Gravity separation has the advantages of simple equipment structure and low operating cost, so it can be used whenever conditions are suitable.

Main applications of gravity separation include: (1) separation of precious metals such as gold and platinum; (2) separation of tungsten and tin ores; (3) widespread application in the treatment of placer deposits containing rare metal elements, such as the separation of coastal placer deposits containing zirconium and titanium minerals; (4) separation of hematite and limonite; (5) separation of manganese ore; (6) separation of clean coal and gangue in coal preparation plants; (7) separation of some non-metallic minerals from gangue, such as the separation of asbestos, mica, kaolin, sepiolite, and diamond; (8) pre-enrichment of non-ferrous metal ores such as copper, lead, and zinc, which are mainly treated by flotation, using gravity separation; (9) the process of separating by particle size in gravity separation, such as grading and desliming. Gravity separation is an indispensable operation in almost all ore processing plants.
