【摘要】Experiments on water-rock interaction were carried out on wall-rock samples from the Mobin gold deposit, Southwest Hunan, China, with the aim of determining the optimum physical and chemical conditions for the mobilization of gold in solution. Results indicate that gold is most easily mobilized from the wall rock-tuffaceous slate of the Mobin Deposit. Mobi lization is optimized if fluids are neutral to slightly alkaline and contain both chlorine and sulphur ions at the concentration and composition of about [0.25M (NH4)2S + 1M NaCl]. The amount of gold leached from the tuffaceous slate increases with temperature although the effect decreases above about 200℃ . 【总页数】8页(258-265)
