Humic acids and humic acid mono chelates of microelements important in animal and plant nutrition are prepd. by an alkaline hydroxy extraction of carbonaceous materials of low degree of carbonisation as lignite or pest. Humic acids are obtd. from the extracts by addn. of acids. Microelement chelates are obtd. if prior to the acid pptn., pref. water soluble, salts of microelements were added to the alkaline extract.
