Gravity concentration, past, present and future ...

1991-1-1  The future of gravity concentration depends on two main factors, first the application of energy from new sources to make possible the recovery of very fine particles, and second the ability to show that of all the processes available it is the most friendly to the "environment". If one considers the second factor first it is clear that the ...

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 ...
