摘要: In order to investigate the difference in flotation kinetics of various size fractions bituminous coal between rougher and cleaner processes, clean was collected as a function time both processes. The composition then analyzed. Six kinetic models were applied modeling data from tests by using MATrix LABoratory software. relationship rate constant, maximum combustible recovery particle also studied. results show that are obtained with an intermediate higher process than process. Except classical first-order model, other five gave excellent fit data. can be described second-order while only model. It is found model rectangular distribution floatability provides best experimental processes among tested models.
