gold refining
Extracting pure metal
Gold refining is the process of purifying raw gold to remove impurities and other metals.
The goal is to achieve high purity—typically 99.5% or higher for commercial purposes, 99.99% for investment-grade bullion.
Common methods include smelting, chemical treatment with acids, and electrolysis.
The refinery specializes in gold refining for jewelry manufacturers.
