Embodiment 1
[0022] According to the above-mentioned crushing ball mill sieving, batching, acid leaching, oxidation, ion exchange adsorption, ion exchange desorption, vanadium precipitation, calcination, ion exchange tail water purification and impurity removal, evaporation and concentration, etc., the steps are sequentially operated. Stone coal with a vanadium-containing grade of 1.0% is used as raw material, and the ratio of the amount of vanadium contained in the stone coal vanadium ore to the amount of manganese dioxide contained in the pyrolusite is 1:1. The leaching rate of vanadium in coal is 95%, the recovery rate of vanadium is 86%, the leaching rate of manganese in pyrolusite is 98%, and the total recovery rate of manganese is 91%.
Embodiment 2
[0024] According to the above-mentioned crushing ball mill sieving, batching, acid leaching, oxidation, ion exchange adsorption, ion exchange desorption, vanadium precipitation, calcination, ion exchange tail water purification and impurity removal, evaporation and concentration, etc., the steps are sequentially operated. Stone coal with a vanadium-containing grade of 1.5% is used as raw material, and the ratio of the amount of vanadium contained in the stone coal vanadium ore to the amount of manganese dioxide contained in the pyrolusite is 1:1. The leaching rate of vanadium in coal is 96%, the recovery rate of vanadium is 87%, the leaching rate of manganese in pyrolusite is 97%, and the total recovery rate of manganese is 90%.
Embodiment 3
[0026] According to the above-mentioned crushing ball mill sieving, batching, acid leaching, oxidation, ion exchange adsorption, ion exchange desorption, vanadium precipitation, calcination, ion exchange tail water purification and impurity removal, evaporation and concentration, etc., the steps are sequentially operated. Stone coal with a vanadium-containing grade of 1.0% is used as raw material, and the ratio of the amount of vanadium contained in the stone coal vanadium ore to the amount of manganese dioxide contained in the pyrolusite is 1:2. The leaching rate of vanadium in coal is 98%, the recovery rate of vanadium is 89%, the leaching rate of manganese in pyrolusite is 96%, and the total recovery rate of manganese is 88%.
