Abstract

The invention relates to the technical field of mineral flotation, specifically to an eddy flow partition flotation machine. The flotation machine comprises a flotation cell and a rotary discharge pipe. the rotary discharge pipe can rotate around its axis; a first guiding conical surface and a second guiding conical surface are coaxially and fixedly connected at an output port of the rotary discharge pipe; the output port of the rotary discharge pipe is a radial discharge port, a discharge end of which is directed at the inner wall of the first guiding conical surface; a bonding post is arranged in the fit clearance between the first guiding conical surface and the second guiding conical surface; and a bubble generator tube is arranged at both the mineral grain blanking point of a walk-through passage and the mineral grain blanking point pointed by the large-diameter end of the second guiding conical surface. The collision efficiency between mineral grains and bubbles can be effectively improved, and finally the flotation efficiency and effect can be both greatly enhanced.

Description

technical field

[0001] The invention relates to the technical field of mineral flotation, in particular to a swirling partition flotation machine. 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. Currently 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 individual ore particles, and t...
