2021-5-5 · Limestone Mine. Limestone is a sedimentary rock, made up mostly of the mineral calcite, a form of calcium carbonate, CaCO 3. The calcium carbonate is originally produced by living animals (such as shellfish). Later, much of it goes into solution in sea water, and then is deposited as limestone. Calcium carbonate gets precipitated when the physical

Characterization of limestone reacted with acid-mine

Limestone was characterized before and after treatment with constant flow and with the new pulsed limestone bed process using AMD from an inactive coal mine in Pennsylvania (pH=2.9, Fe =150 mg/l, acidity =1000 mg/l CaCO 3). In constant flow experiments, limestone is completely armored with reddish-colored ochre within 48 h of contact in a fluidized bed reactor.

Characterization of limestone reacted with acid-mine

2003-11-1 · Abstract. Armoring of limestone is a common cause of failure in limestone-based acid-mine drainage (AMD) treatment systems. Limestone is the least expensive material available for acid neutralization, but is not typically recommended for highly acidic, Fe-rich waters due to armoring with Fe (III) oxyhydroxide coatings.
