Guanma Machinery PGM recovery refining plant manufacturers in China, supplying turnkey systems for recovering platinum, palladium, rhodium, ruthenium, iridium, and osmium from spent catalysts, e-waste, mining by-products, and other precious metal bearing materials.
What Is a PGM Recovery Refining Plant?
A PGM recovery refining plant is an integrated processing system designed to extract and purify platinum group metals from primary or secondary raw materials. The plant typically includes several stages:
- Feedstock preparation – crushing, milling, sampling, and homogenization
- Thermal treatment – incineration, roasting, or smelting to concentrate PGMs
- Leaching and dissolution – chemical digestion using aqua regia, chlorination, or other hydrometallurgical methods
- Separation and purification – solvent extraction, ion exchange, precipitation, or molecular recognition technology
- Final refining – reduction, calcination, or electrorefining to produce high-purity PGM sponge or ingot
- Environmental control – waste gas scrubbing, wastewater treatment, and solid residue management
PGM refining plant manufacturers in China can supply modular units for small-scale recyclers or large turnkey facilities with capacities ranging from a few kilograms to several tons of PGM-bearing feed per day.
Common PGM Feedstocks Processed by Refining Plants
When you contact PGM recovery refining plant manufacturers, you will usually be asked about your feedstock type. The plant design depends heavily on the material being processed. Common feedstocks include:
Spent Automotive Catalytic Converters
Catalytic converter recycling is one of the applications for PGM recovery plants. These plants recover platinum, palladium, and rhodium from ceramic or metallic honeycomb substrates. Manufacturers often supply complete catalytic converter recycling plants.
E-Waste and Electronic Scrap
Printed circuit boards, connectors, integrated circuits, and other electronic scrap contain small but valuable amounts of palladium, platinum, and sometimes rhodium. A dedicated e-waste precious metal refining plant can process these materials after mechanical pretreatment and base metal removal.
Spent Petrochemical and Chemical Catalysts
Refineries and chemical plants generate large quantities of spent catalysts containing platinum, palladium, and rhodium. PGM recovery refining plant manufacturers design specialized systems for alumina-supported, carbon-supported, and homogeneous catalyst residues.
Mining Concentrates and Anode Slime
Primary PGM producers and copper refineries process PGM-bearing concentrates, matte, and anode slime. These feedstocks often require more complex smelting and hydrometallurgical circuits, which many experienced Chinese manufacturers are capable of delivering.
How to Choose PGM Recovery Refining Plant Manufacturer
Selecting the right supplier is the most important decision in your project. Here are the key factors to evaluate:
1. Experience with Your Feedstock
Not all PGM refining plants are the same. A manufacturer with experience in catalytic converter recycling may not be the best choice for anode slime refining. Ask for case studies or references related to your specific feedstock.
2. Recovery Rate Guarantees
A reliable PGM refining plant manufacturer in China should provide recovery rate targets for platinum, palladium, and rhodium. Typical recovery rates for catalytic converters should exceed 97–99%, while complex e-waste or mining materials may have lower but clearly defined targets.
3. Pilot Testing and Process Validation
Before committing to a full-scale plant, ask whether the manufacturer offers laboratory or pilot-scale testing.
4. Custom Engineering and Modular Design
Your space, capacity, and budget will influence plant layout. Many manufacturers offer modular PGM refining plants that can be installed quickly and expanded later. Custom engineering should be available for unusual feedstocks or special purity requirements.
5. Environmental and Safety Compliance
Check whether the manufacturer’s design meets international standards for emissions, effluent discharge, and worker safety. Certifications such as ISO 9001 and CE marking are good indicators of quality management.
6. After-Sales Support and Spare Parts
A PGM recovery plant is a long-term investment. Choose a manufacturer that provides installation supervision, operator training, spare parts supply.
Why Source PGM Refining Plants from China?
China has become a preferred sourcing destination for precious metal refining equipment for several reasons:
Cost-effectiveness – Chinese PGM refining plants often cost 20–40% less than comparable Western systems without sacrificing core performance.
Complete supply chain – Reactors, furnaces, scrubbers, control systems, and instrumentation are all available from domestic suppliers, reducing lead times.
Engineering flexibility – Chinese manufacturers are generally willing to customize plants according to specific feedstock, capacity, and site conditions.
Turnkey project delivery – Many suppliers offer design, fabrication, installation, commissioning, and training as a single package.
Improving technology – The Chinese manufacturers now use automation, PLC control, and high-efficiency separation technologies.
Applications of PGM Recovery Refining Plants
PGM recovery refining plants supplied by Chinese manufacturers are used in a variety of industries:
- Automotive catalyst recycling companies
- E-waste and PCB recycling facilities
- Precious metal refineries and trading companies
