Tailings Management Tailings are a slurry like material which consist of finely ground rock, process water and residual reagents. This is the leftover material after the copper concentrate is extracted from ore. Some of the tailings are mixed with a cement binder and used to backfill mined areas underground as a geotechnical ground support method.
Before leaching, the water in the tailings is reduced by use of conventional thickeners to produce underflow slurry with less water and overflow water recycled for plant use. 2.1 Pre Leach Thickeners There are two pre leach thickeners, RPLT and CPLT.

Bins are boring, drab accessories. What a load of rubbish! With our waste bins, you can find something that not only provides that practical feature in your home but enhances the overall space, too. For example, our kitchen waste bins are available in a range of styles, including gorgeous contemporary pedal bins and traditional plastic swing bins. And this exemplary style isn't reserved solely
01/02/2020· The iron grade of the iron ore tailings was significantly improved by discarding 38.51 of the tailings, and a preconcentration concentrate containing 26.01 Fe at an iron recovery of 82.71 was obtained. The preconcentration concentrate was precipitated, dried, ground, blended, and used as the feedstock for the SMR process. The application of the pre concentration process greatly reduced
One of the most successful economic projects in using tailings as a resource is the Ergo Project, which involves large scale tailings hydraulicking and reprocessing of gold tailings in the Johannesburg area of South Africa. The project was established in the 1980s and has gone through multiple renewals. After removing the tailings and recovering gold and uranium, the land is made available for
Concentrator and high efficiency concentrator are suitable for concentrating concentrate or dewatering tailings before filtration. They can also be widely used for concentrating and purifying solid slurry in smelting, coal, chemical industry, building materials, water supply and sewage treatment industries.
