Experimental Study on Spontaneous Combustion Characteristics . · When the temperature of coal was 50–110 °C, soaking in water for 7 days could promote the oxidation and spontaneous combustion of coal. However, soaking for 14 and 21 days had a significant inhibition effect in this temperature range. When the coal temperature was higher than 110 °C, water immersion had a significant inhibition effect on the coal.
LeonarditeLeonardite is a soft waxy, black or brown, shiny, vitreous mineraloid that is easily soluble in alkaline solutions. It is an oxidation product of lignite, associated with nearsurface mining. It is a rich source of humic acid (up to 90%) and is used as a soil conditioner, as a stabilizer for ionexchange resins in water treatment, in the remediation of polluted environments and as a .

(PDF) Identifiion of Leonardite, a Naturally Oxidized Lignite. · Leonardite is naturally oxidized lignite characterized by high content of humic and fulvic acids which are used in the agricultural production (Broughton, 1972, Lee and Barlett, 1976).
USAThe invention relates to a process for crushing raw lignite. The raw lignite is dried with an exit temperature after drying of approximately 70° to 85° C. The dried raw lignite is then crushed. This crushing of the dried raw lignite is performed in an airswept roller mill, in which the crushing and cooling of the lignite particles is brought about by the inflowing cold and/or ambient air to ...
