A basic oxygen furnace (BOF) slag was used to stabilize lead (Pb) in a mine waste. Stabilization efficiencies differed depending on the slag contents (i.e., 3, 5, and 10 weight %) and the water contents (i.e., 0.05–5.0 L/kg), varying from 52.2 to 98.0%, and both the slag contents and the water contents positively affected the stabilization efficiency. X-ray photoelectron spectroscopy suggested an evidence that precipitation and adsorption mechanisms were involved. When the contribution of each mechanism was determined, the increase in the BOF slag content mainly increased adsorption mechanism probably because of the increase in the adsorption sties. The increase in the water content, on the other hand, facilitated precipitation mechanism by lowering the ionic strength. Stabilized Pb could be mobilized at redox potential of 20–85 mV due to the reductive dissolution of Fe and Mn oxides. Sequential extraction results demonstrated that the adsorbed Pb became mobilized, and the fraction of exchangeable Pb increased.

使用碱性氧气炉（BOF）炉渣来稳定矿山废料中的铅（Pb）。稳定效率因炉渣含量（即3、5和10重量％）和水含量（即0.05–5.0 L / kg）而异，从52.2％到98.0％不等，炉渣含量和水含量对稳定效率有积极影响。X射线光电子能谱表明存在沉淀和吸附机制的证据。确定每种机理的贡献后，BOF炉渣含量的增加可能主要是由于吸附强度的增加而增加了吸附机理。另一方面，水含量的增加通过降低离子强度而促进了沉淀机理。由于Fe和Mn氧化物的还原溶解，因此稳定的Pb可以在20-85 mV的氧化还原电势下动员。连续萃取结果表明，吸附的Pb得以动员，可交换Pb的比例增加。
