Copper: From Ore to Finished Products

1. Copper Ore and Raw Materials
Copper begins as ore, mainly composed of copper sulfide and oxide, extracted through mining. The raw ore is crushed, and impurities are removed during smelting, producing copper concentrates. These concentrates contain a high percentage of copper, ready for refining.

2. Metal Smelting and Refining
In the smelting process, copper concentrates are heated in furnaces to separate copper from impurities. The molten copper is then further purified through electrorefining, producing high-quality copper cathodes, which are essential for creating copper products.

3. Manufacturing and Casting
Refined copper is melted and cast into billets, rods, or ingots, which are then processed into products like pipes, sheets, and wire. Copper’s excellent conductivity and malleability make it ideal for use in electrical, plumbing, and industrial applications, often alloyed to enhance specific properties.

Properties and Appearance of Copper
Copper is an element with the symbol Cu. It is a red, soft, malleable, and highly ductile metal. It is one of the best electrical conductors among common metals and is also a good thermal conductor, effectively transferring heat. Copper can easily be formed into various shapes through rolling, drawing, and hammering. It has antibacterial properties, capable of killing bacteria and viruses on its surface.

Ultra-Pure Copper Products
Suitable for the most demanding applications that require the highest purity copper.

It all starts with high-purity copper
Even small impurities can have a significant negative impact on the intended results, which is why we never compromise on the purity of raw materials. Our finished and semi-finished products are made from the highest purity copper.

We use only the highest-quality cathodes to produce our proprietary oxygen-free copper. This vertical integration allows us to fully control the quality and supply of both raw materials and products.
