| 摘 要： | 金矿物在表生条件下溶解为离子金.离子金与表生络合剂结合成金络离子团迁移.在物化条件改变时,由于有机炭、粘土矿物及带异性电荷胶体吸附,使金络离子团分解成原子金沉淀.

| Abstract: | Ionic gold is obtained from the solution of gold minerals under the condition of oxidation. Then the gold ions formed with an oxidic complexing agent begin to transfer.When the physical and chemical condition changes, organic carbon and clay mineral are adsorbed by the colloid with charges of diffcrent polarity. This causes decomposition of the gold complex ions and precipitation of the atomic gold. Thc paper also dcals with the procedure of the growth of gold particles. |
