Preliminary Study of a Method for Obtaining Brown Coal

 · Brown coal sample was characterized by the relatively high free humic acid values (> 50 ). Research showed that humic acids occur naturally in lignite and can account from 10 to 80 depending on the maturity level of the lignite organic matter 31 32 . For example the content of humic acids in Greek leonardites was below 20 and seldom below 30 .
