Problems solved by technology

[0010] But at the same time, it is also found that the purification method of "one-pot cooking" proposed by this patent is not stable enough for ultrasonic irradiation, which is not conducive to giving full play to the strengthening effect of ultrasonic waves, so that the industrialization effect is not ideal when the laboratory effect is good.

Embodiment 1

[0035] pass figure 1 It can be seen that the present invention is an ultrasonic purification method for wet zinc metallurgy. In the ultrasonic purification device for wet zinc metallurgy, the ultrasonic sound field generated by ultrasonic waves is used to perform irreversible ultrasonic irradiation on the wet zinc metallurgy solution to be purified, so that the liquid after the purification reaction The concentration of ionic impurity tends to decrease irreversibly, so as to achieve the purpose of impurity removal. The ultrasonic sound field at least includes a frequency of 15-28kHz and a sound intensity of 0.5-5w / cm 2 ultrasonic sound field. The hydrometallurgical solution to be purified is the solution after leaching of zinc ore powder containing copper, cadmium, cobalt, and nickel ionic impurities (commonly known as the supernatant), and the concentration range of the ionic impurities includes at least: copper ≤2000mg / L and (or) cadmium ≤2000mg / L and (or) cobalt ≤200mg / L ...

Abstract

The invention relates to an ultrasonic purification method for wet zinc smelting, and a device and application thereof. In the ultrasonic purification device for wet zinc smelting, an ultrasonic field produced by ultrasonic waves is adopted to carry out irreversible ultrasonic irradiation to wet zinc smelting solution to be purified, which causes the concentration of ionic impurities to be decreased irreversibly so as to realize the purpose of removing impurities. The application of the method can realize quick purification of required standards, greatly decreases the consumption of zinc powder, directly produces high-quality copper residue, cadmium residue and cobalt residue, and also is applicable to the treatment of the copper-cadmium residue and cobalt-nickel residue produced by wet zinc smelting purification previously.

Description

Technical field [0001] The invention relates to a wet zinc metallurgy purification method and device, in particular to a wet zinc metallurgy ultrasonic purification method and device under the condition of using ultrasonic waves to improve the activity of zinc powder, and belongs to the technical field of purification. Background technique [0002] In zinc hydrometallurgy, since the zinc sulfate solution produced by leaching zinc ore powder contains copper, cadmium, cobalt, nickel and other impurities, it is necessary to treat the zinc sulfate solution for leaching zinc ore powder. At present, zinc powder is generally used as a reducing agent to remove various impurities in zinc sulfate solution, which is a general purification process in the zinc hydrometallurgy process. However, the current general-purpose purification process consumes high zinc powder, accounting for 3-5% of the output of electrolytic zinc. Moreover, energy consumption has increased substantially, which ...
