  • Iridium

    Auris Noble has an iridium refining process that yields a high purity water-soluble iridium product.

    Auris Noble has a proprietary process specifically designed for refining iridium. Iridium-containing material from our recovery processes is fed to our iridium refining process. This refining process utilizes advanced chemical methods for removal of undesirable contaminants to yield a highly pure iridium product.

  • Platinum

    Our platinum refining process yields a pure metallic platinum sponge from mixed metal concentrates and scrap materials.

    Platinum-containing materials from our recovery processes are refined by our unique platinum refining process.

  • Gold

    Auris Noble refines gold from various sources, including jewelry scrap, electronic waste, and industrial byproducts.

    With a focus on sustainability and efficiency, Auris Noble refines gold from various sources, including jewelry scrap, electronic waste, and industrial byproducts. Our state-of-the-art refining processes ensure the recovery of high-purity gold, suitable for re-use in manufacturing, investment, and technology applications.

  • Ruthenium

    We operate a ruthenium process that yields a high purity water-soluble ruthenium product.

    Auris Noble has a process specifically designed for purifying ruthenium. Ruthenium-containing material from our recovery processes is fed to the ruthenium refining process.

  • Palladium

    Auris Noble's palladium refining process yields a pure metallic palladium sponge.

    Palladium-containing materials from our recovery processes are refined by our palladium refining process.

  • Rhenium

    Auris Noble specializes in the recovery and refining of rhenium from aerospace scrap and superalloys.

    Our refining process ensures the production of high-purity rhenium for use in high-temperature turbine engines, electronics, and catalysts, contributing to advancements in materials technology. We produce a pure metallurgical grade rhenium pellet product from our rhenium refining process.
