METHOD FOR SEPARATION OF NANO- AND MICRO-SIZED PARTICLES WHEN ENRICHING MINERAL RESOURCES

摘要

The present invention relates to the field of mineral processing. A method for separating dust particles during mineral processing using a gas separator is proposed, including the stage of separating particles by size in an air (gas) flow. At the same time, dust is separated, in which the particles have nano- and micro-sizes, by coagulation of hydrophilic particles in a wet gas (air) stream due to the fact that hydrophilic particles are combined in a wet gas (air) stream, which leads to an increase in their weight and the formation of large conglomerates of these particles, which fall into the hopper with large particles, and the hydrophobic particles rise up. After separation of hydrophobic (lyophobic) and hydrophilic (lyophilic) particles, the excess hydrophobic (lyophobic) component is burned. The method makes it possible to separate micro- and nanoparticles according to their surface properties, which are practically not separated with conventional methods of concentration (flotation in an impeller flotation machine, gravity concentration in suspension).
