Copper mattes; cement copper (precipitated copper)

HS code 740100 covers copper mattes and cement copper, which are important intermediate products in the copper production industry. Copper is a vital metal used in a wide range of applications, from electrical wiring and plumbing to electronics and construction. The copper industry plays a crucial role in the global economy, supporting various downstream industries and contributing to economic development worldwide.

Copper mattes are produced by smelting copper ore concentrates, which involves heating the ore to high temperatures to extract the copper. The resulting copper matte is then further refined to produce pure copper. Cement copper, on the other hand, is produced through a chemical precipitation process, where copper ions in a solution are precipitated out as solid copper metal.

The production of copper mattes and cement copper requires several key inputs, including copper ore concentrates, smelting furnaces, and chemical reagents for the precipitation process. Additionally, energy sources, such as electricity or natural gas, are needed to power the smelting and refining operations. Specialized machinery and equipment, such as conveyor belts, crushers, and reactors, are also essential for the efficient processing of these copper intermediates.

Copper mattes and cement copper are important inputs for the production of refined copper, which is classified under [nc_link(740311)(Copper, refined)) and 740312 Copper, refined, in the form of wire. These refined copper products are then used in a wide range of downstream industries, including electrical and electronic equipment, construction, transportation, and consumer goods.
