Abstract

Abstract

Bauxite-type vanadium deposit in north sichuan is a newly discovered type of vanadium deposit. Through the study of process mineralogy and selectivity of vanadium, it is found that vanadium has two kinds of occurrence states: The main is an independent mineral in the form of vanadite, and the other is in the form of isomorphism in sericite and illite. The experimental study on the washability of vanadium ore shows that the bauxite type vanadium ore is economic. The valuable element vanadium and molybdenum in ore can be recovered effectively by the combined flowsheet of “ Recovery of sulfide by heavy separation- recovery of vanadium and molybdenum from tailings by roasting in air and alkaline leaching-Recovery of clay ore by leaching residue”. The associated pyrite and clay minerals in ore are utilized synthetically. After the test, the slag leaching rate of vanadium is 74.42%, the liquid leaching rate of vanadium is 75.97%, the slag leaching rate of molybdenum is 88.77%, the liquid leaching rate of molybdenum is 91.00%.
