Model for Prediction of the Concentration of Extracted Tin

Model for prediction of the concentration of tin extracted during potassium hydroxide leaching of cassiterite has been derived. The model A = Nt 1.53 , indicates that the concentration tin extracted is dependent on the residence time. It was found that the validity of the model is rooted in the expression Log A = Log (Nt 1.53 ).
