Montan wax
From Wikipedia, the free encyclopedia
Montan wax, also known as lignite wax or OP wax, is a hard wax obtained by solvent extraction of certain types of lignite or brown coal.[1] Commercially viable deposits exist in only a few locations, including Amsdorf, Germany, and in the Ione Basin near Ione, California. High-graded lignite wax are also found in Yunnan and Jilin, China.
