Paste thickening (1 reply and 1 comment)

Hello collegues!

Nowadays, paste thickening is very common, for instance, in China and other countries, but still not in Russia.

Please advice, what are the main conditions of use, what are the key tailings characteristics that determine its use.

If you could advice any literature about paste, I will be highly appreciated.


Thank you,

Until a Pro comes along, review

The use of a thickener, without filtration, to produce a non-settling paste (also called thickened tailings) with non-Newtonian rheology has been practiced in Australia for many years for red mud disposal. The application of paste thickening technology outside of alumina is relatively new. Interest and installations in paste thickening are rapidly growing. Water shortages and environmental pressures make consideration of thickening tailings to solids concentrations within the paste range necessary in most new tailings projects. The paste thickeners at the DeBeers CTP plant in Kimberley, South Africa are an example of paste tailings disposal on the surface, also called “stacking” (Houman, 2003). This paper describes the principles of design and general operating characteristics of the paste thickener. The application and operating performance of paste thickeners in surface disposal is discussed using iron ore tailings, as produced in a one meter paste thickener pilot plant, as an example.
