Imperfections in Solids | MATSE 81: Materials In Today's World

Imperfections in Solids. Print. There is no such thing as a perfect crystal. Crystalline imperfections (or defects) are always present. In addition, impurity atoms are always present. Many of the properties of materials are sensitive to the presence of imperfections, and not necessarily in an adverse way. So, what kind of imperfections exist in ...

This is used to separate mixtures of solid-solid particles and liquid ...

Mineral processing - Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
