Magnetic Hematite Vs. Hematite Mineralogy Geology | eHow

People might assume that magnetic hematite is simply "magnetized" hematite. True hematite, though iron-containing, actually has a weak magnetic field because of the way its iron atoms are aligned. On the other hand, the mineral magnetite is highly magnetic, and many often erroneously assume it is magnetic hematite (the artificial material).

Hematite: A primary ore of iron and a pigment mineral

Uses of Hematite (Iron Ore) Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

Black Sands Processing « TCB Metals and Refining

We Process Black Sands. Due to the heavy iron content of black sands, most processors, smelters and refineries are unable to process them. We have a unique chemistry that allows us to aggressively process precious metals at 20 mesh and below in less than one hour, so we can effectively leach black sands without dissolving the majority of their iron content.
