Nové flotační sběrače ve flotaci černého uhlí

Abstract

In this thesis, the coal from Lazy and Staříč Mine in OKR was used for the flotation tests during the research. This thesis deals with the research of new flotation collectors from wooden pyrolysis waste and compares them with commercially available agent Belgian montanol 508 which is used in black coal flotation. Another aspect of the test is mixing montanol 508 and pyrolysis waste in order to get better flotation. The aim was to obtain a suitable coal concentrate used for sale, in which the ash content is lower than 10%. Another aim of this thesis was either replacement of the agent used till now or reduction of the agent consumption in the flotation process, using the appropriate combination with wooden pyrolysis waste.
