The Microwave Infection on the Extraction of Vanadium from Stone Coal

SI Shi-hui,QI Bin-bin (School of chemistry and chemical Engineening Central South Univerdty,Changshu 410083,China)  
In the extraction of vanadium from stone coal microwave could change the appearance and surface of stone coal.After 25 minutes' irradiation in microwave,the SBET increased 30%.The heating by microwave was fast,and it also had un-caloric effect.After 30 minutes' irradiation the conductance of H_2SO_4 sparse solution increased 20%.The extraction rate of vanadium had reached to 67%in microwave;on the other hand it can only reach to 55%in the traditional way.The effect of extraction had improved obviously,andhe time also reduced to 1/ 6 of the quondam time.It saved much time andecreased the energy and pollution of technique process.
