2018. 3. 23. Mining for lignite or brown coal in Greece is a huge industry. But for residents of villages in the extraction areas of West Macedonia, it has many impacts, from displacement to health problems
2021. 1. 25. Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat.It is considered the lowest rank of coal due to its relatively low heat content.It has a carbon content around 25 to 35
Of the 80,000 jobs in brown coal mining when it was still part of the former East Germany, only 8,000 Brown coal, or lignite, is used to produce around a quarter of German electricity output.
2 天前 Germany has been the largest lignite producer in the world since the beginning of industrial lignite mining. It still is, followed by China, Russia, and the United States. The softer and moister lignite (also called brown or soft coal) has a lower calorific value than hard coal and can only be mined in opencast operations. When burned, it is more CO2 intensive than hard coal.
Lignite, or brown coal, is the lowest-ranked coal, and is placed just above peat in terms of calorific value. It is not a feature of international seaborne coal trades, primarily due to its high water content (which can reach up to 60 per cent) and its lower Btu values (which average 4000–8300 Btu/lb compared with bituminous coals, which average 8500–14 000 Btu/lb).
