What is Precious metal refining equipment?
Precious metal refining equipment is used to purify precious metals such as gold, silver, platinum, palladium, etc. from scrap, electronic waste, jewelry and industrial by-products. It removes impurities in precious metals through chemical methods (such as electrolytic refining) or physical methods (such as vacuum distillation) to improve the purity of metals. The purity reaches more than 99.9%, making it meet industrial or financial transaction standards.
✔ Fully Automated & Semi-Automatic Systems
✔ Some equipment (such as Hastelloy alloy furnace) adopts low temperature refining technology to reduce energy consumption and reduce pollution emissions.
✔ Compact & Scalable Solutions (Lab-Scale to Industrial)
Why Choose Our Precious metal refining equipment?
Precious metal refining equipment has outstanding refining capabilities in purifying rare metals such as gold, silver, platinum, and palladium. For example, chemical refining can make the purity of gold and silver reach 99.99%, and the recovery rate exceeds 99.9%; the Hastelloy alloy furnace adopts low-temperature refining technology, which reduces energy consumption and pollution emissions compared with traditional fire methods, and the vacuum induction melting furnace saves more than 60% energy. It has a high degree of automation, and the PLC control system realizes precise temperature control and full process automation, reduces manual intervention, and improves production efficiency. The equipment has strong adaptability and can process raw materials in different forms, such as gold mud, alloy waste, etc., and supports customized production.

What is the process flow of Precious metal refining equipment?
Precious metal refining equipmentThe process of purifying precious metals includes dissolution, filtration, precipitation, smelting and casting. Understanding the process will help us better choose equipment. The specific steps are as follows:
Dissolution: The raw metal is dissolved in high purity acid (Aqua Regia, Cyanide-Free).
Filtration: Impurities are removed from the metal using a filter press or filter press
Precipitation: Selective chemical agents isolate target metals.
Electrolysis/Cementation: Further purification via electrochemical methods.
Melting & Casting (Optional): Produces bars, grains, or custom shapes.
