摘要
利用风化煤中腐植酸成分与杂质成分颗粒密度的差异，以及它们在水中自由沉降速度的不同，应用水力沉降法富集腐植酸，达到分离杂质，富集腐植酸的目的。试验用的风化煤腐植酸含量为５８．４２％，经水力沉降法富集后，可使产品腐植酸总量提高到６４％以上。
The impurity is seperated and the humic acid is purified by taking advantage of the difference between the density of the humic acid and that of the impurity and their free-subsiding velocities in the effloresced coal. The content of humic acid in the original effloresced coal is 58.42%, and after hydro-subsiding, the total content of humic acid is more than 64%.
