Sedimentary rock - Carbonate rocks: limestones .

Carbonate rocks: limestones and dolomites. Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO 3).Dolomites are mainly produced by the secondary alteration or replacement of limestones; i.e., the mineral dolomite [CaMg(CO 3) 2 ...

Limestone: The Calcium Carbonate Chemical .

Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it a truly versatile commodity. Portland cement is ...

Mining - Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Limestone is a very common type of sedimentary .

Limestone is a very common type of sedimentary rock. Rocks come in three types: igneous, metamorphic and sedimentary. Sedentary rock forms from deposits of small particles and other debris, usually from the Earth's surface or bodies of water. Limestone can be formed in two ways: biologically or chemically. The most common way is biologically, meaning it is made from living organisms. Sea ...

Deposition of Ores in Limestone

A study should be made of the structure of the ore-bearing limestones, with the special object of determining the causes that have made certain strata favorable for ore, while other beds in the same geological formation, having an almost identical chemical composition, and so situated that they are traversed by the same fissures, through which the mineral-depositing waters have been introduced ...
