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.

Paste Thickening of Fine Coal Refuse: Coal Preparation

The coal industry is being subjected to increasing public scrutiny with regards to its effect on the environment and impact on public health and safety. Recently, disposal and storage of fine coal waste slurry has drawn considerable public attention. This article discusses the emerging paste thickening technology as a possible solution to the fine coal waste slurry disposal problem.
