Effects of pulp chemistry on plant and laboratory flotation modellingBy A L. Randriamanjatosoa, G Small, C Greet
In flotation simulation models, the effects of pulp chemistry other than pH are often ignored and reduced to particles hydrophobicity or contact angle, neither of which can be measured readily in real
