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 f...

Tectonic hollow of Kosovo with characteristic geological construction, specific geological - historical development and the presence of a great number of lignite strata in new sediments, present a very interesting region, specific for multidimensional study. The considerable reserves of lignite in Kosovo basin, ascertain from geological exploration, present important recourse in one side whereas its exploitation for combustion in Kosovo power plants presents a great environmental problem on the other side.
