ABSTRACT

In this work, samples were taken from Koyunagili Lignites Company Washing Plant
feed and were subjected to extensive research to determine the floatability of lignite
fines. The optimum conditions of flotation were determined under the laboratory
conditions by using a laboratory type Denver flotation cell. In the flotation experiments
particle size distribution, collector type and amount and dispersant amount were tested
as variables. After flotation experiments, at optimum conditions, 53.91 % of the sample
was floated with 29.54 % ash content.

Keywords: lignite fines, floatability
