How To Extract Platinum From Catalytic Converter

How to extract platinum from catalytic converters has become an increasingly popular topic in recent years, as the value of platinum has soared. In this blog post, we will explore the process of extracting platinum from catalytic converters, examine the tools and equipment needed, and discuss the environmental and legal aspects of this endeavor. We will also provide answers to some frequently asked questions on the subject.

Catalytic Converters

Catalytic converters are an essential component in the exhaust system of vehicles, primarily tasked with reducing harmful emissions. They work by converting toxic gases, such as carbon monoxide, nitrogen oxides, and hydrocarbons, into less harmful substances like water, carbon dioxide, and nitrogen gas. The conversion process is made possible by the use of precious metals, including platinum, palladium, and rhodium, which act as catalysts.

Why is Platinum Valuable

Platinum is a precious metal that is both rare and highly valuable. It is used in various applications, including:

  • Automotive industry: As mentioned above, platinum is a crucial component in catalytic converters.
  • Jewelry: Platinum’s durability, luster, and hypoallergenic properties make it popular for high-end jewelry.
  • Electronics: Its high conductivity and resistance to corrosion make it ideal for use in electronic components.
  • Medicine: Platinum is used in cancer treatments and pacemakers.
  • Investment: As a precious metal, platinum is often purchased as an investment in the form of bars, coins, and exchange-traded funds.

Given its wide range of applications and scarcity, platinum’s value has increased significantly over time.

Tools and Equipment Needed for Platinum Extraction

To extract platinum from catalytic converters, you will need the following tools and equipment:

  • Protective gear: Safety goggles, gloves, and a respirator or dust mask are essential to protect against hazardous materials.
  • Hammer or mallet: To break open the catalytic converter and expose the internal honeycomb structure.
  • Chisel: To remove the honeycomb material from the casing.
  • Container: To collect the extracted honeycomb material.
  • Filter or sieve: To separate the precious metal-containing dust from larger debris.
  • Acid treatment: A mixture of hydrochloric acid and nitric acid (aqua regia) is used to dissolve the platinum group metals.
  • Glassware: Beakers, flasks, and other glassware are needed for the chemical reactions and separation processes.
  • Heating equipment: A hot plate or burner is necessary for heating the chemical solutions.
  • Precipitating agent: To recover the dissolved platinum from the solution.

The Extraction Process

The process of extracting platinum from catalytic converters involves the following steps:

  • Dismantle the catalytic converter: Begin by removing the catalytic converter from the vehicle and then use a hammer or mallet to break open the casing.
  • Extract the honeycomb material: Use a chisel to carefully remove the honeycomb structure from the casing, and collect it in a container.
  • Crush and filter the material: Crush the honeycomb material into a fine powder, and then pass it through a filter or sieve to separate the precious metal-containing dust from larger debris.
  • Dissolve the platinum: Create a solution of aqua regia by mixing hydrochloric acid and nitric acid. Add the filtered dust to this solution, which will dissolve the platinum group metals. Ensure you are working in a well-ventilated area, as the process will release toxic fumes.
  • 5. Separate platinum from other metals: After allowing the solution to dissolve the platinum group metals, carefully decant or filter the solution to remove any undissolved solids. You may need to perform additional separation techniques to isolate the platinum from other dissolved metals, such as palladium and rhodium.
  • Precipitate the platinum: Add a precipitating agent, such as ammonium chloride, to the solution. This will cause the dissolved platinum to form solid particles that can be easily collected.
  • Filter and wash the precipitate: Use a filter to collect the solid platinum particles, and then wash them with distilled water to remove any residual chemicals.
  • Dry and melt the platinum: Allow the filtered platinum particles to dry completely. Once dry, the platinum can be melted down and formed into ingots, bars, or other desired shapes.

Safety and Environmental Considerations

Extracting platinum from catalytic converters involves working with hazardous materials and chemicals. It is crucial to follow proper safety precautions, such as wearing protective gear and working in a well-ventilated area. Additionally, the disposal of chemical waste must be done according to local regulations to prevent environmental harm.

Legal Aspects of Extracting Platinum

Before attempting to extract platinum from catalytic converters, it is essential to understand the legal implications. In many jurisdictions, it is illegal to remove or tamper with catalytic converters unless you are a licensed recycler or have obtained the necessary permits. Furthermore, extracting platinum from stolen catalytic converters can result in criminal charges. Always check local regulations and ensure you are operating within the law.


Can I extract other precious metals from catalytic converters?

Yes, catalytic converters also contain palladium and rhodium, which can be extracted using similar methods.

How much platinum can I expect to recover from a catalytic converter?

The amount of platinum in a catalytic converter varies depending on the make and model of the vehicle. On average, you can expect to recover between 1 to 2 grams of platinum per catalytic converter.

Is it profitable to extract platinum from catalytic converters?

The profitability depends on factors such as the current market price of platinum, the quantity of converters processed, and the efficiency of the extraction process. It can be profitable, but it is essential to consider the costs of equipment, chemicals, and safety measures.

Can I sell my catalytic converter without extracting the platinum?

Yes, many recycling facilities and scrap yards will purchase whole catalytic converters based on the value of the precious metals contained within.

Is it legal to remove a catalytic converter from a vehicle?

In many jurisdictions, it is illegal to remove or tamper with a catalytic converter unless you are a licensed recycler or have obtained the necessary permits. Always check local regulations before attempting removal.

How do I determine the value of a catalytic converter?

The value of a catalytic converter is primarily determined by the quantity and market price of the precious metals it contains. The make, model, and age of the vehicle can also impact the value.

Can I extract platinum from other sources besides catalytic converters?

Yes, platinum can also be found in jewelry, electronics, and other industrial applications. However, the process of extracting platinum from these sources may differ from that of catalytic converters.

What are the risks involved in extracting platinum from catalytic converters?

The primary risks include exposure to hazardous materials and chemicals, potential legal issues, and environmental concerns. Proper safety precautions, compliance with local regulations, and responsible waste disposal are essential to mitigate these risks.

Final Words

Extracting platinum from catalytic converters is a complex and potentially hazardous process. It is crucial to understand the various aspects involved, including the tools and equipment needed, the extraction process itself, and the safety, environmental, and legal considerations. While it can be a profitable endeavor, it is essential to approach the process with caution and respect for the potential risks. If you are unsure about any aspect of the extraction process, consulting with a professional or selling the catalytic converters to a licensed recycling facility may be a safer and more responsible option.
