Abstract

The invention relates to a method for extracting copper ions through ultrasonic wave channelization, and belongs to the technical field of hydrometallurgy. Feed liquid containing the copper ions and the organic phase of an extraction agent are pumped into extraction pipelines of extraction pipeline reactors for obtaining the loaded organic phase, and the extraction pipeline reactors are connected in series for carrying out multi-stage counter current extraction in the extraction process; after extraction is completed, the obtained loaded organic phase and a back extraction solution are pumped into the extraction pipelines of the extraction pipeline reactors for obtaining copper-bearing pregnant solutions through back extraction, and the extraction pipeline reactors are connected in series for carrying out multi-stage counter current back extraction in the back extraction process. According to the method, the feed liquid and the organic phase have the advantages that the contact area is large in a small pipeline and the mass transfer velocity is high, the strong cavitation effect, the mechanical vibration effect and the disturbance effect of ultrasonic waves are fully utilized, and therefore the mass transfer efficiency is improved, the extraction time and the back extraction time are shortened, the production cost is lowered, and the safety of the extraction process is improved.

Description

technical field [0001] The invention relates to a method for ultrasonic pipeline extraction of copper ions, which belongs to the technical field of hydrometallurgy. Background technique [0002] Extraction is to use the different solubility of the components in the system to separate the mixture, that is, to use the difference in solubility or distribution coefficient of the substance in two immiscible (or slightly soluble) solvents to realize the separation of components mass transfer process. Extraction operation is widely used in chemical, metallurgy, food and other industries. [0003] Extraction equipment is a kind of mass transfer equipment used for extraction operation, which can realize the separation of components contained in the feed liquid. According to the equipment structure, it is divided into mixing clarifier and centrifugal extractor. Most of these traditional extractors have an open design, and a large amount of extractant will volatilize during the extra...
