Concentration of Ores – Study Material for IIT JEE ...

Thickening: Prior to precipitation, it is sometimes advantageous to concentrate the solution. This is especially true to learn materials, the leached solution of which are usually diluted or contain large amount of impurities. This concentration is called thickening. It is accomplished by means of ion-exchange method.

GRAVITY THICKENING OF ACTIVATED SLUDGE

to be able to concentrate sludge prior to subsequent dewatering processes. One process that concentrates or thickens sludge is known as gravity thickening. Gravity thickening of sludge is defined as a process by which particles, or aggregates of particles of dilute sludge, due to their greater specific gravity, settle through water and concentrate.
