Mar 26, 2020· In worst case examples, the tailings can exhibit the properties of a liquid. It can take many years (>10) for the top surface of soft tailings to dry and consolidate to a state that will support direct access by earthmoving equipment to facilitate safe placement of fill materials for closure and rehabilitation purposes.
Tailings Wikipedia
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

Is rhizosphere remediation sufficient for sustainable
An initial rapid oxidation of sulfides has been reported when fresh tailings were deposited in tailings storage facilities, resulting in a pH decline from 9–10 to 8·7–9·8 (Dold and Fontbote, 2002; Smuda et al., 2008). However, the oxidation rate may quickly slow due to the lack of oxygen in the pore space caused by sedimentation and
