Hematite and magnetite are both iron oxide minerals, but magnetic hematite, though containing iron, is a manufactured ceramic material that is marketed and sold for its silvery appearance and magnetic …
Main Difference – Magnetite vs Hematite. A mineral deposit is a naturally occurring deposit that is unusually rich with a particular mineral. If a mineral deposit is composed of a metal that can be extracted using existing technological methods, then it is called an ore.
Hematine or "magnetic hematite" is a synthetic, magnetic simulant with a misleading name. Although its streak is red, the magnetism exposes it. Gem carvers can …
The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. Hematite is the most important iron ore.

As another difference between magnetite and hematite, hematite is a component of rust, but magnetite is not. Moreover, when considering the magnetic properties of the two minerals, magnetite is a naturally strong magnet, but in hematite, magnetism occurs upon heating. In addition to that, one other difference between magnetite and hematite is their structure. Hematite has a …
• Magnetite has higher iron content than hematite. • Magnetite is a naturally strong magnet. • Hematite has a rhombododecahedral crystal structure. Magnetite commonly shows octrahedral crystal structure. • Magnetite has a black streak. • Magnetite iron is in +2 and +3 oxidation states whereas. it is only in +3 oxidation state.
Mineralogy: magnetite & hematite – minerals of the … · The first mineral on our tour was quartz. Most weeks, we'll only cover one mineral, but there was a very strong push to include magnetite & hematite when I polled the blogosphere, so I chose to add both.
Magnetic techniques are suitable to detect iron oxides even in trace concentrations. However, since several iron oxides may be simultaneously present in natural and synthetic samples, mixtures of magnetic particles and magnetic interactions between grains can complicate magnetic signatures.
