为从炼钢厂LD(Linz-Donawitz)转炉渣中提取钒,M.Aarabi-Karasgani等研究了一种碱性焙烧-酸法浸出工艺,并确定了各影响因素对钒溶解动力学的影响,浸出渣用XRD、XRF及SEM/EDX分析仪分析。最佳工艺条件:浸出温度70℃,固液质量体积1/15,酸浓度3 mol/L,浸出时间150 min,在此条件下,
In order to extract vanadium from converter slag of LD (Linz-Donawitz), M.Arabi-Karasgani et al. Studied an alkaline roasting-acid leaching process and determined the influence of various influencing factors on vanadium dissolution kinetics. Leaching residue was analyzed by XRD, XRF and SEM / EDX analyzer. The optimum conditions were as follows: leaching temperature 70 ℃, solid-liquid mass volume 1/15, acid concentration 3 mol / L and leaching time 150 min. Under these conditions,
