Data based on samples taken at the ten operating washeries during the period indicated that the average
It allows the user to simulate coal preparation plants to determine an optimum plant configuration for a given degree of cleaning. The user can compare the performance of alternative plant configurations as well as determine the impact of various modes of operation for a proposed configuration.
Coal preparation can be a costly portion of the raw material production chain, given the large throughput requirements and the variety of technologies needed to create a suitable product. As a result, coal preparation requires carefully engineered processing plants which employ low-cost solid–solid and solid–liquid separation processes.

A new coal preparation plant simulator has been developed to select the most profitable cleaning circuit-configuration based on a comprehensive techno-economic analysis of the feed coal ...
The design differs from the typical "one size fits all" approach to coal prep. Plant design must be based on the characteristics of coal being washed and the market that plant serves. The further the raw coal quality is from the clean coal quality, the more complicated the plant becomes.
This phenomenon has driven thermal coal treatment circuit design in Australia, the USA, and South Africa, which commonly all discard nominal − 0.15 mm material.A typical Australian steam coal preparation plant is shown as Fig. 14.1 (Firth et al., 2006).An American thermal coal plant would be similar except that instead of two …
