3 Reasons to mine or quarry a resource: On a piece of paper, write your name and list five things, other than energy, for which materials are mined. On a piece of paper, write your name and list five things, other than energy, for which materials are mined.

4 Some materials which are mined or quarried: Limestone is produced from the mineral calcite (calcium carbonate) and sediment. The main source of limestone is the limy ooze formed in the ocean. The calcium carbonate can be precipitated from ocean water or it can be formed from sea creatures that secrete lime such as algae and coral.

Chalk is another type of limestone that is made up of very small single-celled organisms. Chalk is usually white or gray in color.

If you drop vinegar on limestone it will fizz. Put a limestone rock into a plastic jar and cover it with vinegar. Cover the jar and watch the bubbling of the calcium carbonate and also the disintegration of the rock over a few days. Limestone can easily be dissolved by acids.

5 Limestone Limestone is of rather low value, but nevertheless it is probably the most important mineral. It is mined and used in large amounts, which often conflicts with the protection of karst areas and caves.

Later, after he become resident he used the rock for building purposes. Various kinds of limestone and marble were used for walls, pillars and much more. The soft rock was used to produce sculptures. Even limestone roofs and floors were built. In history man used first the flint nodules, which are common in limestone. Later, after he become resident he used the rock for building purposes.

With the increase of technology many more usages of lime were found. It is burnt in kilns to produce lime, white color and finally cement. It is needed to produce glass, porcelain, or as addition in the melting of many metals. It is used to purify coal and the waste gas of power plants using carbon based fuel. Limestone neutralizes many toxic substances, especially sulfur oxide and sulfur dioxide. In combination with sulfur it is converted into gypsum.

Limestone is typically quarried, as it occurs in huge sedimentary layers, and as mining is to expensive.

6 What has limestone been used for? Most notably, limestone was quarried to build the Great Pyramids at Giza. Most notably, limestone was quarried to build the Great Pyramids at Giza.

7 Gold and other precious metals Gold is the most malleable and ductile metal; a single gram can be beaten into a sheet of one square meter, or an ounce into 300 square feet. Gold leaf can be beaten thin enough to become translucent. The transmitted light appears greenish blue, because gold strongly reflects yellow and red.

14 Tungsten Tungsten (W) is a metal with a wide range of uses, the largest of which is as tungsten carbide in cemented carbides. Cemented carbides (also called hardmetals) are wear-resistant materials used by the metalworking, mining, and construction industries. Tungsten metal wires, electrodes, and/or contacts are used in lighting, electronic, electrical, heating, and welding applications. Tungsten is also used to make heavy metal alloys for armaments, heat sinks, and high-density applications, such as weights and counterweights; super alloys for turbine blades; tool steels; and wear-resistant alloy parts and coatings. Tungsten composites are used as a substitute for lead in bullets and shot. Tungsten (W) is a metal with a wide range of uses, the largest of which is as tungsten carbide in cemented carbides.
