Copper mattes; cement copper

cpc code 41411 covers the production of copper mattes and cement copper, which are important intermediate products in the copper smelting and refining 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 industries such as 41412 Copper, unrefined; copper anodes for electrolytic refining, 41413 Refined copper and copper alloys, unwrought, and 41414 Copper and copper alloy waste and scrap.

Copper mattes are produced by smelting copper-containing ores, concentrates, or other raw materials in a furnace. The smelting process involves the reduction of copper sulfides to produce a molten copper-iron-sulfur mixture, known as copper matte. Cement copper, on the other hand, is produced by the precipitation of copper from copper-containing solutions, typically through the use of iron or other reducing agents.

The main inputs for the production of copper mattes and cement copper include copper-containing ores, concentrates, and other raw materials, as well as energy sources, such as coal or natural gas, to power the smelting and refining processes. Additionally, the industry requires specialized equipment, such as furnaces, reactors, and precipitation tanks, as well as skilled labor to operate the production facilities.

The primary outputs of cpc code 41411 are copper mattes and cement copper, which are then further processed and refined to produce pure copper and copper alloys. These intermediate products are consumed by industries such as 41412 Copper, unrefined; copper anodes for electrolytic refining, 41413 Refined copper and copper alloy, unwrought, and 41414 Copper and copper alloy waste and scrap, which use them as inputs for their own production processes.
