· The specific Gravity-bottle method
specific gravity bottle is a device used to determine the density of a liquid. This is called the pycnometer. A pycnometer is usually made of glass, with a close-fitting ground glass stopper with a capillary tube through it, so that air bubbles may escape from the apparatus. This device enables a liquid's density to be measured accurately by reference to an appropriate working fluid, such as water or mercury, using an analytical balance.
· The Sink-and-float method
Depending on the weight of solid particles, the raw material of the group divided into two or more research or a specific portion of the configuration elements for the purpose of separating particles do the test methods.
