Elutriation
Elutriation is the technique of separating a mixture of solid particles from a fluid (often a gas or liquid) using a vertical column through which the fluid is circulated, forcing the particles to settle at varying rates. It is the technique of separating particles based on their size, shape, and density by utilizing a stream of gas or liquid ...
