英文摘要：

Using the solubility method, the solubility of CuCl2 in liquid-undersaturated HCl-bearing water vapor was investigated experimentally at temperatures of 330-370℃ and pressures of 4.2-10 MPa. The resuits have shown that hydration could significantly enhance copper solubility and the concentrations of copper were positively correlated with PH2O. The solubility of copper in vapor phase increased with increasing PH2O at the constant temperature. CuCl2 was transported as hydrated species CuCl2（H2O）n^gas in water vapor. The formation of complexes is proposed to be the result of the following reaction： CuCl=^solld ＋ nH2O^gas = CuCl2 （H=O）n^gas The hydration number n decreased slightly with increasing temperature. Statistical hydration numbers are 4.0, 3.6 and 3.3 at 330, 350 and 370℃, respectively.
