Tailings Paste Disposal – More than Water Recovery

Aug 08, 2020· The coal tailings slurry used in this study was from a coal preparation plant in Jincheng, Shanxi Province, China. Fig. 1 shows the weight and ash content distributions of different particle size fractions of the coal tailings. It is obvious from Fig. 1 that the weight and ash content of the coal of –45 μm size fraction were higher than that in other size fractions, indicating a high ...

Tailings material handling can be divided into two categories of slurry pumping and dry cake material conveying and stacking. Centrifugal pumps are often used for pumping fine ground tailings material to the TSF. When transporting over longer distances, multi-stage slurry pumping is commonly used. Pumping of paste requires special pump modules and

Geotechnical Properties of Mine Tailings

The produced tailings were transported into a hydrocyclone sepa-ration facility, and two kinds of tailings were generated, i.e., coarse tailings from the bottom and fine tailings from the overflow of the hydrocyclone separation facility. The concentrations of the pro-duced coarse iron and fine iron tailings from the Yuhezhai iron

Copper Tailings Separation

Tailings dams can be huge in size, as big as lakes, and reach 300 metres high. As the slurry of waste is piped into the dam, the solids settle to the bottom and the water is recycled to be used in the separation process again. Rather than reinforced concrete, tailings dams use earth or rock to create a barrage.
