Others

These are metals widely used in various industries, such as silicon metal, substituted copper, and coal. Special metals are exported/imported, and are difficult to obtain as rare metals, so they are purchased a lot and produced in small quantities.

Silicon Metal

It is a raw material widely used in various industries such as semiconductor, alloy, and organic silicon industries. According to the current status of metal silicon production as of 2010, China accounts for 53% of the world's production with a total output of 1,049,000 tons. It is made by dissolving/reducing silicon and carbon extracted from mines, and is the main raw material for manufacturing polysilicon, a key raw material for semiconductors and solar materials, and is widely used in alloys, chemicals, and organic silicon.

Copper

It is a high-purity copper product used as a raw material for various industries in forms such as heavy metals and glass acids. The purity is high, the particle distribution is even, the iron content is low, and other heavy metals and free acids are low. In addition, it is a metal solid with reddish brown gloss and has excellent conductivity, ductility, and processability. Heat and electrical conductivity are the second largest after silver and react with humid air to produce rust.

Coltan

It is a rare metal with limited production, and contains tantalum, which is used as a key material for electronic devices such as mobile phones as well as electronic products. When processed with metal powder, it becomes a mineral called tantalum. With these characteristics of coltan, it is used as a material for various optical dispersion glass, color TV, cutting tools, various capacitors for electronic devices, medical equipment, and aircraft. It is produced in the United States, Australia, Brazil, Congo, Canada, and China. Among them, there are especially many in Congo, and 80% of the world's coltan is buried in the Democratic Republic of Congo.
