How does Circle PGM handle logistics?

Circle PGM works with long term logistics partners across the globe. This ensures trustworthy and secure shipments

What materials can Circle PGM recover?

We handle a wide variety of materials containing precious metals (PGMs) in all shapes and sizes. Our specialty lies in iridium and ruthenium coated materials, which we process using our unique, chemical-free method.

Is Circle PGM compliant with European environmental regulations?

Yes, Circle PGM is compliant with European environmental regulations. Our innovative, chemical-free recovery process aligns with the standards for sustainability, safety, and environmental protection. We continue to improve on a daily basis.

What materials can be recovered and refined?

If your material contains precious metals, recovery is possible, even from very low concentrations. Whether it involves coated materials, solids, liquids, hazardous substances, organics, catalysts, or any other form shape or size, our team is here to assist you. Feel free to get in touch with us!

What’s the difference between destructive and non-destructive coating removal?

Destructive coating removal breaks down both the coating and the substrate, making the substrate unusable. Non-destructive removal, however, separates the coating while preserving the substrate, allowing it to be reused. At Circle PGM, we specialize in non-destructive, chemical-free method to recover precious metals sustainably

Let’s develop the right chemistry together.

Every application has unique technical requirements. Whether you require Iridium(III) Chloride or Hexachloroiridic Acid, our team works with you to define the right product specification, purity, concentration and supply programme. From material qualification to long-term sourcing, we support reliable and consistent iridium chemistry for demanding industrial applications.
