Nov 22, 2007· Traditionally acid mine water is neutralised with lime. Limestone is a cheaper alternative for such applications. A case study showed that limestone can be used effectively to replace lime for the neutralization of arsenic rich acid water. The cost of limestone treatment is 45.8% less than that of lime. The acidity can be removed from 33.5 to 0.06 g/L (as CaCO3).

Milled limestone is used in underground coal mining to prevent and suppress coal dust explosions. It is typically sprayed on mine walls, where it acts as a coal dust binder, preventing the dust from becoming airborne and contributing to the risk of explosion. In addition, bags of limestone are stored at strategic locations in the mine.
