Abstract

Surface chemical properties of minerals are known to be strongly influenced by the surface heterogeneities which arise from either natural variations in the chemical composition and crystal structure of the mineral or pretreatments given during sample preparation. Large discrepancies are often found in the values reported for the surface properties of the same mineral. These variations mostly occur due to different sample preparation techniques employed by investigators and sometimes, due to impurities present in the liquid or gas phase with which the mineral particles are contacted. To elucidate the mechanisms underlying the various interfacial processes it is essential to avoid the artifacts introduced by sample preparation techniques. An understanding of the effects of pretreatments on the surface properties of the minerals can be helpful in this regard in obtaining consistent and reproducible results. In this paper commonly used pretreatments for obtaining clean mineral surfaces and their implications in the study of interfacial phenomena are discussed.
