Item discription Precious Metals

Precious metals

Precious metal products are produced through the process based on waste liquids, waste resources, and concentrates containing gold (Au), silver (Ag), platinum (Pt), and palladium (Pd). These precious metal products are used as industrial materials or supplied domestically and internationally.

Gold

Gold is a shiny yellow soft metal, a soft, flexible transition metal, and it is not economical at all because the amount is very small and the cost of operating the accelerator is much higher. Therefore, all commonly used gold is still obtained from the land, so gold mining is a very important business. It is an ingot-type product that produces 99.99% pure gold products by repeated processing from electric and electronic scraps, waste liquids and plating amounts, and other scraps and by-products. These gold products are used for various purposes such as jewelry, electronic materials, and plating. In particular, gold mines in Africa have been developed to secure gold.

Silver

It is a soft, white, shiny transition metal that has superior electrical and thermal conductivity compared to other metals, so it is produced in silver ore or pure silver form, and is used for coins, ornaments, tableware, photographs, and silver medals. Silver mines are located in most countries. However, because it is expensive to dig out silver, many countries do not produce silver for economic reasons. Pure silver is very soft, so to increase the strength and hardness of silver, use a small amount of other metals.

Platinum

Platinum, the highest quality precious metal that is beautiful and doesn’t corrode, is the second most common element after palladium, is malleable, and has a high density, so it has a glossy silver white color. Pure platinum is ductile and full of potential. However, natural platinum is fragile, heavy, and flexible because it contains impurities, belongs to a class of transition metals, and is highly valuable. It is used for accessories, experimental equipment, electric outlets, medical devices, and automobile emission control devices.

Pallaidum

A silver-white rare transition metal belongs to the platinum group of elements, has similar chemical properties to platinum, is extracted from copper or nickel ore, and is mainly used as catalysts and ornaments. In addition, it is a silvery white glossy metal, similar in properties to platinum, and has the lowest melting point and density among the platinum elements. It has excellent ductility and conductivity and increases in strength at low temperatures. It is contained as an alloy in platinum, gold, and silver ore, and is easily alloyed with gold, and solid solution with platinum. It is used for various industrial purposes such as plating raw materials and catalyst manufacturing.
