Hematite is iron oxide, which is heavy and hard. Hematite contains 70% iron and can be produced in large quantities, so it is the most important iron ore. Hematite is named for its crimson color.
Hematite deposits are widely distributed, and hematite can be generated in many cases, but the most important hematite deposits are deposited. Hematite is usually produced with magnetite. In addition to ironmaking, powdered hematite is also used as a red pigment and abrasive.
The use of hematite in life: making jewelry and coloring.
Another name for hematite is iron oxide, because the chemical composition of hematite includes iron and oxygen, which is extracted from hematite and used for industrial purposes. Metallurgists remove oxygen from hematite until only iron remains.
Although iron can always be mined by itself, it gives industrial workers more iron to work and can also prevent miners from mining too much clean iron. Most iron is also combined with another substance, such as hematite, so it is very natural and expected by metallurgists.
Hematite uses:
Although hematite is not a more expensive substance, another use of hematite is in jewelry. These jewels are usually not designed for high prices, but more for beauty.
Hematite usually comes in many colors, including black, red and brown, which enables jewelers to make many different appearances from hematite. Many modern pigments use hematite to make luster, but these pigments are usually used in pigments, and some pigments use natural substances, such as hematite.
Although hematite has many different colors, it usually produces a light red paint color when crushed. After crushing, hematite will be added to oil, acrylic acid or other common paint substances. One of the purposes of this process is to color pigments, and it can also be used with fabrics to dye shirts, pants and other clothes.
