Zinc, unwrought

cpc code 41442 covers the industry of producing unwrought zinc, a non-ferrous metal with a wide range of industrial applications. Zinc is an essential component in the manufacturing of various products, from galvanized steel to brass alloys, making it a crucial material in construction, automotive, and numerous other sectors. As a versatile and abundant resource, the global trade and production of unwrought zinc play a significant role in the broader economy.

The primary production technique for unwrought zinc involves the pyrometallurgical process, which includes smelting zinc-containing ores, concentrates, or secondary materials to extract the pure metal. This process typically involves roasting, leaching, and electrolytic or distillation methods to refine the zinc to the desired purity levels.

The main inputs required for the production of unwrought zinc include zinc-bearing ores, such as sphalerite and smithsonite, as well as various secondary sources, such as zinc-containing scrap and dust. Additionally, the production process requires significant energy inputs, typically in the form of electricity and fuel, as well as specialized equipment and machinery for smelting, refining, and casting the final product.

The primary output of cpc code 41442 is unwrought zinc, which can be further processed and used as an input for a wide range of industries. Some of the main consumers of unwrought zinc include the 41443 Zinc, in dust or powder form, 41444 Zinc, in plates, sheets, strip or foil, and 41445 Zinc, in bars, rods, profiles and wire industries, as well as the production of various zinc-based alloys and compounds.
