Steel and other metallurgy

steelCalcium Oxide is added to converters (AOD) and electrical arc furnaces (EAF) as a flux and slagging agent to remove the impurities that can have an adverse effect on the quality of the metal (sulphur and phosphor).

We supply high-purity, highly reactive quicklime to achieve an optimum performance.

In the production of copper, zinc, lead, silver, nickel, gold, uranium, etc., Calcium Oxide is used, firstly to separate impurities by flotation of the different metal salts and secondly as a pH regulator of the water used throughout the manufacturing process.

In the production of aluminum, quicklime is used which acts as a slagging agent of silica, preventing the formation of aluminum and silicon compounds.
