It is generally believed that vanadium in carbonaceous shale and stone coal is mainly in a dispersed state, and it is impossible to select an independent phase by physical beneficiation . At present, vanadium is extracted from stone coal by the flat kiln sodium roasting method. Since the manufacturers are mostly township enterprises, the production scale is small and irregular, the conversion rate of vanadium and the total recovery rate are low, and the harmful components such as chlorine and hydrogen chloride contained in the flue gas are difficult to handle, and the pollution caused by the environment is serious, and many irregularities are caused. The small enterprises have been banned, so their total production scale has not been large, and the output is not high, accounting for about 5% of the national vanadium production, and most of them are chemical products. But recently, Guizhou Zhenyuan County 101 geological team found a nearly 80 million tons of vanadium ore, vanadium pentoxide metal volume of more than 60 tons independent multi-layered vanadium deposit, which is the largest independent vanadium deposits so far discovered in Guizhou. The Guizhou 101 Geological Team discovered this mine during the 1:5 million lead , zinc and silver geochemical anomalies. It is confirmed by further geological exploration that the vanadium deposit is located in the transition zone between the southwestern margin of the Yangtze quasi-station and the Jiangnan orogenic belt. The ore deposit is layered in black siliceous rock and carbonaceous shale interbedded strata. In the middle, there are 3 layers, which are independent vanadium deposits, and are associated with rare metals such as uranium , platinum and palladium . The discovery of this independent vanadium ore has changed the understanding that most people think that vanadium exists in the associated state, and only a single layer, which is of great significance for further correct evaluation and search for this type of vanadium ore. 2. vanadium mainly isomorphism occur in the iron ore of titanium - magnetite series, and the formation of large-scale vanadium-titanium magnetite deposits. However, since vanadium is too dispersed in the ilmenite-magnetite series, it is impossible to obtain a vanadium independent phase by physical beneficiation, and only vanadium-bearing iron concentrate can be obtained. The vanadium content in the concentrate increases with the iron grade. improve. The vanadium-bearing iron concentrate is sintered and smelted, and the vanadium enters the molten iron. The vanadium slag is produced by an atomization blown vanadium process. Vanadium is then extracted by water immersion to effect separation of vanadium from iron.
