Limestone is a basic type of ore which is abundant in the world. It is primarily used to produce Concrete, an essential material in factory construction. Limestone can be harvested by hand (default E) in trace amounts from resource deposits scattered across the world, or from inexhaustible resource nodes on which Miners can be constructed to extract automatically.
Learn More· Over 90% of the mining activities in developed countries adopt open pit methods . In large open pits, the orebody is usually found relatively close to the surface (thus ensuring overburden–to–ore ratios suitable for profitable mining operations) in sub-horizontal or slightly inclined deposits.

Learn More· 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.
Learn MoreInteresting Facts – Limestone. Limestone is a sedimentary rock composed mainly of the mineral calcite, which is a crystalline form of Calcium Carbonate (CaCO3). Limestone often contains variable amounts of silica in the form of Jasper or Flint, as well as amounts of clay, silt, and sand as disseminations, nodules, or layers within the rock unit.
