Two types of mine tailings were treated: (i) freshly produced tailings coming directly from the flotation process, and (ii) tailings deposited in a tailings pond, for approximately 20 years.
The purpose of this note is to predict the dewatering behaviour of treated oil sand tailings over a short-term.
With its potential to produce stackable solids for backfill (land reclamation) and the highest quality and quantity of water (filtrate) for recycle, filtration for treating mature fine tailings (MFT) using an in-house synthesized, organic inorganic hybrid polymer (flocculant), Al-PAM, as a filtration aid was developed and tested on a MFT from oil sands operations.
Once the ore is removed, it is treated at a concentrating mill, which removes the waste rock (tailings) from the Pb by crushing the ore into granular pieces.
In these experiments, field-moist material was treated with an extracting solution to assess the effects of acidification on element mobility in mine tailings.
Anaerobically digested biosolids are preferred to aerobically treated biosolids because of higher nitrogen content and a greater enhancement of plant growth as tested in a copper mine tailings site (McNearny 1998).
In an effort to address public concerns of the long-term stability and ecological risk reduction of phosphate (P -stabilized lead (P -stabilizedastes, mileadailings located at the JasPbr County Superfund Sine of southwest mineouri, containing ~ 4000 mg Pb kg− 1, wastesreated in situ by phosphoric acid at three rates: 0; 7.5; and 10.0 g P kg− 1 soil.
The study evaluated the ability of wetlands built on tailings impoundments to prevent AMD formation and to treat already formed AMD, with special emphasis on the role of wetland plants in the remediation process.
The proliferation of unsightly and potentially hazardous coal discard dumps and tailings dams in particular, requires that the mining industry find new ways of treating waste.
Consequently, oil sands mines are surrounded by vast tailings ponds….
