Enhanced lignite flotation using interfacial nanobubbles based on temperature difference method
Fuel, 2021Froth flotation is the primary method for the separation and upgrading of fine coal particles. However, this method is ineffective for lignite which is more hydrophilic than other types of coal due to the abundant oxygenated functional groups, cracks ...

The biotic effects of lignite on humic acid components conversion during chicken manure composting.
Bioresource TechnologyTargeted regulation of composting to convert organic matter into humic acid (HA) holds significant importance in compost quality. Owing to its low carbon content, chicken manure compost often requires carbon supplements to promote the humification ...

The first demonstration that samples of lignite at a depth of 10 m are considerably enriched in bacteria is reported. According to direct microscopy, the abundance of bacteria was about 107 cells/g. About 70% of cells had intact cell membranes and small size, which points to their anabiotic state.

Preparation and evaluation of lignite flotation collector derived from waste hot-pot oil
, 2020Due to poor hydrophobicity, large amounts of petroleum-based collectors are required for upgrading lignite. In this paper, Waste Hot-pot Oil (WHPO) collectors from the catering industry were prepared via filtration, heating, and catalysis.
