摘要
研究了红土镍矿冶炼废渣-镍铁渣的腐蚀性、浸出毒性、热稳定性、水环境化学稳定性、放射性等环境安全性能,研究结果表明,镍铁渣腐蚀性、浸出毒性、放射性小于国家标准限值,在自然环境中镍铁渣自身体系遇热稳定,在地下水、雨水、酸雨等自然水环境中其所含主要金属镍、铜、铁、钴、铅、铬、镁、钙等化学性质稳定。
The properties of environmental safety about Ferro - Nickel slag are researched, including corrosivity, extraction toxicity （ ET ）, thermal stability, and radioactivity. Corrosive, radioactive and ET are less than the limited value of national standard; The properties of Ferro - Nickel is stable when it is heated Less than 600 degrees Celsius ; The elements of Ferro - Nickel slag is little leached when it is immersed by groundwater, rainwater, acid rain and other natural water.
