摘要：A variant of application of Reinhardt's theorem for determination of separation densities at which it is possible to obtain the maximum ultimate yield of gravity concentrate with a particle size of 0.5- 100 mm at a given ash content obtained from hard-cleaning coals of two machine classes 13-100 and 0.5-13 mm is considered. The separation densities are found using the washability curves built in Microsoft Excel. The results of the theoretical and practical balances calculated for the found separation densities are compared. It has been established that for hard-cleaning coals in the practical balance, it is not always possible to obtain the ash content of the ultimate concentrate specified in the theoretical balance even with a decrease in the separation densities to a minimum value.
