WASHERY ANALYSIS - Free download as Word Doc (.doc), PDF File (.pdf), Text File (.txt) or read online for free. The document analyzes the properties of washery rejects from a coal washing process. It shows that the rejects have 9.98% moisture, 62.3% ash, 20.62% carbon, and a gross calorific value of 1700 kcal/kg. Testing of the raw coal feed and …
Coal washery is an establishment where coal is alienated from slate and different impurities through various mechanical processes which utilize water and take gain of the difference in the specific gravity and its impurities of coal. The more impurities or waste material is removed from the coal the greater is the market value and lower ash ...

Coal washing Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties. In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture. Thus, before coal can be sold to consumers, it must be cleaned. The cleaning process consists of a number of steps that results in a product …
Flotation tailings are by-products of coal preparation plants, which do not only occupy cultivated land but also cause pollution. The high ash content and low calorific value of tailings limit their applications. Deashing is the precondition for the reutilization of flotation tailings. However, it is more difficult to remove ash content from flotation tailings …

It is worth noting that the sizes of washery wastes rely on the specific coal production operation technology and presumably vary in each coal-producing country. Nevertheless, the corresponding values should not vary significantly due to a similar procedure in different countries with similar mechanization levels.
