heal.abstract	This article is an overview on the beneficiation of the Greek lignites, one of the most important mineral commodities for Greece, with recoverable reserves amounting to about 4,000 Mt. This figure does not take into account a huge peat deposit. Almost all of the lignite mined annually (60 Mt/year) is used for energy production. The applied beneficiation methods include heavy media separation and jigging. The experimental results shots, that gravimetric separation is feasible. Comparison of the theoretical washability curves for xylite and lignite indicates that the xylite is more amenable to gravity separation than lignite. Heavy media separation proved to be more efficient than jigging. The degree of beneficiation depends on the clean coal specifications. Given that the lignite deposits in Greece have more or less similar characteristics, this article provides some general guidelines showing theoretical limits for beneficiation of these coals.	en
