Cleavage / fracture. Cleavage and fracture describe different ways in which a mineral can break. Definitions. Cleavage The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice. These twodimensional surfaces are known as cleavage planes and are caused by the alignment of weaker bonds between atoms in the crystal lattice.

Jan 28, 2012 · Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. This is the key difference between magnetite and hematite. Moreover, magnetite has higher iron content than hematite therefore, its quality is higher. Apart from that, in colours too, there is a difference between magnetite and hematite.

There are eight major diagnostic properties of minerals: crystal habit, luster, hardness, cleavage, fracture, color, streak, and specific gravity. Generally, there is no single diagnostic property which, by itself, can be used to identify a mineral sample. Rather, we must rely on a number of diagnostic properties to reach this goal.

Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.

Magnetite is the primary oxide of iron found in meteorites (and thus presumably in asteroids). Thermite is a mixture of powdered magnetite and powdered aluminum. When ignited, the aluminum fuel burns using the magnetite as an oxidizer, resulting in much heat, aluminum oxide (corundum), and molten iron.

Cleavage: There is no cleavage. Magnetite may show some parting, which is a break along structural planes and is parallel to a possible face, just like cleavage. Fracture: Magnetite has a SubConchoidal Fracture, meaning it''s smooth with irregular rounded corners. There can also be breakage that resembles concentric ripples.

Sphalerite is the most important ore of zinc. Around 95% of all primary zinc is extracted from sphaleritic ores. However, due to its variable trace element content, sphalerite is also an important source of several other elements, such as cadmium,, gallium germanium, and indium.

Magnetite rarely occurs in the form of colloform aggregates. Synthesized magnetite is widely used in industry. It is usually obtained by synthesis in the solid phase following the combined roasting of pressed FeO and Fe 2 O 3 powders at temperatures of 10001400°C. Magnetite is brittle with an uneven fracture it exhibits no cleavage.
