The rigorous technical flow of alluvial gold extraction & 24K refining
Modern mechanized mining engineered to isolate gold with minimal environmental disturbance — followed by a five-stage industrial refining process to 99.99% purity.
Mechanized alluvial extraction
Our field operation follows a strict industrial sequence — from prospecting and delineation to excavation, washing-plant supply, mat retention and vibrating-table concentration that isolates raw gold dust.
- Prospecting & structural delineation
- Mechanical excavation of alluvial gravel beds
- Industrial washing trommels
- High-retention mat capture
- Vibrating-table concentration
From raw ore to 99.99% purity — in five stages
Carating & Mass Spectrometry
Electronic balances, mass spectrometry and Archimedean density measure alloys and calculate exact acid quantities.
Centrifugation & Granulation
Pre-melted gold is spun into fine grain granules, expanding surface area for efficient reaction.
Aqua-Regia Reaction
Sealed reactions with exact hydrochloric and nitric ratios dissolve base metals, isolating pure gold.
Thermal Smelting
Gold crystals cast into premium mirror-finish bars in an E-Mark 2023 furnace.
Stamping & Certification
Bars verified, stamped with individual serial codes and given official structural certificates.
