Gold Mining Process in China (Simplified Diagram)
# 1. Exploration & Prospecting
– Geological Surveys: Satellite imaging, geochemical sampling, and drilling to locate gold deposits.
– Reserve Estimation: Confirming economically viable gold reserves (e.g., Shandong, Henan, Xinjiang).
# 2. Mining Methods
China uses both:
– Open-Pit Mining (for near-surface deposits)
– Underground Mining (for deeper veins)
# 3. Ore Processing
– Crushing & Grinding: Ore is broken into smaller pieces.
– Gravity Separation: Initial gold recovery using density differences.
– Flotation & Cyanidation: Chemical leaching (cyanide or non-toxic alternatives) extracts gold from ore.
# 4. Refining & Smelting
– Gold concentrate is smelted into doré bars (~90% purity).
– Further refined to 99.99% purity (e.g., at China National Gold Group refineries).
# 5. Distribution & Export
– Gold is sold to banks (People’s Bank of China), jewelry makers, or exported.

Challenges in Chinese Gold Mining
✔️ Environmental Regulations: Stricter controls on cyanide use and land reclamation.
✔️ Energy Costs: High electricity demand for processing.
✔️ Labor Safety: Improving conditions in small-scale mines.
