As with agricultural lime, dolomitic lime works to increase the pH levels of acidic soil and return the earth to nearly neutral. The primary difference between the two materials is that, in addition to containing calcium carbonate, dolomitic lime also contains a mixture of magnesium carbonate. Typically, the mineral is comprised of ...

Pre-lab discussion may set the problem up as a mining reclamation problem so that a post-lab report would address how limestone could be used to buffer the acid-drainage from tailings containing pyrite. If so, a PowerPoint will be shown of the Colorado mining regions with additional data on water quality standards for high mountain streams.

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.

2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 3–10m high, 10 4 –10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1–5kg Cum −3.

Open pit mining is used wherever feasible to minimize ore recovery costs. For instance, in the U.S.A. in 1970, open pit mines accounted for 84% of mine output (e.g., by Kennecott Copper Corporation, Salt Lake City) and only 16% was recovered from underground mining.

 · 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).
