Copper mattes; cement copper (precipitated copper)

HS v2017 Code: 7401

About copper mattes; cement copper (precipitated copper)

HS code 7401 covers copper mattes and cement copper, which are important intermediate products in the copper production industry. Copper is a vital metal for a wide range of applications, from electrical wiring and electronics to construction and transportation. The copper industry plays a crucial role in the global economy, supporting various downstream industries and contributing to economic development worldwide.

Production process

Copper mattes are produced by smelting copper-bearing ores, concentrates, or other copper-containing materials. The smelting process involves heating the raw materials to high temperatures, which separates the copper from impurities and other metals. Cement copper, on the other hand, is produced by precipitating copper from copper-containing solutions, typically through a chemical reaction with iron.

Production inputs

The production of copper mattes and cement copper requires several key inputs, including copper-bearing ores, concentrates, or other copper-containing materials, as well as energy sources (such as coal or natural gas) for the smelting process. Additionally, specialized equipment and machinery, such as smelters, furnaces, and precipitation tanks, are essential for the various stages of production.

Production outputs

The primary outputs of HS code 7401 are copper mattes and cement copper, which are then further processed to produce refined copper 7402 Unrefined copper; copper anodes for electrolytic refining and other copper products. These intermediate copper products are consumed by a wide range of industries, including 7403 Refined copper and copper alloys, unwrought, 7404 Copper waste and scrap, and 7405 Master alloys of copper, among others.
