Today, geologists can study the magnetic properties of rocks of various age and reconstruct the history of change in Earth's magnetic field. This preserves the orientation of Earth's magnetic field within the rock at the moment of crystallization. In the crystallization of an igneous rock, tiny crystals of magnetite form in the melt, and because they are magnetic, they orient themselves with the direction and polarity of Earth's magnetic field. Tiny crystals of magnetite are present in many rocks. Small amounts of magnetite are also used as a toner in electrophotography, as a micronutrient in fertilizers, as a pigment in paints, and as an aggregate in high-density concrete. In the past few decades, synthetic abrasives have filled many of the applications where magnetite was previously used. Some finely ground magnetite is also used as an abrasive in waterjet cutting.
The production of synthetic emery gives the manufacturer control over the particle size and the relative abundance of aluminum oxide and magnetite in the product. Some synthetic emery is produced by mixing magnetite with aluminum oxide particles. ergo ergodic erh eri eric eric0 eric1 eric2 eric3 eric4 eric5 eric6 eric7 eric8.

The abrasive known as "emery" is a natural mixture of magnetite and corundum. Regan Rege Regina Regina1 Reginald Registration Rehmann Reich Reid Reif. They can be directly loaded into a blast furnace at a mill and be used to produce iron or steel. These pellets are easy to handle and transport by ship, rail, or truck. The concentrate is then mixed with small amounts of limestone and clay, then rolled into small round pellets. Today's commercial taconites contain 25 to 30% iron by weight.Īt the mine site, the taconite ore is ground to a fine powder, and strong magnets are used to separate magnetically susceptible particles containing magnetite and hematite from the chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Creative Commons photo by Harvey Henkelmann. The pellets are approximately 10 millimeters in diameter. Taconite pellets: These red spheres are taconite pellets that are ready to ship to a steel mill.
