REFINING OF PRECIOUS METALS

The purpose of precious metal refining is to extract and purify gold, silver, platinum, and other valuable metals from various sources such as industrial by-products, electronic waste, jewelry, and other metal alloys.

During the process, impurities are removed, and the final product is refined to a purity level suitable for industrial, jewelry, and financial applications.

THE REFINING PROCESS

  1. Analysis and Pre-treatment of Input Materials
    • Laboratory examination of customer-supplied materials.
    • Determination of composition and precious metal content using modern analytical methods (XRF, ICP-OES, gravimetric analysis).
    • Mechanical and chemical pre-treatment for more efficient processing (crushing, melting, solvent pre-treatment).
  2. Refining Technologies
    • Pyrometallurgical processes: melting at high temperatures and separation by oxidation.
    • Hydrometallurgical processes: acid and alkaline leaching, electrolysis, chemical precipitation.
    • Electrorefining: selection of pure metal via electrochemical methods.
    • Ion-exchange and filtration methods: combination of chemical and mechanical techniques to achieve the highest purity.
  3. Purity Control and Quality Assurance
    • Verification of refined metal purity through multiple analyses.
    • Certification of compliance with international standards (e.g., LBMA, ASTM, ISO).
    • Provision of certificates and reports to customers.
  4. Final Product Preparation and Delivery
    • Casting into standard bars, granules, or custom shapes according to customer requirements.
    • Packaging and secure transportation.
    • Optional reprocessing or other customized services.
