that the mica of siliceous shale containing vanadium transforms into the molten particle containing different elements. NaCl and Na2SO4 promote the generation of soluble potassium salt and the crystallization of albite from the molten particle. Na2CO3 inhibits the ion exchange between potassium and sodium, and the production of soluble potassium salt. At 750-800 ℃, reactions of sodium ions with potassium......
