Zinc Concentrate for Sale (Contact us for your buying requirement)
Zinc is a bluish-white, lustrous metal. It is brittle at ordinary temperatures but malleable at 100 to 150°C. It is a reasonable conductor of electricity, and burns in air at high red heat with evolution of white clouds of the oxide.
Zinc can be produced pyrometallurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Zinc concentration is in the range of 40–60%, with sulfur content in sulfidic ores in the range of 26–34%. Ores with a mixture of lead and zinc concentrate usually have lower respective metal concentrations. During sintering, a blast of hot air or oxygen is used to oxidize the sulfur present in the feed to sulfur dioxide (SO2).
Application:
Galvanizing is the process by which zinc is metallurgically bonded to steel, thereby giving the steel the most advanced and cost-effective anti-corrosion coating. Galvanized steel is used wherever corrosion is a threat.
Brass is a family of copper-zinc alloys. The zinc content of brass ranges from 10% to more than 40%. Besides its traditional use for door handles, lighting fixtures and decorative objects, brass is now an increasingly popular material with architects, interior designers and consumers.
The strength and fluidity of die-casting alloys based on high purity zinc make them ideal for thousands of die-casting applications, such as household appliances, precision parts for cars, computers and communications equipment.
