Spent Low Aurum Content Solution Discharge Reduction and Resource Recovery Equipment

1 High return on investment. 2 Exchange resin is reusable which reduces operating cost. 3. Simple installation and easy operat

1. Technical Introduction

It is a technique which adopts ‘ion exchange’  to recovery aurum from spent solution for plating bath wash in au-plated line, immersion gold line and gold finger line in PCB or electro-plating plants. It includes tail water (Au≤4~8ppm) which adopts electro-deposit technique to recovery gold and which adopts active carbon absorption to recovery gold. 

2. Application Scope

It’s applied to integrated spent aurum containing solution in PCB industry, electro-plating industry, smelting industry, painting or jewelry making industry.

3. Equipment Introduction 

3.1 Work Flow

Spent aurum containing solution firstly is pumped through filter to remove particle solids and suspended solids.  And then gold is absorbed from water in ion exchange tower with resins which adopts 3-level absorption treatment. Aurum-adsorbed resin then be replaced by new ones when it is fully loaded and aurum is finally be recovered through resin analysis treatment.

4. Environmental-protection Standards

4.1 Exhaust gas emission reaches National Environmental Protection Standards: exhaust gas is discharged after treatment, no odor.

4.2 Resin can be reused, no pollution to environment.

4.3 Wastewater is treated by wastewater treatment station before discharge.

5. Features and Advantages

5.1 High return on investment.

5.2 Exchange resin is reusable which reduces operating cost.

5.3 Simple installation and easy operation.

5.4 Less floor space. It can be installed while prior production line is still running.

5.5 Recovered metallic material can be directly smelted. It can used to recycle other precious metals.
