Sieving includes using a set of sieves arranged from largest to smallest mesh size to individual powder fractions. Cyclone and air separators use centrifugal forces to separate solids from gases. Elutriation separates powders based on particle density variances in a very moving fluid.
The document discusses suspensions, which are heterogeneous techniques with modest, sound particles dispersed in the course of a liquid medium. Suspensions can be used orally, parenterally, or externally. They are divided into coarse and colloidal suspensions depending on particle size.
