Shrinking core model leaching
SpletIn the first 15 min, a sharp increase in the amount of vanadium extracted was observed and at longer times, leaching became slower. Shrinking core model (SCM) was used to describe the kinetics of the slag acid leaching. … SpletQuantitatively, the percentage of errors from the shrinking core model is around 3.5 times greater than the percentage of errors from using the lumped model. This result shows …
