Contact Angle Measurement of Magnesite Mineral in Alkaline pH by Using the Simple Bubble Attachment Method

Abstract

Contact angle is one of the most important parameters for the flotation process. Researchers have performed many experiments and used many different methods to determine the contact angle. In this present study, simple bubble attachment method (SBA), which was firstly utilized by Hunning and Rutter (1989), was used to determine the contact angle of magnesite mineral in the presence of various amount of collector such as oleic acid,  R801, R845, sodium dodecyl sulphate and sodium oleat. According to the results of SBA, the highest degree of contact angle was obtained as 82ᵒ at the presence of oleic acid. The results of the study show that SBA method seems like a cheap and beneficial method for contact angle measurement.
