A processing route involving low temperature carbonization followed by dry magnetic separation is put forward for the desulfurization and deashing of typical low-rank lignitic coals. The 23 mm lignite samples were subjected to low temperature carbonization at 6008C for 15 min and then upgraded by ma

The degree of conversion of the coals studied to the products solubility in dichloromethane was found to be surprisingly high regarding the low-rank coals. This paper puts forward an hypothes
