Dense-medium beneficiation of fine minus 0.5 mm coal is not a new concept and has been used in South Africa previously. The dense-medium fine coal plant at Greenside Colliery operated for almost 18 years and, despite proving a difficult plant to operate, did succeed in producing a fine coal
If coal is to be accepted as a primary energy source, it must be cleaned to prevent pollution of the environment either by cleaning the combustion products of the coal or cleaning the coal prior of burning. Accordingly, physical as well as chemical coal cleaning beneficiation processes have been explored.
In this study canary shell and coal were being the main materials for briquetting that would be made because canary shell assessed has high calorific value and not much cultivated and suitable to combine with coal to increase the calorific value, thus the beneficiation of canary shell as a mixture of coal briquette is being the purpose of this ...
The mined coal contains a mixture of different size fractions, together with unwanted impurities such as rock and dirt. Coal preparation beneficiation is the stage in coal production when the mined coal is processed into a range of clean, graded, and uniform coal products that are suitable
coal seams means that mining gives rise to a diversity of marketable coal products. The geological setting of the reserves largely determines the characteristics of the coal product to be marketed, but application of appropriate mining methods together with increasing levels of beneficiation can be applied to ensure that the product delivered ...

Coal preparation, or beneficiation, is a series of operations that remove mineral matter i.e., ash from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.
