Abstract

The invention discloses a flotation column which comprises a flotation column body (5) and a bubble generator (4), wherein one end of a spiral pipeline (3) is connected with a feed opening (1), an air inlet (2) is arranged beside the feed opening (1), the other end of the spiral pipeline (3) is connected with the upper part of the flotation column body (5), the bubble generator (4) is connected with the lower end of the flotation column body (5) by adopting an external inserting mode, and both the air inlet (2) and the bubble generator (4) are connected with an air pump (6). An ore slurry can be fully sheared and mineralized by the flotation column by utilizing the spiral pipeline, the generated bubbles are superfine and have better dispersion effect, and the flotation column has the characteristics of simple structure, stable operation, difficult blockage, good mineralization effect and the like, can be suitable for floating a plurality of metals or nonmetals, is a new generation of high-efficiency flotation column and can be applied to multiple fields of metal mines, coal, environmental protection and the like.

Description

technical field

[0001] The invention relates to a flotation column, in particular to a flotation column with a spiral pipeline and a magnetic bubble generator. Background technique

[0002] At present, the general flotation column uses the bubbles generated by the bubble generator to mineralize inside the flotation column. In this way, the nature and dispersion of the bubbles generated by the bubble generator determine the good mineralization effect inside the flotation column. Bad, it is easy to cause uneven mineralization and insufficient flotation time. However, for the mineralization at the downcomer, the flotation column using a self-priming bubble generator needs the negative pressure generated by the high-speed slurry due to the inhaled air mineralization process, so the energy consumption on the feed pump is relatively large, which restricts the bottleneck more obvious. The bubble generator in the flotation column is widely used in metal and non-metal mines, metall...
