An Innovative Process for Comprehensive Utilisation of Clay-Vanadium Ores
An Innovative Process for Comprehensive Utilisation of Clay-Vanadium Ores By adopting conventional processing technologies such as flotation, gravity concentration, and magnetic separation, it is difficult to enrich vanadium mineral effectively. At present, vanadium extraction process usually has not the mineral processing enrichment procedure, but rather uses direct hydrometallurgical process: roasting - leaching - precipitating vanadium for obtaining high quality V2O5 product. But it results in problems, for instance, high consume of auxiliary materials like acid and alkali, serious pollution and high cost of vanadium extraction. In the project study on the ore of a certain clay vanadium mineral, by adopting the test process: scrubbing raw ore with reagents added in - dispersing and segregating with reagents - grading enrichment, vanadium concentrate product with higher grade was made by virtue of reagent's selective inhibiting, and the purpose of upgrading the raw material used for vanadium extraction with hydrometallurgical process is achieved._x000D_
The process technology obtained from project study features simple process structure, low equipment investment, low cost of mineral processing and pollution-free to environment. It provides high efficient and practical technology for the comprehensive utilisation of clay vanadium mineral, and has a prominent prospect for its popularisation and application.
