Application of Water Based Fractionation in the Assessment of Metallurgical Coal. The metallurgical coal market (13% of coal market) is highly specialized, and competitive. The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities.

The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities. A new water based fractionation method will be established, and a systematic investigation into the effects of the organic liquids will be undertaken. These results will be used to build a case for replacing the organic liquids used in the industry, which are known to have negative health and environmental impacts. Read moreRead less
Dry Processing of Fine Coal Using the Reflux Classifier. New and efficient separation technologies are crucial for developing the concept of Dry Coal Processing. The benefits to the industry of Dry Processing are compelling, with savings in water consumption, and much larger savings in dewatering and transportation of the product. The Reflux Classifier is a new fluidized bed technology developed in Australia using the more conventional water fluidization approach. Already the technology is contr ....Dry Processing of Fine Coal Using the Reflux Classifier. New and efficient separation technologies are crucial for developing the concept of Dry Coal Processing. The benefits to the industry of Dry Processing are compelling, with savings in water consumption, and much larger savings in dewatering and transportation of the product. The Reflux Classifier is a new fluidized bed technology developed in Australia using the more conventional water fluidization approach. Already the technology is contributing to Australian exports in the rapidly growing area of mining services. The purpose of this project is to establish its potential for use in the Dry Processing of fine coal. Other benefits of the study include the education and training of researchers in this field.Read moreRead less
