摘要
本研究针对某冶炼厂的有色冶炼废渣,利用生物浸出技术浸提废渣中的有价金属,考察浸出前后各重金属形态变化,实验结果表明:浸出后余渣中Cd、Mn、Cu、Pb、Zn等有害元素含量显著降低,浸出过程重金属的酸可提取态相对含量逐渐降低,残渣态相对含量逐渐提高。
In this paper, bioleaching technology was used to extract valuable metals from smelting slag from a nonferrous smelter. The changes of heavy metal forms before and after the bioleaching were investigated. Results show that toxic clement contents such as Cd, Mn, Cu, Pb, Zn in the residues decrease significantly after the bioleaching and acid extractable relative content decreases gradually during the bioleaching process, meanwhile, residual form relative content rises gradually.
