The hand selection method is a sorting method based on the difference in color and appearance between lithium minerals and gangue minerals. The selective particle size is generally 10 to 25 mm, and the determination of the lower limit of the particle size depends on economic benefits. Hand selection is the earliest method of mineral …

Spiral classifiers can grade different particles in ore slurry during the metal beneficiation process as well as deslime and dehydrate in the washing operation. They are widely used to separate ore sands by forming a closed-circuit with the ball mill in concentrators, or in gravity concentrators to classify ores and fine muds.

A Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. It has an inclined trough with one or two spirals revolving slowly and free from touching the sides or bottom of the tank. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore.
