GOLD REFINING
GOLD REFINING
1. SMELTING
Smelting is the process of extracting gold from raw ore or impure gold by applying intense heat. At Crystal Core Gold Refinery, we use high-temperature induction furnaces to melt the material, separating impurities from the precious metal. During this process, flux compounds such as borax and silica are added to bind with unwanted elements, allowing pure gold to separate and settle at the bottom. Once cooled, the refined gold is cast into bars or nuggets, ready for further purification or trade.
2. X-Ray Fluorescence (XRF) Analysis
XRF is a non-destructive testing method that determines the exact composition of gold and other metals in a sample. Using high-energy X-ray beams, we excite the atoms in the gold, causing them to emit fluorescent X-rays unique to their element. Our advanced XRF spectrometers analyze these emissions in real-time, providing instant and highly accurate purity readings without altering the sample. This method ensures fast, precise, and reliable gold assessment for both small and large quantities.
3. Acid Testing (Touchstone Method)
Acid testing is a traditional yet effective method for verifying gold purity by measuring its reaction to different acids. At Crystal Core Gold Refinery, we use a touchstone to rub a small portion of the gold, leaving a streak on the surface. We then apply nitric acid and aqua regia (a mix of nitric and hydrochloric acid) to observe the reaction. Based on how the metal dissolves or resists the acids, we can determine the karat grade and authenticity of the gold. This method is useful for quick and cost-effective gold verification before deeper analysis.
