Recycle Gold Plated Circuit Boards
In chemical equipment, gold plating on gold plated circuit board for temperature, pressure, flow sensors, and control modules has high conductivity. This ensures stable signal transmission. The gold plating on electrodes in pH sensors resists corrosion from acids and alkalis, extending service life to over 5 years. Because the gold plating of the gold plated circuit board has surface roughness <0.1μm and is oxidation-resistant, it's also used in circuit connection parts for chemical analysis instruments.
1. Used precious metal catalysts scrap: We explain precious metal catalyst recycling in detail on our Offshore Engineering Solutions page and Pharmaceutical Plant Solutions page.
2. Titanium Anode Electrode Materials used in hydrogen production by electrolysis and the chlor-alkali industry. Titanium is a rare, non-renewable precious metal with high recycling value. See our Titanium Anode Recycling Service page for details.
3. Iridium Platinum Alloy Valves from chemical reactors, pipelines, and other parts resistant to strong acid corrosion are also high-value precious metal components for recycling.
Important note: DONGSHENG Precious Metal Recycling Companies does NOT recycle industrial slag or tailings!
