Extraction equipment for hydrometallurgical vanadium extraction from tailings. In the process of hydrometallurgical production and processing, a large amount of tailings will be produced, and some of the tailings contain metallic vanadium. If it is not processed and recycled, it will be a waste of resources.
Equipment for Extracting Vanadium from Tailings
Currently, the extraction equipment used is mainly CWL-M centrifugal extractor. The new CWL series centrifugal extractor independently developed and produced by Zhengzhou Tiei Extraction Technology is widely used in the extraction of metal elements in the field of hydrometallurgy. Metals such as nickel, cobalt, copper, zinc, vanadium, lithium, etc. can be extracted.
In the past, hydrometallurgical extraction equipment mainly used mixer settler. With the continuous development of technology, traditional extraction equipment such as mixer settlers relying on natural gravity stratification can no longer meet production needs. Therefore, more and more companies use centrifugal extractors instead of mixer settlers to extract metal elements.
Methods for Extracting Vanadium from Tailings
Metallic vanadium is a silver-gray metal with a very high melting point. It belongs to the category of rare metals with high melting points. It is often called refractory metals together with niobium, tantalum, tungsten and molybdenum. Vanadium is ductile, hard, non-magnetic, not oxidized in the air, and soluble in hydrofluoric acid, nitric acid and aqua regia.
There are several common methods for extracting vanadium from tailings, but the most commonly used one is solvent extraction. Among them, the multi-stage solvent extraction using the centrifugal extractor has a significant effect.
In the specific operation of hydrometallurgical extraction vanadium from tailings, the ore is leached, and then the ore leachate and the extractant are injected into the centrifugal extractor in a certain proportion. With the help of the rotation of the drum, the two phases are quickly mixed and dispersed through the turbine disc and impeller, and the two-phase solution is fully transferred to complete the mixing and mass transfer process. The mixed liquid is then separated by the centrifugal force of the drum and discharged from the machine body.
