Tailings Centrifuge

The centrifuge technology process consists of three steps. The FFT is dredged from the tailings pond. A polymer (the same kind that is used at a municipal water treatment plant) is added to the FFT slurry. The slurry is then fed into a centrifuge that spins the water out and produces a clay material that has the consistency of a mud cake.

Tailings pond

Tailings ponds are one of the methods used to store tailings, the waste material left over from ore extraction processes. Tailings are often mixed with water to create a slurry, which is easier to transport. One method of storing the slurry is in tailings ponds (Figure 1). Depending on the design of the pond, this may or may not also include the use of a tailings .

Tailings Management

Oct 19, 2021· They are typically created as mined ore is crushed, ground and/or processed to separate the valuable minerals and create a saleable concentrate product. The waste from this process is called tailings. Due to the nature of the ore separation processes, tailings are commonly in the form of a slurry of fine mineral particles and water.

A Protocol for Reclaiming In-Pit Tailings Ponds to Exceed

tailings are flowing, the longer the solids within the slurry will take to settle out. While particle size distribution affects the surface slope of the deposited solids and the rate at which the solids settle out of the slurry, the slope can also be determined from a nearby tailings pond that uses the same tailings slurry.
