Large charges reduce whole areas of limestone to rubble, which is removed for use as crushed stone. The noise, dust, and impact from explosions can result in noise pollution and dust.
A limestone with a high CaCO3 content and with low magnesium and other impurities is best suited for treating AMD. The choice of a limestone should be based on the chemical composition, cost, and a laboratory test between the actual limestone and acid mine drainage.
