摘要:

为了促进我国自主研发的环保提金药剂完全替代剧毒NaCN用于黄金冶炼,解决氰化法提金过程中含氰废水、废渣污染环境的问题,研究了某环保药剂对不同金矿类型的适应性以及活性炭对环保药剂贵液中金吸附的选择性。研究结果表明,环保药剂对焙砂酸浸渣、高硫金矿中金的浸出效果与氰化法相当,对硫化金矿的浸出速度比氰化法快,浸出过程环保药剂用量与矿物类型有关。活性炭对环保药剂浸出贵液中金和银的吸附具有选择性,贵液pH值保持在10.0~10.5时吸附效果更好。由于环保药剂成分分析方法不健全,无法揭示浸出过程环保药剂的消耗量与矿物类型的关系,且无法检测吸附前后药剂的浓度及其成分变化。因此,在研究药剂分析方法的基础上,揭示环保药剂溶金机理和环保药剂体系与矿物的相互作用是当前研究的主要任务。

Abstract:

In order to make an environmental agents completely replacing highly toxic sodium cyanide for gold smelting and solve the problem of the environmental pollution of cyanide waste water and waste residue during the process of extracting gold with cyanide,the adaptability of an environmental agent to different gold types and the adsorption selectivity of activated carbon to gold in the liquid of the environmental agent have been studied.The results show that the effect of the environmental agent on leaching gold from acid leaching residue and high sulphur gold ore is equivalent to that of cyanide,and the leaching rate of vulcanization gold ore is faster than the cyanide,and the amount of environmental agent and mineral type are related to the leaching process.The adsorption of gold and silver in the leaching precious liquid of environmental agent by activated carbon is selective,the pH value of the liquid should be kept at 10.0 to 10.5 to get better adsorption results.Due to the analysis method is not perfect,it is impossible to reveal the relationship between the consumption of agent during leaching process and the mineral types,and the change of concentration and composition before and after the adsorption of activated carbon can not be detected.Based on the study of pharmaceutical analysis method,the main task of current research is to reveal the gold dissolution mechanism of environmental agents and the interaction between the environmental protection agents and minerals.

Key words:  cyanide pollution, environmental agent, adaptability, activated carbon, adsorption selectivity, analysis method, gold dissolution mechanism
