The objective of the present study is to utilize, and if necessary further develop, mathematical model to predict the conditions for optimum selectivity in coal-coal pyrite/coal refuse system with a given flocculant. Coal and coal refuse from Pittsburgh-Bruceton mine and coal pyrite from a southwestern Pennsylvania coal preparation plant were used in this study. Several polymers, including polyacrylamides, polyethylene oxide and hydrophobic polymers were examined for their selectivity towards flocculating coal, coal refuse or coal pyrite. The computational model for the coal-coal pyrite/coal refuse system was developed and rewriting the computer program in FORTRAN (it was originally written in PASCAL) was completed. This with the aid of advance programming techniques, enabled computation with more particles than was possible before. 31 refs., 30 figs., 11 tabs.
