Ultrasonic beneficiation method

Abstract

The invention relates to an ultrasonic beneficiation method which comprises the following steps of: (1) adding water into a container containing crushed raw ore material until the water level is higher than the surface of the material; (2) inserting an ultrasonic vibration plate into the material water, and starting ultrasonic equipment to carry out ultrasonic treatment on the mineral aggregate; and (3) screening the mineral aggregate after the ultrasonic treatment so as to obtain tailings above the screen and concentrate below the screen, wherein if the obtained concentrate contains ferric magnetic minerals, a magnetic separator is used for separating the ferric magnetic minerals so as to further improve the target mineral concentrate grade and simultaneously obtain iron concentrate. The ultrasonic beneficiation method provided by the invention has an optimal effect on treating quartz type weathered sand tin ore. In the invention, the ultrasonic treatment is adopted as main operation aided with few routine works of screening, filtering and magnetic separation, process flows are short, works are few, the operation is relatively simple, target minerals can be quickly enriched, a large number of tailings can be eliminated simultaneously, and the obtained concentrate has the advantages of high enrichment ratio, large treatment capacity, low production cost, no adoption of beneficiation reagents and no pollution on the ambient environment, thus the beneficiation method provided by the invention is a new environment-friendly high-efficiency beneficiation method.

Description

technical field [0001] The invention relates to a new mineral separation method, an ultrasonic mineral separation method. Background technique [0002] The current four major beneficiation methods of gravity, magnetic, floating and electric are generally physical methods, which are essentially the separation of phases (minerals) and phases. Gravity separation is achieved by the density difference of the phases, and flotation is separated by the hydrophobicity difference between the phases. Separation, magnetic separation is separated according to the magnetic difference of the phase, while electric separation is separated according to the conductivity difference of the phase. These beneficiation methods, especially the three methods of heavy maglev are frequently used in production practice, and most of the beneficiation products in the world come from these three methods. There are many kinds of minerals in the world, and the purpose of people's beneficiation is nothing mo...
