- W4249846822 abstract "A series of fine coal kinetic tests were carried out on three coals. It was found that the rank of flotation rates for the three coals tested were: Upper Freeport > Pittsburgh No. 8 > Illinois No. 6. In the case of Pittsburgh No. 8, the contained coal-pyrite was found to float more slowly than the coal itself when xanthate was used as the collector. In kinetic modeling, first order kinetic models produced large errors for long flotation times. It was found that a modified first order kinetic-model with slow and fast rate constants was appropriate for fine coal flotation. A log-log plot of 1(R{sub j} -R) versus t forms a straight line for the test conditions of this study. The Lai proportionality flotation model was found to apply from the start and extending over a very broad time range." @default.
