Our offered Product range includes smelting, PRIMARY NICKLE, stainless steel concentrates and stainless steel ore.
Smelting is a form of extractive metallurgy; its main use is to produce a metal from its ore. This includes production of silver, iron, copper and other base metals from their ores. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, or in earlier times charcoal. The carbon (or carbon monoxide derived from it) removes oxygen from the ore, leaving behind elemental metal. The carbon is thus oxidized in two stages, producing first carbon monoxide and then carbon dioxide. As most ores are impure, it is often necessary to use flux, such as limestone, to remove the accompanying rock gangue as slag.
Brief: In the mid 18 th century, primary nickel was first isolated as a separate metal. Prior to this, it was found in copper mines and thought to be an unmeltable copper ore. Primary nickel can resist corrosion and maintains its physical and mechanical properties even when placed under extreme temperatures. When these properties were recognized, the development of primary nickel began. It was found that by combining primary nickel with steel, even in small quantities, the durability and strength of the steel increased significantly as did its resistance to corrosion. This partnership has remained and the production of stainless steel is now the single largest consumer of primary nickel today. This highly useful metal is also used in the production of many different metal alloys for specialized use.
