Dolomite

It is a mineral composed of calcium and magnesium double carbonate. In the iron and steel industry, such as the pelletization of iron ore, the sintering process of iron production, the manufacture of calcined dolomite, the manufacture of dolomitic refractories, the glass industry and the sulfur dioxide generating industry, among others.

Limestone

It is a sedimentary rock composed mainly of calcium carbonate (CaCO3), with small amounts of minerals such as magnesite, clay, hematite, quartz, among others.

• • In process of iron ore smelting.
• • To reduce sulfur dioxide emissions from combustion products in thermoelectric plants.
• • For the manufacture of Ash Sodium Carbonate.
• • In the sugar industry as part of the purification process.
• • In the glass industry as a flux.

Quicklime (Sedolca)

Dolomitic lime resulting from the calcination of the dolomitic stone CaMg (CO3) 2, consisting especially of calcium oxide, magnesium oxide and other oxides.

• • In Electric Arc Furnaces (HEA) as MgO carrier and foamed slag former.
• • In the manufacture of refractory products.
• • To manufacture electrofused products.
• • To produce metallic magnesium and magnesite.

Slag Conditioner

Magnesite from its calcination to death at temperatures above 1500 ° C.

• • As a carrier of MgO in Electric Arc Furnaces (HEA).

Briquette Slag Conditioner

Caustic agglomerated magnesite, in briquettes in the form of a pillow, by pressure effect, developed in a roller press.

• • As a carrier of MgO in the Electric Arc Furnaces (HEA), saturating the slag with MgO during steelmaking.
• • Foam slag maker in Electric Arc Furnaces (HEA).

Olivine Sand

Raw material composed basically of olivine sand, with an adequate granulometric distribution and a high resistance to the operating temperature, which prevents sintering and allows to improve its fluidity in the casting pit - EBT.

• • It is used as filling material in the bottom casting (EBT) pouring holes of the electric arc furnaces.

Bentonite

It is a sodium bentonite or natural clay that contains a high portion of sodium montmorillonite.

• • As a binding agent in the production of iron pellets.
• • As a binder of quartz sand for casting molds.
• • Preparation of drilling muds from wells of water, oil and natural gas.
• • In civil engineering and foundations.
• • In the industry of detergents, paint, agriculture and wine, cosmetics, pharmaceutical, among others.
