Research on the Occurrence State of Vanadium of Pingbian Vanadium Ore in Honghe County

By chemical analysis,grinding optical sheet(observing by microscope),artificial placer analysis and scanning electron microscope electron microprobe analysis,it is found that the Pingbian vanadium ore belongs to the sedimentary type vanadium ore,the main types of which are silty mudstone,fine calcarenite,micritic limestone and siliceous slate.The vanadium has two kinds of occurrence state.The first one is in the form of isomorphism(partly because of the carbon of mineral inclusions adsorbing vanadium),accou...
