The paper presents a study on the phenomenon of wetting of minerals in the two cases where a wetted solid is placed on a liquid surface and a liquid is on a flat solid surface. Knowledge of physical and chemical processes occurring between a liquid and solid is an important issue. Contact angle measurement and determination of interfacial tensions are very important in development of new technologies in which the gas-liquid-solid system appears. These problems are important for new solutions in many industries. The study confirms that many factors have an essential influence on the contact angle measurement.
