Chromite
Chromite, also known as chrome ironstone or chrome iron ore, is a common mineral from the spinel group within the mineral class of “oxides and hydroxides”.
The melting point of chromite is over 2140 °C. It is generally non-magnetic, although it can usually exhibit magnetism when heated.
Chromite is one of the main components for obtaining chromium (chemical element chromium) and is used to produce stainless steel and to refine surfaces by chrome plating.
Ilmenite
Ilmenite also known as titanium iron or titanium iron ore is a common mineral from the mineral class of oxides and hydroxides. It crystalizes in the trigonal crystal system with the chemical composition FeTiO3 and usually develops thick-table crystals, but also granular to massive aggregates in a black to steel-gray color.
Ilmenite is one of the main raw materials for the production of titanium dioxide by both the chloride process and the sulfate process. It is mostly used to make pigments, cosmetics, medicines, paper, polymers and glass.
Manganese
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a silver-white, hard, very brittle transition metal that is similar to iron in some properties.
90% of the mined manganese is used in the steel industry in the form of ferromanganese as an alloying component of steel. It removes oxygen and sulfur from the steel and at the same time improves hardening.
In general, manganese in steel increases hardenability and nitridability, tensile strength, yield strength and hot formability.
Nickel
Nickel is one of the transition metals with the chemical symbol Ni. It is a silvery, ductile, ferromagnetic metal with a brass-like sheen.
It is an important component in the production of stainless steel and is mainly used for alloys. In small quantities as metal, most of the production goes to the manufacture of stainless steel and nickel alloys. As an alloy metal for steel refining, it makes the steel corrosion-resistant and increases its hardness, toughness and ductility.
The resulting alloys are often used as catalysts for hydrogenation reactions.
Vanadium
Vanadium with the chemical symbol V is a steel-gray shimmering, very soft transition metal in its pure state and is mainly used in steel production as ferrovanadium.
The special characteristics of vanadium lead to an increase in toughness and thus increased resistance of the steel. Over 90% of production is used in a variety of alloys, mostly with the metals iron, titanium, nickel, chromium, aluminum or manganese.
Titanium alloys, which contain vanadium and usually aluminum, are particularly stable and heat-resistant and are used in aircraft construction for load-bearing parts and turbine blades of aircraft engines.
