th...

Abstract

The invention relates to a heavily oxidized coal flotation system and a flotation method, belonging to the technical field of coal flotation, and solves the problem that the existing flotation method cannot recover fine-grained heavily oxidized coal. The heavily oxidized coal flotation system includes grinding equipment, coal slime buckets, classifying cyclones, slurry pumps, mixing tanks and flotation columns. Flotation" three links to realize the recovery of heavily oxidized coal. The invention realizes high-efficiency recovery of fine-grained heavily oxidized coal.

Description

technical field [0001] The invention relates to the technical field of coal separation, in particular to a heavily oxidized coal flotation system and a flotation method. Background technique [0002] my country is rich in coal resources, and the status of coal as the main energy source will not change in a short period of time. With the popularization of heavy medium coal preparation technology, the proportion of coal mining mechanization has increased, and the amount of fine-grained slime washed has increased sharply. [0003] Flotation, as the most effective means of sorting and upgrading fine-grained slime, realizes the selective separation between coal and gangue particles according to the different surface wettability, and the coal particles float up by adhering to the bubbles to form mineralized gas flocs. It becomes clean coal, while the hydrophilic mineral particles continue to stay in the slurry and are discharged with the tailings. For traditional coking coal and...
