Purpose-built refinery for gold and silver is the single most important investment you can make to transform scrap, doré, or electronic waste into market-ready bullion. At Guanma Machinery, we engineer complete precious metal recovery lines 99.99% purity, lower operational costs.
Why a Professional Refinery for Gold and Silver Is Non‑Negotiable
A dedicated refinery gold silver brings four critical advantages:
Maximum precious metal recovery
Modern systems recapture even trace particles from polishing sweeps, anode slimes, and complelx scrap, achieving recovery rates exceeding 99.5%.
Guaranteed high purity
Automated electrolytic or chemical refining consistently delivers 99.99% (four nines) gold and silver, meeting LBMA and COMEX specifications.
Environmental and regulatory compliance
Closed-loop scrubber systems, zero liquid discharge, and sealed reactors keep your workplace safe and aligned with ISO 14001 and local emission laws.
Operational cost control
Precisely engineered burners, rectifiers, and reaction vessels slash acid consumption, power usage, and manual labor hours compared to improvised setups.
Core Technologies Powering a Gold and Silver Refinery
The right technology depends on your feedstock, throughput goals, and desired final form—be it granules, bars, or powder. The most widely deployed systems include:
Electrolytic Silver Refining System
When your target is fine silver suited for industrial contacts, sterling silverware, or investment bars, an electrolytic silver refinery delivers unmatched precision. Our cells use high‑density graphite or titanium cathodes and carefully formulated silver nitrate electrolytes to deposit 99.99% silver crystals.
Small‑Scale and Containerized Refinery Units
Many start‑up miners and urban recyclers are actively searching for a “small scale gold refinery” or “modular silver refining equipment.” Recognizing this demand, we offer compact, pre‑commissioned refinery for gold silver units housed in 20‑foot or 40‑foot shipping containers.
How Guanma Machinery’s Refinery Equipment Solves Real‑World Problems
Feedstock Complexity
Do you handle a mix of cyanide‑leached sponge gold, dental scrap, and old silver contacts? Our refinery systems are designed with interchangeable reaction vessels and multiple filtration circuits so you can switch feedstock profiles.
Fume Management
Guanma Machinery gold and silver refinery includes a staged wet scrubber and activated carbon adsorption tower, capturing NOx, SO₂, and chlorine long before they escape into the workshop.
Water and Waste Treatment
Our compact integrated skids neutralize acidic rinses, precipitate heavy metals, and recycle rinse water—dramatically cutting your waste handling bill.
Training and Support
We offer on‑site commissioning with one‑on‑one operator training, detailed troubleshooting videos, and 24/7 remote support, ensuring you get full value from your refinery for gold and silver from day one.
Key Applications Across Industries
Jewelry Manufacturing & Pawnbroking Chains
Turn production scrap, polishing dust, and customer trade‑ins into fine gold shot and investment‑grade silver granules ready for new designs.
E‑Waste & Catalytic Converter Recyclers
Guanma’s optional pyrolysis pre‑treatment module and electrochemical recovery line form a dedicated precious metal refinery that handles e‑scrap safely while maximizing silver and palladium yields.
Dental Labs & Hospitals
Dental alloys, crowns, and amalgam traps contain significant gold, silver, and platinum group metals.
How to Select the Right Refinery for Gold and Silver
Throughput
From 5 kg bench‑top batch units to 500 kg continuous lines, matching capacity to actual volume avoids bottlenecking and unnecessary capital expenditure.
Feedstock Types
Share a sample composition with our application engineers for an honest suitability assessment.
Final Purity and Required
Gold can be produced as granules for alloying, cast into 1 kg bars, or precipitated as a high‑surface‑area powder.
Environmental Standard
We can pre‑configure your refinery for gold and silver with emission monitoring ports and certified waste‑handling attachments to meet the strictest regulations in North America, Europe, the Middle East, and Africa.
