| titleOfInvention | The selecting smelting combination technique of vanadium, aluminium, potassium, silicon in a kind of synthetical recovery siliceous shale containing vanadium |
| abstract | The present invention is one kind using low-grade siliceous shale containing vanadium as raw material, the ore dressing field of metallurgy of synthetical recovery wherein vanadium, aluminium, potassium, silicon valuable component.Its step is using low-grade siliceous shale containing vanadium as raw material, vanadium siliceous shale method for floating desiliconization will first be contained, vanadium concentrate and excessive lime stone, sodium carbonate are roasted in rotary kiln high temperature after evenly mixing, obtain the products such as potassium aluminate, potassium ferrite, metavanadic acid calcium, calcium orthosilicate, carbon dioxide, sintered product is dissolved out in dilute alkaline soln, for dissolution fluid after desiliconization purifies, the carbon dioxide gas that rotary kiln generation is passed through in closed container carries out carburizing reagent, is precipitated Al (OH) 3 Precipitating, hydrolytic precipitation obtains thick vanadium to dealuminzation solution in acid condition, by thick vanadium alkali soluble solution, ammonium chloride is added and obtains ammonium metavanadate, last solution is rich potassium, rich sodium solution, obtains potash, soda through substep evaporation.The present invention thoroughly solves the problem of environmental pollution that the stockpiling of bone coal leached mud generates. |
