Effect of grinding on the crystal structure of recently excavated dolomite

Abstract

Transmission FTIR technique was used to identify the minerals in recently excavated dolomites and study the structural changes of dolomite upon grinding at various grinding periods. KBr pressed disk technique was found to be very useful for a routine characterization of minerals, for examination of structural modification of dolomite and formation of new minerals during grinding. These minerals and processes were also determined using XRD and SEM analysis. The minerals which were formed upon grinding dolomite, were aragonite, anorthite, metakaolinite and periclase.
