smelting plant for calcium

Smelting - WikipediaSmelting is a process of applying heat to ore in order to melt out a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases.90 MW Calcium Carbide Furnaces - HatchDeliver key technology components, including 90 MW calcium carbide furnaces, dry carbon monoxide off-gas systems, and automated mechanical handling systems for the molten calcium carbide product.
