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。
本研究針對某冶煉廠的有色冶煉廢渣，利用生物浸齣技術浸提廢渣中的有價金屬，攷察浸齣前後各重金屬形態變化，實驗結果錶明：浸齣後餘渣中Cd、Mn、Cu、Pb、Zn等有害元素含量顯著降低，浸齣過程重金屬的痠可提取態相對含量逐漸降低，殘渣態相對含量逐漸提高。
본연구침대모야련엄적유색야련폐사，이용생물침출기술침제폐사중적유개금속，고찰침출전후각중금속형태변화，실험결과표명：침출후여사중Cd、Mn、Cu、Pb、Zn등유해원소함량현저강저，침출과정중금속적산가제취태상대함량축점강저，잔사태상대함량축점제고。
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.
