Embodiment 1

[0023] Embodiment 1: A kind of ultrasonic vulcanization process method of copper oxide ore

[0024] The copper oxide ore has a particle size of -200 mesh and contains 1% copper. The conventional vulcanization process is adopted, using sodium sulfide as the vulcanizing agent. After vulcanization and flotation, the output copper concentrate contains 1% copper.

[0025] Under the above process conditions, increase the process conditions of ultrasonic irradiation to the solution. In the solution filled with copper oxide ore, an ultrasonic emitting device is installed. The ultrasonic emitting device emits ultrasonic waves when the copper oxide ore solution is vulcanized. The ore particles are impacted, and the ultrasonic impact is used to remove the surface coating of the copper oxide ore particles, so that the particles expose their own surface and accelerate the vulcanization process. The ultrasonic frequency is 15-200kHz, and the sound intensity is 0.5-200w / cm 2 , the ultrason...

Abstract

The present invention provides a method which utilizes ultrasonic to remove the surface cladding of particles, in particular to a method which utilizes ultrasonic to strike particles in a solution and remove the surface cladding of particles so as to expose the surface of particles. The ultrasonic is 15 to 200 kHz in frequency and 0.5 to 200w/cm< 2 > in acoustic intensity. The surface cladding of particles comprises the self surface cladding of particles and newly generated surface cladding of particles in the solution. The uses of the method include ultrasonic sulfuration process, ultrasonic floatation process, ultrasonic dipping process and ultrasonic purification process.

Description

technical field [0001] The invention relates to a method for removing the coating on the surface of particles in a solution, in particular to a method for removing the coating on the surface of granular substances in a solution by ultrasonic waves, and belongs to the field of separation technology. It can be widely used in wet mineral processing, hydrometallurgy, chemical process and other processes. Background technique [0002] In order to improve work efficiency, it is often necessary to remove the coating on the particle surface in the solution during the process of wet mineral processing and hydrometallurgy. Mechanical stirring is a method to remove the surface coating of particles in the solution. The application in the process is extremely common. Using mechanical stirring to remove the surface coating of particles in the solution can strengthen the effective contact between the particles and the solution, improve the kinetic diffusion process on the particle surface...
