Gravity separation process is used for the concentration of

Gravity separation process is used for the concentration of haematite. Gravity method is based on the difference between the densities of the ore particle and gangue. It is used for the concentration of denser ores from the water soluble and lighter impurities (gangue). Oxide ores and carbonate ores are concentrated by this method.

Gravity Separation - an overview ScienceDirect Topics

Gravity separation is sufficient for production of good-quality steam at lower boiler operating pressures (e.g., 150 lb/in. 2), where the steam and water density differential is great and the steam drum is adequate for the steam load.. Antifoam agents can significantly reduce carryover caused by chemical factors. Compounds classified as polyalcohols and polyamides are particularly effective in ...
