Partition flotation system

Abstract

The invention relates to the technical field of mineral flotation technology, specifically to a partition flotation system. The system comprises a flotation cell and a mixed slurry injection pipe. Anoutput port of the mixed slurry injection pipe horizontally penetrates through the cell wall of the flotation cell; more than one vertical partition is arranged at the bottom of the flotation cell, and the arrangement height of the vertical partition is lower than the height of the output port of the mixed slurry injection pipe; the board of the vertical partition is vertical to the spraying direction of the mixed slurry; a bubble generator tube used for inputting bubbles into corresponding sedimentation zone is arranged at the bottom of each sedimentation zone, and the aperture of an air outlet at each bubble generator tube is gradually reduced; and a discharge port used for outputting settled mineral particles of the current sedimentation zone is arranged at the bottom of the flotation cell of each sedimentation zone. The system of the invention has the advantages of compact structure, high flotation efficiency and good flotation effect, can increase flotation output while guaranteeing flotation quality, and is suitable for industrial operation.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a partition flotation system. Background technique [0002] Flotation is the most important interface separation method, and it has been widely used in the fields of separation flotation of polymetallic ores, comprehensive utilization of complex ores, iron ore flotation, and non-metallic ores. The theoretical basis of various flotation processes is roughly the same, that is, due to the hydrophobic characteristics of the surface of the ore particles or the hydrophobic (air-friendly or oil) characteristics obtained after the action of the flotation agent, the ore particles will be in liquid-gas or water-oil. Agglomeration occurs at the interface. At present, the most widely used method is the froth flotation method, which includes the following processes: 1) After the ore is crushed and ground, various minerals are dissociated into monomer particles, and the particle siz...

Problems solved by technology

The mechanical agitation flotation machine has been used for the longest time. It has a history of nearly a hundred years from ore dressing to coal dressing. It can provide a turbulent environment for the flotation tank, but the disadvantages are high energy consumption and large maintenance

The non-mechanical stirring flotation machine, also known as the inflatable flotation machine, uses a pump to provide energy for the pulp, and absorbs enough air through the jet flow and collision of the pulp. The disadvantage is that it needs a matching pump and consumes a lot of energy.

At the same time, because the non-mechanical agitation flotation machine needs to ensure sufficient ore flow and suction volume, the flow field in the flotation tank is often excessively turbulent, which will cause the mineralized particles to fall off during the flotation process, thereby affecting the flotation process. selection effect
