Turbulent flow regulating and controlling external particle fluidized bed mineralizing and floating device uniform in turbulence degree

Abstract

The invention discloses a turbulent flow regulating and controlling external particle fluidized bed uniform in turbulence degree and belongs to a mineral separation device. The device comprises a column floating area, a concentrate overflow groove in the upper portion of the column floating area and a middling ore circulating port outside the column floating area; the lower portion of the column floating area is provided with a gas and liquid mixing area; a fluidized bed mineralizing and floating area is arranged between the column floating area and the gas and liquid mixing area; the fluidized bed mineralizing and floating area is provided with a mineralizing area 1, a mineralizing area 2,... and a mineralizing area n; and the interiors of the mineralizing area 1, the mineralizing area 2,...and the mineralizing area n are filled with turbulent flow regulating and controlling particles. According to the turbulent flow regulating and controlling external particle fluidized bed uniform in turbulence degree, mineralizing and floating are totally separated, and are different from current integration of mineralizing and floating; the mineralizing time can be achieved by adjusting the mineralizing area segment number of the fluidized bed mineralizing and floating area, and therefore the kinetic energy utilizing efficiency is very high; the energy dissipating rate is high, the bubble size balance and stable retention of high-pressure gas are guaranteed, and the floating recovery rate is increased; and upper, middle and lower mineralizing fluidized bed layers are provided with different turbulence degrees, and the mineralizing efficiency is high.

Description

technical field [0001] The invention relates to a mineral separation device, in particular to a mineralization flotation equipment with uniform turbulent flow regulation and particle fluidized bed which is suitable for flotation. Background technique [0002] Flotation, especially froth flotation, is a method widely used in the separation of minerals and coal. It is estimated that more than 2 billion tons of minerals and coal are disposed of annually. Therefore, the reduction of flotation efficiency will cause a lot of resource waste and economic loss, and it is urgent to improve the flotation production efficiency and understand the flotation process in depth. With the depletion of high-quality mineral resources, low-grade, fine-grained and complex refractory minerals are faced with being unable to be mined and utilized due to high power consumption in the grinding and flotation process and high separation and recovery costs. Therefore, reducing the power consumption of t...
