Abstract

The invention discloses an ore pulp defoaming method and an ore pulp defoaming device. The method and the device are suitable for most defoaming technical fields of mining industry, chemical industryand the like, and are mainly used for defoaming mineralized foam products and conveying ore pulp in the flotation process. The biggest innovation point of the defoaming device is that a physical modeis utilized to carry out extrusion and shearing defoaming and impact force defoaming of a gas-water mixture to reduce the water consumption and avoid use of chemical agents, so compared with traditional defoaming devices and methods, the device and the method of the invention have the advantages of good environment-friendly effect, evenness in mixing of the ore pulp, stable ore pulp indexes, gooddefoaming effect, good flow conductivity, and reduction of the workload of subsequent operation.

Description

technical field [0001] The invention relates to most defoaming technical fields such as mining and chemical industry, especially the defoaming technical field of mineralized foam products of flotation ore pulp. Background technique [0002] With the increasing depletion of rich ore and easy-to-separate mineral resources, "poor, fine, miscellaneous" and other refractory ores have become the main mineral resources. Flotation is one of the most widely used separation methods in the field of mineral separation. Mineral flotation needs to be completed at the solid-liquid-gas three-phase interface. The addition of flotation agents such as amine collectors and excessive foaming agents makes the over-stable mineralized foam produced during the flotation process have high viscosity and poor fluidity. Good stability and other characteristics, resulting in difficult defoaming of foam products, tank turnover and pipeline blockage, etc., which seriously affect the post-processing process...
