DOI: 10.1007/s10230-020-00707-5
Abstract: The Lausitzer und Mitteldeutsche Bergbau Verwaltungsgesellschaft (LMBV), a state-owned company, is the responsible partner for remediation of East Germany’s lignite mining areas. This includes the obligation to create ecological and economically sustainable pit lakes. LMBV… read more here.

DOI: 10.1016/j.fuel.2018.02.034
Abstract: Abstract Hydrothermal treatment (HT) is traditionally used as an approach for upgrading lignite. But this approach has a limited effectiveness for upgrading high-ash lignite. In this study, we explore a new method for substantial upgrading… read more here.

DOI: 10.1021/acs.energyfuels.7b03069
Abstract: The low rank coal lignite stands out to be a profuse source of energy in Turkey and accounts for nearly 43% of its total fossil fuel production. However, the high sulfur content associated with lignite… read more here.

DOI: 10.17159/2411-9717/568/2019
Abstract: The majority of lignite deposits in Greece consist of multiple thin lignite layers and are traditionally estimated using a one-dimensional compositing approach that can potentially lead to large errors, particularly in the presence of medium… read more here.

DOI: 10.7306/gq.1545
Abstract: Non-tectonic, soft-sediment deformation structures occur in mid-Miocene crevasse-splay deposits exposed in the Tomislawice lignite opencast mine in central Poland. The crevasse-splay cross-stratified siliciclastic deposits are underlain by continuously folded and relatively thick lignite beds, and… read more here.
