Paste thickening optimizes tailings disposal and water …
To maximize water reuse, the Khumani plant contracted with WesTech Engineering, Inc. to design and implement a two-stage tailings thickening process. The first stage consists of two primary high-rate traction slurry thickeners, each 295 feet in diameter, situated at the main plant. The first was installed in 2008, with the opening of the mine.

Solutions for Surface Disposal of Mine Tailings
Cemented paste tailings (CPT) is a pumpable, flowable, non-Newtonian fluid generally prepared by mixing mine tailings, water, and binder. CPT is generally a nonsegregating mixture with a solid concentration of 70–85% and contains enough fines (at least 15% particles less than 20 microns) to prevent settlement and particle segregation …

Tailing Disposal
2.4 Beaching behavior of mine tailings. The predominant method of tailings disposal is by pumping and sub-aerial deposition of an aqueous slurry (typically at 30–45% initial solids concentration by mass and an initial gravimetric moisture content, w, of 233–122%) to a surface TSF. The tailings may be discharged from a single pipe outlet or ...

Acid Rock Drainage Mitigation
Ok Tedi Mine is the only large copper mine in the world to separate sulphides from the tailings before tailings discharge. The risk of acid rock drainage identified before 2008 due to high sulphur levels and insufficient neutralising capacity in the sediments is now managed with the implementation of the Mine Waste Tailings Project (MWTP).
