Abstract:
     A process for producing humate includes such technological steps as crushing weathered coal or lignite into powder (0.25-1.0 mm), continuously loading it into drum granulator at 16-26 rpm, spraying the alkali solution (10-30 wt%) into said granulator, and granulating the humate in it and discharging from it. The ratio of coal to alkali solution is 1 :0.5 -1.5 by wt. Its advantages include simple process, short production period, low energy consumption, low cost and no residual dregs.
