Slags are transported along with slag tailings to "slag dumps", where they are exposed to weathering, with the possibility of leaching of toxic elements and hyperalkaline runoffs into the soil and water, endangering the local ecological communities. Leaching concerns are typically around non-ferrous or base metal slags, which tend to have ...

A long string of ladle cars dump their molten cargo at West Mifflin's Brown's Dump. Slag is a waste by-product of the smelting process of making steel. When rock containing iron ore is smelted in a furnace, the impurities separate from the iron and become a molten rock called slag.

2022年2月3日 · The present study assessed and estimated the impact of slag dump piling up for the last 60 years on the hydrogeological environment in the industrial city of Durgapur in eastern India. Groundwater survey resembles the unconfined nature of shallow aquifer with elevated concentrations of Ca and Mn in the study area.

采用聚丙烯酰胺（PAM）为土壤结构调理剂，以生物炭、河道底泥为养分改良剂，以滇中引水工程弃渣场退化土壤为修复对象，设置空白对照CK和T1（PAM）、T2（PAM+生物炭）、T3（PAM+河道底泥）、T4（PAM+生物炭+河道底泥）4种处理，考察复配材料施加对土壤理化性质、植物（狗牙根）生长及土壤细菌群落结构的影响。 结果显示，4种处理均能显著提高土壤电导率、养分含量、土壤平均重量直径（MWD）以及≥0.25 mm团聚体（WR 0.25）的含量，同时 …

2015年6月1日 · Summarize mineralogy and geochemistry of ferrous and non-ferrous slags. Discuss potential environmental issues related to weathering of slag dumps. Outline construction, secondary metal recovery, and environmental applications. Compiled results from over 150 published studies on slag and included own data.

研究表明:溃决运动共持续300s,溃决运动主要沿沟道主沟滑动,主滑方向的平均厚度约2.94m,最大泛滥距离约270m,溃后龙头处距离两处村落分别为231m和379m;监测点处速度显示,溃决运动速度具有突然增加,然后逐渐减少的趋势,整个溃决运动分为启动加速、稳定蠕滑和减速堆积3个阶段;溃后危险性分区表明,低、中、高风险区占比分别为49.32%、25.64%、25.64%,对居民区无明显影响。 研究成果可分析弃渣场溃决运动路径、泛滥范围及运动速度特征等,对降低弃渣场溃决风险和应急 …

2020年2月3日 · Other artificial mountains are formed from slag, the molten rock separated from iron ore during steel production. Slag is dumped in a waste pile, which hardens into concrete-like rock when...

2021年11月1日 · We also present SIP results from field measurements at a historical slag dump where most of the slag samples reveal high amounts of iron, zinc, silica, and barium. Our results reveal a discrimination between three different slag grades (low, medium, high) by using the imaginary conductivity σ″ at a medium frequency (1–10 Hz) in both ...

The present study assessed and estimated the impact of slag dump piling up for the last 60 years on the hydrogeological environment in the industrial city of Durgapur in eastern India. Groundwater survey

弃渣场是工业固体废弃物的集中处理和储存区域，其稳定性对环境和人类健康具有重要影响。 本文旨在介绍弃渣场稳定性监测的重要性，并探讨其在环境保护、人类安全和可持续发展等方面的应用前景。 通过综合利用现代监测技术和数据处理方法，能够实时监测弃渣场的变化情况，预测和预防潜在的灾害风险，为弃渣场管理和决策提供科学依据。 Three-dimensional Stability Monitoring Of Slag Dump And a Review Study On Its Application. Tang Enhai12, Sun Hao3，Li Hao4.
