摘要:

Potential production methods for the production of low ash coal were investigated using a variety of Australian coal samples including natural fines, washed coal and washery rejects. Many samples could produce coal of less than 3% ash at yields exceeding 70% but the costs of comminution, beneficiation and dewatering for potential markets exceeded the value placed upon the low ash product.
