Environmental Hazards of Limestone Mining Sciencing

However, underground limestone mines can be found in the central and eastern United States, especially near cities. In humid climates, limestone dissolves quickly and is carried away by water. This creates caves which can become weak and collapse. Underground mining of limestone can cause a cascading environmental impact.

Limestone Treatment of Acid Mine Drainage

Neutralization ProcessChemical Properties of LimestonePhysical Properties of LimestoneLimestone SelectionLimestone Treatment SystemsLow Iron AMDLimestone Lime TreatmentConclusionsThe neutralization process provides the following benefits: 1. Removes the acidity and adds alkalinity. 2. Increases pH. 3. Removes heavy metals. The solubility of heavy metals is dependent on pH; that is, up to a point, the higher the pH, the lower the solubility, (see Figure 1). 4. Ferrous iron, which is often associated with AMD, oxidizes at a faster rate at higher pH’s (Figure 2). 5. Sulfate can be removed if sufficient calcium ion is added to ex在911metallurgist上查看更多信息
