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 153 , 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 153 )
