Rhodium recovery_ Which fields have been applied to rhodium? What are the ways to recover rhodium?

Application fields of rhodium:

1. Automotive industry: Rhodium is used in automotive catalytic converters to reduce the emissions of harmful gases such as nitrogen oxides.

2. Jewelry industry: Rhodium is used for plating jewelry to enhance its durability and luster.

3. Chemical manufacturing: Rhodium is used as a catalyst in various chemical reactions, such as the production of acetic acid and Vinyl acetate.

4. Electrical industry: Rhodium is used for electrical contacts due to its high corrosion resistance and wear resistance.

5. Nuclear industry: rhodium is used as a Neutron flux detector in nuclear reactors.

6. Medical industry: Rhodium-103 and rhodium-105 are used for cancer treatment, especially close range radiation therapy.

Rhodium recovery pathway:

1. One of the most important sources of rhodium for recycling is spent car catalysts, which contain a small amount of metal. By converting harmful pollutants such as nitrogen oxides, carbon monoxide, and hydrocarbons into less harmful gases, rhodium is used in the catalytic converter to reduce vehicle exhaust emissions. This metal is a fundamental component of the three way catalyst used in gasoline engines and the diesel oxidation catalyst used in diesel engines. Catalyst manufacturers and recycling companies recycle, refine, and sell to the automotive industry for reuse, thereby reducing the demand for new mining and extraction.

2. Electronic waste is another source of rhodium used for recycling purposes. Electronic devices, such as smartphones, computers, and other electronic devices, contain a small amount of Rh in various components, including contacts and switches. Rhodium can be recovered from Electronic waste through a process called hydrometallurgy, which involves dissolving the metal in an acidic solution and extracting it in a pure form. Due to the high complexity of electronic devices and the need for specialized equipment, the recycling process may be challenging.

3. Another source of rhodium recycling is jewelry waste. This metal is a popular choice for jewelry, especially in the production of platinum, which is alloyed with other metals such as platinum, copper, and nickel to increase strength and durability. Jewelry manufacturers and retailers often collect and recycle scrap metals, including rhodium, to reduce waste and minimize the environmental impact of their operations.

Recycling rhodium has numerous environmental and economic benefits. Extracting rhodium from underground is a costly and energy intensive process that requires a large amount of water and energy. Recycling metals reduces the demand for new mining and extraction, protects natural resources, and reduces carbon dioxide emissions.
