The coal is then transported from site to the Port of Newcastle via rail for export. In 2010, the Preparation Plant successfully installed a paste thickener, the first of its kind in coal processing. The aim of the paste thickener is to thicken tailings which saves on water, power and reduces space required for tailing storage.

automated control of the plant. All mining concentrators and coal preparation plants have tailings thickeners. These instruments treat the process water by removing suspended solids and then returning the water back to the concentrator or coal prep plant. They then pump the solids to a tailings dam.


Figure 2: Paste backfill plant with deep cone thickener, Lisheen Mine, Ireland (© Jon Engels) Advantages: The tailings are stored underground and thus prevent surface disturbance. This is more environmentally friendly as areas of land don't have to be used for a surface tailings storage area. Problems associated with dust generation, visual ...

Theory and Application of Thickener Design

A customer had multiple coal types, that were processed through the preparation plant. Some of the coal types had different settling characteristics, which affected tailings thickener efficiency and the "clarometer" instrument that tested settling rates in the incoming feed well failed from time to time, which meant that the floccing rate changed and the suspended solids increased ...
