LIMESTONE MINING Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.
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 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, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.
Background. South Africa faces several problems with ensuring that its water resources are clean and plentiful enough for use. For example, there is a growing problem of toxicity of South Africa''s water resources due to increased bacterial growth, including Escherichia coli, Aeromonas, Pseudomonas, Salmonella, Shigella and Vibrio spp [1].
Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic
Experiments with ten groups of limestone specimens (four samples per group) under ten specific temperatures, 25 °C, 100 °C, 200 °C, 300 °C, 400 °C, 500 °C, 600 °C, 700 °C, 800 °C, and 900 °C, show that the hightemperature effect on the elastic modulus of rocks conforms to thermoelastic responses with a quadratic temperature function.
