Abstract

The invention discloses a mixing and separation system and method based on fluid enhancement. The system and method are suitable for separation of minerals. The system comprises a forced mixing and tempering system, a turbulence mineralization reaction system, a circulation flotation separation system and a centrifugal flotation separation system; the forced mixing and tempering system and a forced mixing and tempering device are connected and connected with the turbulence mineralization reaction system through a pipeline, and the turbulence mineralization reaction system is connected with thecirculation flotation separation system through a pipeline; the bottom of the circulation flotation separation system is connected with the forced mixing and tempering device through a pipeline, andthe circulating flotation separation system is connected with the centrifugal flotation separation system through a pipeline; the centrifugal flotation separation system is connected with the circulation flotation separation system through a pipeline. The method is simple in step and good in using effect; due to the reasonable design of the structure of a mixing and separation device and the mixing and separation fluid flow process and the reasonable design of local ore pulp circulation and system ore pulp circulation, the mixing and separation efficiency and capacity of mineral particles which have difficulty in flotation are improved.

Description

technical field [0001] The invention relates to a fluid-intensified mixing and separation system and method, and is especially suitable for the fluid-intensified mixing and separating system and method used for separating mineral particles or coal slime in coal mine processing. Background technique [0002] The mineral flotation process is a typical flow process, involving the adsorption of particles and chemicals, the mineralization of particles and air bubbles, and the separation of mineralized air bubbles. Its essence is a mixing and separation process, and the role of fluid runs through it all the time. With the ore depletion and the refinement of the separation scale, in addition to the technology and chemicals, the influence of the beneficiation process (or hydrodynamic process) is increasingly apparent. While flotation requires dosing, it also requires energy input. The more difficult the ore is to sort, the finer the particle size, and the greater the energy require...

AI Technical Summary

Problems solved by technology

The more difficult the ore is to sort, the finer the particle size, and the greater the energy required, which requires continuous strengthening of the energy injection during the sorting process. However, there is still a lack of research and related technologies that systematically strengthen the mineral mixing and separation process from the perspective of fluid flow. , such as the response mechanism of particles, agents, and air bubbles to the fluid environment, and the interaction between particles, air bubbles, and agents in different fluid environments, etc., specifically related to the traditional pulping process before flotation, flotation mineralization process, flotation separation process etc.
