黄铁矿表面和方铅矿表面对金的硫氢络合物的吸附特点不同,前者更易于将表面络合态金Au(I)还原成单质金Au(O),且吸附能力也强一些。经重结晶实验以后,天然黄铁矿和合成黄铁矿表面的吸附金均发生了明显的迁移、归并作用,但二者归并的程度不同。方铝矿表面的吸附金则归并效果不明显。结合矿物表面特征,利用矿物表面缺陷模型和表面扩散模型对上述结果进行了解释,并与矿石金的赋存状态进行了对比。
The adsorption characteristics of the sulfur-hydrogen complexes on the pyrite surface and the galena surface are different. The former is more likely to reduce the surface complexation gold Au (I) to the elemental gold Au (O) and the adsorption capacity is also stronger . After the recrystallization experiment, the adsorption of gold on the surfaces of natural pyrite and synthetic pyrite evidently migrated and merged, but the degree of merger was different. On the surface of the side of the adsorption of gold is combined effect is not obvious. According to the mineral surface features, the above results are explained by the mineral surface defect model and the surface diffusion model, and compared with the occurrence status of ore gold.
