To carry out washery optimization calculations in a digital computer, both the raw coal feed characteristics and separator efficiency performance must be reduced to a form that is both accurate and easy to translate into code. A systematic analysis has been made of mathematical representation for partition curves and separation characteristics for froth flotation machines. A number of representations of the partition curves have been found to be useful. The programs developed accept conventional partition data or modelled partition curve parameters. Flotation performance is specified according to a two-rate constant kinetic model. Feed coal characteristics used are typical for coal preparation plants in China. All the programs have been proved to be effective and convenient tools for the design and operation of coal preparation plants. 15 references.
