摘要
本文研究了腐植酸溶液浸金过程的动力学行为,考察了腐植酸浓度、溶液pH值、温度等因素对浸金过程的影响.结果表明,温度和腐植酸浓度对浸金过程的影响比较大,溶液的pH值对浸金过程的影响相对较小.本文还得出了浸出速率与腐植酸浓度、溶液pH值、温度的数学关系式.
This paper makes study on the dynamics of gold leaching with humic acid solution. The effects of humic acid density, pH value of the solution and temperature on the process of gold leaching are also investigated. It is proved that the effects of humic acid density and temperature on the process of gold leaching are significant while the effect of pH value is little.In addition,the mathematic relations between leaching velocity and humic acid density or pH value or temperature are established in this paper.
