Method for Extracting Gold from Gold Tailings

     

Method for Extracting Gold from Gold Tailings:

1、Creating Slurry: Mix gold tailings with water to form slurry.

2、Fine Processing: Process the slurry through fine processing to reduce particle size below 2 micrometers. Additionally, a chemical agent containing a ligand capable of forming complexes with gold ions is added either during or prior to the fine processing. After fine processing, the chemical agent is thoroughly reacted with the slurry.

3、Solid-Liquid Separation: Perform solid-liquid separation to isolate the liquid phase, which contains gold complex ions.

This method operates under mild conditions and has low production costs. It consumes less reagent, achieves high extraction speed, and a recovery rate of up to 98%. Post-extraction, the solid residue can be utilized for manufacturing ceramic tiles, concrete additives, lightweight void fillers, or dried as filling material for rubber or plastic. This process effectively converts waste into valuable resources through maximum resource utilization.
