Transforming raw ore into a certified 99.99% pure bar is a precise, five-stage industrial process.
Stage 1 — Carating & spectrometry
Raw gold undergoes initial testing via electronic balances, mass spectrometry and Archimedean density to measure alloys and calculate acid quantities.
Stage 2 — Centrifugation & granulation
Pre-melted gold is spun into fine granules, expanding surface area for efficient chemical reaction.
Stage 3 — Aqua-regia separation
Granules react inside sealed units using exact ratios of hydrochloric and nitric acids, dissolving base metals and isolating pure gold.
Stage 4 — 1600°C thermal smelting
Isolated gold crystals are cast into premium mirror-finish bars in an E-Mark 2023 furnace.
Stage 5 — Stamping & certification
Finished bars are verified, stamped with tracking serial codes and issued official certificates.
