What is Gold Refining. Gold refining is the process of purifying raw gold to remove impurities and separate it from other metals or materials. The goal is to produce high-purity gold, often reaching 99.9% or higher. Refining can be done using various methods, depending on the composition of the raw material and the desired purity level.

1. Dip Samples are Taken from Molten Gold; Refining gold begins with melting the gold in a crucible and taking dip samples to test the millesimal fineness of the gold. This provides measurable purity to benchmark against in the final stages of refinement. 2. Chlorination Separates Impurities from Gold; The Miller process is fast and simple.
