Bacterial and chemical oxidation of gold-bearing pyrite gives rise to not only ferric sulfate and sulfuric acid but also ferrous sulphate and low-valence oxide of sulfur. The potential in the system is too low to dissolve native gold to form Au(SO4)2- Experiments indicate that gold does not dissolve in sulfatic iron solution.

含金黄铁矿在细菌氧化、化学氧化过程中，除生成高铁的硫酸盐和硫酸外，还生成了亚铁的硫酸盐及硫的低价氧化物，体系中的电位较低，距溶解自然金呈Au(SO_4)_2~-所需电位甚远，实验表明，金不溶于硫酸铁溶液中。
