Silver Electrolysis Refining Machines

Automatic Silver Electrolysis Refining Machine 10kg Per 24 Hours

Workshop scale silver cell for 80-90% silver bars and old jewelry

  • FunctionRefining silver of 80% to 90% purity to 99.9% or 99.99%
  • Capacity10kg/24 hours
  • Anode80-90% purity silver in four titanium baskets
  • CathodeTitanium cylinder
  • Electrolyte10% nitric acid solution
Product Overview

What This Machine Does

This machine refines 80% silver bars or old 90% silver jewelry to 99.9% or 99.99% silver at 10kg per 24 hours.

Silver dissolves from the titanium baskets into dilute nitric acid and redeposits on the titanium cylinder cathode as 99.99% metal.

Gold and copper in the feed separate into the anode mud during the same run.

Key Benefits

What You Get

  • 99.99% metallic silver obtained quickly without a full industrial electrolysis house.
  • Nitric acid consumption and emission are both reduced against the traditional method.
  • Anode mud carries gold and copper for separate recovery.
  • Zero liquid leakage housing keeps precious metal losses and environmental exposure down.
Who It Is For

Who Buys It

  • Jewelry manufacturers with a steady flow of silver scrap
  • Regional refiners serving local jewellers and pawn shops
  • Silverware and tableware factories recycling process scrap
  • E-waste operations upgrading recovered silver slag
Problems It Solves

What It Fixes

  • A 3kg cell becomes the bottleneck once scrap volume grows past a few kilos a day.
  • Traditional acid refining releases nitric fume and eats reagent.
  • Outsourced refining costs a fee on every kilo and returns metal days later.
  • Impure silver cannot be sold into bullion or electronics markets.
Technical Features

How It Is Built

  • Four round titanium baskets as the anode holder
  • Rotating titanium cylinder where refined silver deposits
  • 10% dilute nitric acid electrolyte
  • Anti-corrosion PLC control panel
  • Zero liquid leakage machine housing produced by a special welding method
  • Full anti-corrosion construction for long service life

Use Guide

Running The Machine

  1. Step

    Check that every screw is tight, that the titanium basket bag is undamaged, and that the inlet and outlet valves are closed.

  2. Step

    Prepare a 10% dilute nitric acid electrolyte.

  3. Step

    Distribute the silver nuggets evenly across the four titanium baskets and pour in the acid until the charge is covered.

  4. Step

    Switch on the power and set the adjustable voltage CV between 1.6V and 4V; the current follows and needs no separate adjustment.

  5. Step

    Start the electrolytic stirring switch.

  6. Step

    Replace the electrolyte based on feed purity: once per refining for impure silver, several reuses for clean high grade silver.

FAQ

Questions About The Silver Electrolysis Refining Machine 10kg Per 24h

How does this differ from the 3kg machine?

Same working principle and construction at a higher daily throughput. The adjustable voltage range on this model is 1.6V-4V rather than 5V-8V.

Can it refine 925 sterling silver?

It is specified for 80-90% purity silver bars and old silver jewelry. Send your feed assay with the enquiry so the right model is quoted.

What do I do with the anode mud?

It contains gold and copper separated during refining and is processed separately to recover them.

How pure is the silver on the cathode?

99.9% or 99.99% metallic silver.

Does the machine leak?

The housing is welded by a special method for zero liquid leakage, which minimises precious metal loss and environmental contamination.

What maintenance does it need?

The machine is simple to operate and maintain, with a full anti-corrosion design for long service life.
