Determination of Vanadium Valency in Roasted Stone Coal …

2011-9-1 · Stone coal is an important vanadium-bearing resource in China. Most vanadium exists in stone coal as V(III), which is stable and not easily to be extracted. The V(III) should be oxidized to V(IV) and/or V(V) by roasting with additives at high temperature and then extracted by acid leaching and/or water leaching. Hence, the vanadium valency in roasted stone coal can reflect …Stones in coal, lots of clinkers - Solid Fuels: Coal, Coke ... · Coal, Coke, and Rocks. by Glenn Conner. Coal, to many people, is a black rock that sometimes can be burned. To a blacksmith, it is the fuel used in the forge to heat the metal, and comes in two varieties, good and bad. "Good coal" produces high heat, little ash, little clinkers (slag) and makes life so much easier.
