Precious metal refining services involve the process of purifying metals from raw materials containing precious metals - such as ores, industrial waste, and electronic scrap - through specialized techniques. The goal is to obtain high-purity gold, silver, platinum, palladium, and other metals. Its core function lies in enhancing metal value, meeting industrial standards, and promoting resource recycling. Based on processing scale, precious metal refining services fall into two categories: large-scale mining refining and small-to-medium-scale recycling refining. Large-scale operations typically employ electrolytic or high-temperature chlorination processes requiring substantial equipment investment, while smaller facilities rely on hydrometallurgy or eco-friendly refining machines, making them suitable for treating waste from jewelry, electronics, and other industries. The global precious metal refining services market is projected to reach $892 million by 2031, growing at a CAGR of 6.1%, underscoring its pivotal role in resource recycling.

Selecting precious metal refining services requires consideration of raw material type and priority needs. Jewelers or small workshops should prioritize providers offering micro-refining equipment. Such systems process 5–10 kilograms of material daily, achieving 99.9% purity with loss rates below 6‰, while ensuring zero exhaust emissions and compliant wastewater treatment. E-waste processors should focus on extraction technologies like chemical separation, which can refine gold and silver to 99.9% purity. Large mining enterprises should opt for high-temperature chlorination or electrolytic processes—though capital-intensive, these suit bulk processing. For refining industrial precious metal waste, DONGSHEGN Precious Metals Recycling is a reliable choice. Furthermore, certifications for refining service providers (e.g., LBMA certification) are crucial—for instance, Zhaojin Refining achieves 99.999% purity through automated BLD processes. Such suppliers gain greater recognition from banks and exchanges.
Refining precious metals from industrial waste requires addressing complex compositions and low recovery rates. For instance, spent catalysts from the petrochemical industry contain rare metals like platinum and rhodium, which can be purified to 99.99% purity via aqueous chloride leaching. DONGSHENG Precious Metals employs a segmented purification process capable of simultaneously treating eight precious metals, achieving purity exceeding 99.99% in a single step—surpassing the industry standard of secondary refining. For metallic waste (e.g., grinding powders), hydrometallurgy combined with exhaust gas treatment systems can boost recovery rates to over 95%. It is advisable to select precious metal refining service providers offering high recovery prices and low refining service fees to ensure sufficient profit margins.
Refining fees typically vary based on metal type, purity requirements, and processing complexity. Basic refining charges range from 3%–8% of recovered metal value. For instance, gold refining using oxalic acid reduction incurs additional reagent costs per kilogram. Highly complex waste (e.g., rhodium-containing solutions) may require multi-step extraction, raising fees to 10%–15%. Some precious metal refining companies adopt a “refining fee + testing fee” model, with testing fees fixed at $50–200 and refining fees charged per batch. Long-term partnerships may qualify for negotiated flat-rate fees; for instance, Linlan Company offers tiered discounts to clients with annual processing volumes exceeding 5,000 tons. It is advisable to compare providers' hidden costs (e.g., waste residue disposal fees) and prioritize precious metal refining services with transparent pricing.
Don't limit yourself to just precious metal refining services! Selling your precious metal scrap to a precious metal recycling company is an easier way to earn substantial profits.
