Precious metal recycling – find manufacturers and suppliers

Precious metal recycling is a process in which precious metals are recovered from used materials and waste in order to reintroduce them into the economic cycle

This practice is not only important for environmental and economic reasons, but is also an essential part of the circular economy as it reduces the need to mine new precious metals.

Below you will find an overview of the sources of precious metals and the processes of precious metal recycling, as well as the environmental benefits resulting from its use:

Sources of precious metals for recycling:

Precious metals can be recovered from a variety of sources.

1. Old jewelry and coins:
   Scrap gold, silver and other precious metals from old jewelry, coins and other items.
2. Electronic waste:
   Old or broken electronic devices such as cell phones, computers, televisions, circuit boards and batteries often contain small amounts of precious metals such as gold, silver and platinum.
3. Industrial waste:
   Various industries, such as the automotive industry or aviation, produce waste containing precious metals (e.g. catalytic converters containing platinum and palladium).
4. Dental gold:
   Dental gold from old tooth replacement materials and other dental applications.
5. Photography and medicine:
   In the past, certain precious metals were used in photography and medical devices, which are often recycled today.

Precious metal recycling processes:

Precious metals recycling involves several steps that can vary depending on the type of waste and material used.

1. Collection and pre-treatment:
   First, the materials must be collected and cleaned to remove impurities and other unwanted substances. This can be done by mechanical processes such as shredding or by chemical pre-treatment.
2. Shredding and separation:
   The materials are often mechanically shredded to separate the precious metals from other components. For electronic waste, this may include dismantling the equipment and extracting circuit boards and metal parts.
3. Pyrometallurgical processes:
   Fire gilding (pyrometallurgy):
   This involves melting the waste in furnaces and using temperature differences to separate the precious metals from other metals. This method is often used for gold and silver.
4. Leaching process (hydrometallurgy):
   Chemical solutions are used to extract the precious metals from the waste. A well-known process is cyanide leaching for gold, in which gold is extracted from the ore using cyanide solutions.
5. Electrolysis process:
   In some cases, electrolysis is used to separate precious metals from other materials. In electrolysis, an electric current is passed through a solution, causing the precious metals to be deposited on electrodes.
6. Mechanical processes:
   These involve crushing and grinding materials to extract precious metals. This can be done in combination with other processes such as sieving, magnets or X-ray fluorescence analysis to separate the precious metals from other substances.
7. Biotechnological processes:
   Recent research has shown that microorganisms such as bacteria and fungi can be used to extract precious metals by dissolving metal compounds from waste. This could provide a more environmentally friendly method for recycling precious metals.
8. Refinement and purity:
   After extraction and separation, precious metals often require further processing to increase their purity. This is done by refining, in which impurities are removed by chemical or physical processes. The resulting material has a very high purity and can be further processed into various forms (e.g. bars, wire, coins).
9. Reuse and sale:
   The recycled precious metals can now be used in new products. They are often used for the production of jewelry, coins, medals or in the electronics industry.

Use of precious metal recycling:

Precious metal recycling has a variety of uses and benefits, both economically and environmentally.

1. Industrial use:
One of the largest sectors for recycling precious metals is the electronics industry. Electronic devices such as smartphones, computers, televisions and other appliances often contain valuable precious metals such as gold, silver, palladium and platinum that can be recycled.

2. Jewelry industry:
Recycling old gold and silver plays an important role in jewelry manufacturing. Gold and silver from old pieces of jewelry can be recycled and used in new designs.

3. Automotive industry:
Platinum, palladium and rhodium in particular are used in catalytic converters in cars. These precious metals are known for their ability to reduce harmful emissions and can be recycled after use.

4. Medicine and dentistry:
In dentistry, precious metals such as gold and platinum are used for dental fillings and bridges. Precious metals are also used in medical devices, which can be recycled at the end of their service life.

Environmental benefits of precious metal recycling:

• Mining precious metals can be harmful to the environment, especially due to the use of toxic chemicals and mining in fragile ecosystems. Recycling reduces the need for mining and helps to reduce the environmental impact.
• The recovery of precious metals from waste is often less energy-intensive than the mining and processing of primary raw materials. This leads to a reduction in CO₂ emissions and a more efficient use of resources.
• Recycling precious metals is more cost-effective than mining new raw materials, especially when the high price and resource costs are taken into account.
• As precious metals are relatively rare, recycling helps to extend the life of these valuable resources and ensures that they remain available for future generations.

Precious metal recycling is an important process for the sustainable use of resources and the reduction of environmental impact. It not only offers economic benefits through the recovery of valuable metals, but also plays a crucial role in the transition to a circular economy. The various recycling methods and processes used in the industry help to reduce the need for primary raw materials and make precious metals efficiently reusable.
