The Study on Leach Test of Au, Pd in Ore-Bearing Hydrothermal System,Tuanjiegou Gold Deposit

摘要

The study indicates that geochemical features of Au, Pd in the ore-bea ring hydrothermal system. Au is active and Pd is distinctly inert. Both tend to solute in alkaline media (P=100×10 5Pa,T=200℃). The condition of P=100×10 5 Pa,T= 100℃ is favourable to the solution and rembilization of Au. The best physical a nd chemical environment of gold mineralization is P=20×10 5～30×10 5Pa,T=250 ℃,pH≈7.56.
