n: organic acids of indefinite composition in naturally occurring leonardite lignite. The humic acids are the most valuable constituent. See lignins.

n: a kind of crude organic macromolecule compound.

n: The mineral leonardite, similar to brown coal. Lignite is found in surface deposits worldwide. Lignite is mined and put into piles where it can oxidize in the air before it is dried, ground and bagged for use in drilling fluids. The humic acid content of

very young coal. Moderate to low energy yield.

n pi: naturally occurring special lignite. e.g., leonardite. that is produced by strip mining from special lignite deposits. The active ingredient is the humic acids. Mined lignins are used primarily as thinners. which mayor may not be chemically modified;however, they are also widely used as emulsifiers.

n: the drilling fluid organic treating agent that reacted by humic acid and potassium hydrate.

n: kalium based drilling fluid that the kalium ion comes from humic acid potassium.
