How to Start Extraction and Processing Business of Lignite from Lignite
Lignite is a type of coal that is formed from the remains of ancient plants and is highly combustible. It is the lowest grade of coal and is typically left in the ground unless it is in an area that requires extraction. In recent years, the extraction and processing of lignite has become more popular due to its ability to generate more energy than other sources such as oil …
