In this paper a humate surfactant based on humic substances which were derived from lignite by modification of hydroxymethylation and esterification methods respectively was prepared Determined by surface tension method the cmc critical micelle concentration of the humate surfactant is g/L and the corresponding surface tension is mN/m The
Although coal is a major source of power for developing countries because of its low cost and abundant reserves coal combustion is the primary cause of CO 2 emissions which is the major contributor to climate change Xiao et al 2022 As a low rank coal lignite with high moisture and ash content can produce considerable carbon emissions
Lignite Lignite is a dark brown/black mineral formed by the partial decaying of organic matter in the presence of high pressure and temperature Lignite is the poorest form of coal containing 60 70% carbon and 6 9% mineral content For its use as a carrier material lignite is grinded to a particle size of less than 40 μm

Altogether the second fluid and the second particle have good performances in decreasing the viscosity of suspension of some hydrophilic or hydrophobic particles but there are still no systematic reports on the preparation of CWS of lignite using the second fluid and the second particle and this needs to be investigated carefully
In the current study extraction of humic acid HAs from lignite fines of kutch basin of Gujarat western India were reported The preparation of pellet was done by mixing thoroughly 2 mg of
Meanwhile we review progress in lignite flotation in recent years In addition we analysed lignite flotation methods including grinding reverse flotation heating microwaving ultrasonic oily bubbles flotation and modification of collectors The advantages and difficulties of the methods above are discussed from a molecular level
In this work lignite was used as the raw material and the KOH activation method was adopted to prepare AC for removing SO 2 from simulated flue gas This method contributes to improving the economic value of lignite broadening the application fields of lignite and reducing the desulfurization cost of flue gas
