The Value of Platinum in Spark Plugs: Recycling Solutions by Dingfeng Precious Metals

Platinum spark plugs dominate the OEM market due to their corrosion resistance and efficiency. However, mining platinum requires processing 10 tons of ore for just 1 ounce of metal.

Why Recycle?

• Price Stability: Platinum trades at $900\text{–}$1,200 per ounce—recycling offsets market volatility.

• Purity Standards: Dingfeng’s reclaimed platinum meets ISO 9001-certified purity levels for reuse in:

• Catalytic converters (50% of demand).

• Lab equipment and jewelry.

Technical Process

1. Crushing: Spark plugs are pulverized to separate ceramic insulators from metal electrodes.

2. Acid Leaching: Platinum is dissolved using a nitric acid-hydrochloric acid blend.

3. Precipitation: Platinum is extracted as a salt and reduced to pure metal.

Client Success
