Acid peroxide gold recovery is a gold extraction process that involves using a combination of hydrochloric acid (HCl) and hydrogen peroxide (H2O2) to dissolve gold from electronics or other gold-bearing materials. The process involves several steps:

1. Collect and prepare the gold-bearing material: 

This can include electronics, computer parts, or other items that contain gold.

2. Crush the material: 

The material is crushed into small pieces to increase the surface area for the acid peroxide solution to dissolve the gold.

3. Mix the acid peroxide solution: 

A solution is prepared by mixing hydrochloric acid and hydrogen peroxide in a specific ratio, typically 3 parts HCl to 1 part H2O2.

4. Add the acid peroxide solution to the material: 

The acid peroxide solution is added to the crushed material and allowed to react for several hours.

5. Filter and rinse the material:

 The material is filtered to separate the gold solution from the remaining material. The gold solution is then rinsed several times to remove any remaining acid.

6. Precipitate the gold:

 The gold is precipitated from the solution using a reducing agent, such as sodium metabisulfite, which causes the gold to form solid particles that can be filtered and washed.

The acid peroxide gold recovery process can be effective for recovering gold from electronics and other materials, but it does require the use of strong acids and can be hazardous if proper safety precautions are not taken. It's important to follow proper safety protocols and dispose of the waste materials in accordance with local regulations.
