Abstract
Thickeners have traditionally been used to dewater tailings streams containing fine coal from washeries. When British Coal built a new Baum Jig washery at Deep Navigation Colliery in Wales, UK, instead of a thickener they installed high performance hydrocyclones and horizontal belt filters to do the same job. Advantages included lower capital cost, easier operation and maintenance and considerably reduced space requirement. The hydrocyclones dewater and thicken underlows from dewatering screens and centrates from centrifuges. The filtered hydrocyclone underflow forms a fine coal product. Hydrocyclone overflow is returned to the jig as make up water. The paper describes in detail the design and operation of the washery circuit, highlighting the benefits gained from the use of hydrocyclones.
