Flotace černého uhlí

Abstract

The work deals with the use of a new type of flotation reagents, emerging as a product of pyrolysis of waste materials and tires and wood, for flotation of coal. For comparison, the results of flotation reagents based pyrolysis oils labeled P550, KOPD9 and KOPD11 was commonly used agent Montanol 551. With flotation was also examined the effect of particle size composition. The target value of ash was set at less than 10 % and yields at least a minimum limit of 70 %. As the sample was used coal from the Lazy Mine.
