From coal a new source of rare earths

From coal a new source of rare earths

Lignite, which is found in North Dakota and Texas, is the youngest type of coal. Young coal contains a lot of organic acids called humic acids, which chelate metals and rare earths. But over time, the humic acid concentrations in coal drop, and the rare earths get incorporated into aluminosilicate clays.
