Embodiment Construction

[0018] like figure 1 As shown, the flotation column 1 includes an inlet for feeding, an ore discharge outlet at the bottom (no reference numerals are given), the bottom of the flotation column has a middling collection part 7, and the middling collection part 7 collects the middling slurry of the flotation column After collection and confluence, it is sent to the mode selection part 9 by the pump 8, and the mode selection part 9 is connected with the distributor 3, and the medium ore slurry enters each slurry return pipe evenly through the distribution of the distributor 3, and returns to the flotation column 1, and the slurry is returned The interface between the tube and the flotation column 1 is located at the upper part of the middling ore collection part 7 .

[0019] from figure 2 It can be seen from the figure that the feed end 15 of the mode selection part 9 is connected to the pump 8, and the discharge end 16 is connected to the distributor 3. The switching structure...

Abstract

The invention discloses a highly reliable floatation method. A mode selection part is adopted in the highly reliable floatation method. A switching structure is arranged in the mode selection part. The working state of the floatation pillar can be better monitored through the structure, blocking of a return pipe can be found and in addition, the floatation mode of the floatation pillar can be automatically switched to a non-middling circulation mode. Reliability of the floatation pillar is improved. A main control machine of the floatation pillar boosts and reduces pressure repeatedly by controlling the pumping pressure of a pump and impacts a blocked position. The floatation pillar can be used for carrying out floatation under either the first mode or the second mode, and therefore the blocked part is dealt with online.

Description

technical field [0001] The application relates to a flotation method, in particular to a method for switching between two sets of flotation systems to ensure flotation reliability. Background technique [0002] The flotation column is already a conventional equipment in the field of flotation. The flotation column usually has a middling circulation structure. The middling circulation structure will reinflate the insufficiently flotation middlings and return them to the flotation column. The existing middling circulation structure hopes to The pulp is distributed more evenly, so more slurry return pipes are used, but too many branches of the slurry return pipes lead to a smaller diameter of the pipes to adapt to the return volume of the middle ore, and the phenomenon of blockage of the return slurry pipes is inevitable. [0003] At present, there is no particularly effective technical solution to overcome the blockage of the slurry return pipe. First of all, it is difficult t...
