Abstract:An improved method based on Neumann way which is used to measure the contact angle has been developed to study more accurately the effect of mineral electropotential on its contact angle. The results of galena and pyrite showed that the wettability of mineral surface can be changed by adjusting the mineral electropotential. At certain electropotential, the contact angle of mineral surface can reach its maximum value.
Key words: Neumann way contact angle mineral electropotential electrochemistry of flotation
