Abstract:

The paer introduce the original slurry treatment system of the Antai coal preparation plant and existing problems, By analysis the size composition of the flotation feed , Proved the process optimization is necessary and reasonable. And proposing the optimization program to adjust the flotation feed composition and the flow direction of the filtrate. By comparing the results of the original process and optimized process and analyzing its economic benefits, Evaluation of its optimization results, The results showed the technology Optimization not only solved the problem that the flotation is poor and the concentrations of circulating water is high, but also Got better economic efficiency and environmental benefits

Key words: slurry, flotation, filtrate, the concentrations of circulating water
