Improved dewatering of iron ore fines by the use of

Jan 01, 2016 The bed of the iron ore fines formed on the dewatering screen can be thought of as a cake of fine and ultrafine mineral particles on a filter cloth. The dewatering phenomenon is often quantified by the Laplace–Young equation, which relates the pressure necessary to drain a capillary to the surface tension, contact angle and a nominal

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water
