Process Overview

The Gold Refinery Project introduces a novel methodology to refine gold, focusing on processing dore bars and scraps. The refinery employs innovative chemical and electrolytic techniques to achieve exceptional purity levels. Advanced refining technologies ensure efficient processing, overseen by experienced metallurgists and chemists to maintain stringent quality control. Sustainability is paramount, with waste reduction and ethical sourcing practices integral to operations.

Collection of Raw Material

Gold-containing materials such as gold ore, scrap jewelry, electronic components, or gold bars are collected and sorted for processing

Assaying

The raw material undergoes assaying to determine its gold content using fire assay or instrumental methods such as X-ray fluorescence (XRF) or atomic absorption spectroscopy (AAS).

Melting

Raw material is melted in a furnace at temperatures exceeding the melting point of gold (1064°C or 1947°F) to form a homogeneous liquid.

Chemical Treatment (Refining)

The molten gold is treated with various chemicals to remove impurities: ⬧ Aqua regia (a mixture of hydrochloric acid and nitric acid) is commonly used to dissolve base metals and silver, leaving behind gold.

Chemical Treatment (Refining)

Alternatively, other chemical processes like the Miller process or the Wohlwill process can be employed for refining, each with specific advantages and limitations.

Electrolysis

After chemical treatment, the gold solution undergoes electrolysis for further purification: ⬧ Electrolytic cells contain a gold anode and a cathode made of stainless steel or other inert materials.

Electrolysis

The gold ions migrate from the anode to the cathode, depositing pure gold onto the cathode. ⬧ This process ensures the highest purity of gold, typically 999.9 (24K).

Filtering

The refined gold solution is filtered to remove any solid impurities or undissolved particles, ensuring a clean final product

Casting

The purified gold is then cast into molds to form gold bars or other desired shapes. ⬧ Casting machines are used for this process, which may include vacuum casting or centrifugal casting machines.

Casting

Molds can be made of graphite, steel, or other materials suitable for handling molten gold. ⬧ Quality control checks are conducted on the refined gold to verify its purity and compliance with standards. This may include assaying the final product to confirm its 999.9 purity.
