Limonite (lim) | SpringerLink
The definition in the heading invites us to dispense with the classical concept of limonite as brown iron ore = Fe 2 O 3 ·1½ H 2 O (i.e. 2Fe 2 O 3 ·3H 2 O) and, by referring to a rock of hydrated iron oxides, hints at the great variety that can be found in limonites, a term discredited by IMA as a mineral species.However, since it can be both …
Understanding iron saturation and why it's important | Base
A certain percentage of the iron in your blood will bind to the transferrin, and then get transported to your organs. If your iron saturation is getting tested, the results should be within a reference range of 15% to 50% for men, and 10% to 45% for women. That said, sometimes low saturation doesn't mean low iron --- they are often, but not ...
