A gold jewelry refining machine is a system that uses chemical or electrolytic processes to purify scrap gold and jewelry into high-purity gold. These machines typically include components for chemical mixing, dissolution, separation, and purification, with some models designed to be compact, safe, and pollution-free enough for in-house use by jewelers. They can process various forms of scrap, such as old jewelry, dust, and polishing waste, and achieve high purity levels like 99.99%.

Key components and features

Chemical mixing and dissolution: A cylinder or tank where gold scrap is dissolved in an acid solution, such as the aqua regia method (a mixture of nitric and hydrochloric acids).
Condenser system: A system that cools and recovers some of the acid, and neutralizes fumes to reduce pollution.
Scrubber unit: A component to further clean waste gas, with some approved by standards like PH7.
Filtration and separation: Machinery like a filter press or a decanter centrifuge is used to separate the gold-bearing solution from other materials.
Precipitation: Chemicals are added to the solution to precipitate the gold as a powder or sludge.
Filtration and rinsing: The gold powder is then filtered and rinsed to remove residual chemicals.
Melting and casting: An induction furnace may be used to melt the purified gold powder and cast it into bars.
Automation and safety: Modern machines often have features like acid auto-filling, single-user operation, low maintenance, and safety features to make the process safer and more user-friendly.

How it works (Simplified process)

Preparation: Scrap gold jewelry is analyzed and prepared for the process.
Dissolution: The gold is dissolved in an acid solution, often aqua regia, which separates it from other metals.
Neutralization and separation: Fumes are neutralized, and the solution is processed to separate the dissolved gold.
Precipitation: The gold is precipitated out of the solution as a solid.
Filtering and washing: The precipitated gold is filtered and washed to remove impurities.
Purification and recasting: The pure gold is then melted and recast into new forms.
