The lateral cutting is usually done by running a wire around an exposed block, and the wire is driven like an endless belt. An abrasive and water provide the cutting action and cooling.
The vertical cutting may be done by drilling a series of holes, then splitting it hydraulically or mechanically.
After quarrying into large blocks, the final cutting can be done with huge diamond tipped cutting wheels, or gang- sawed into slices with similar wire, water and abrasives. The bulk of limestone is mined for cement production, gravel, and soil conditioner. In these cases, surface mines blast free the stone to make it more manageable to move and transport to a crusher. Crushed material is stored on the ground and loaded as necessary to trucks for distribution to customers.
Limestone is the skeleton remains of minute shelled sea creatures that died a very long time ago. They sank to form thick beds on the sea floor. The thick beds were put under tremendous pressure, and eventually turned into solid limestone. We quarry limestone to make cement, building blocks, gravel for road building, and many more uses.
The calcium carbonate found in limestone was originally extracted from the shells and skeletons of marine organisms such as corals, mollusks, and foraminifera that accumulated on the ocean floor over millions of years. These organisms extract calcium and carbonate ions from surrounding water to build their calcium carbonate structures, which eventually become part of limestone deposits through geological processes.
Limestone may be mined in a surface quarry, typically by drilling, blasting, and crushing the shot rock. In some areas, limestone mines are underground. In Florida, some limestone mines are under water- the rock is drilled, shot, and mucked while under water. Limestone may be crushed to aggregate sizes, or finely crushed to a powder state for agricultural limestone, or used a "mine safety dust" to control methane and dust in coal mines. Powdered limestone (calcium carbonate) may be roasted and hydrated to form quicklime (Calcium oxide or calcium hydroxide)
Sodium chloride (salt) is the most commonly extracted element from seawater. Other elements that can be extracted include magnesium, calcium, and potassium.
The rate of loss of limestone increased as the experiment progressed. Initially, the reaction between the acid and limestone was slower, resulting in a lower rate of loss. However, as more limestone was consumed and the surface area for the reaction increased, the rate of loss of limestone accelerated.
The mass of limestone will depend on its density. The average density of limestone is around 2.71 grams per cubic centimeter. You can calculate the mass by multiplying the volume (0.0249 L) by the density. Therefore, the mass of 0.0249 L of limestone would be approximately 0.0675 kg.
Limestone is typically extracted through mining operations that involve drilling, blasting, and crushing the rock to extract the desired deposits. Once the limestone is extracted, it can be processed and utilized in construction, agriculture, or other various industries. The extracted limestone can also be further refined into products like quicklime or hydrated lime.

Some natural resources extracted near Richmond, VA are limestone, sandstone, clay, and shale.
Nigerian States where deposit of limestone extracted for the production of Cement are Ogun State in the South West and Benue State in the Middle Belt of Nigeria
The calcium carbonate found in limestone was originally extracted from the shells and skeletons of marine organisms such as corals, mollusks, and foraminifera that accumulated on the ocean floor over millions of years. These organisms extract calcium and carbonate ions from surrounding water to build their calcium carbonate structures, which eventually become part of limestone deposits through geological processes.
Carbon release from limestone reservoirs into the atmosphere most often occurs through human activities such as mining and quarrying operations. When limestone is extracted and processed, it can release carbon dioxide into the atmosphere, contributing to carbon emissions.
Larger pieces are often cut and shaped at the quarry; however, smaller pieces are more typically cut and shaped at other facilities. Custom pieces are most often cut and shaped on the building sight.
Limestone is obtained through mining or quarrying. Large deposits of limestone can be found in many parts of the world and are typically extracted using heavy machinery and explosives. After extraction, the limestone is processed and crushed into various sizes for use in construction, agriculture, and other industries.
Limestone is not an ore. It is a sedimentary rock composed primarily of calcium carbonate. Ores are rocks or minerals that contain valuable elements or minerals that can be extracted for profit, such as iron ore or gold ore.
The method of extraction depends on the intended use. If for cement manufacture, or road metal, then blasting and crushing are appropriate. If for building stone, then sawing it with steel saws, is a common technique.
The most common rock in Cork, Ireland is limestone. The region is known for its extensive deposits of limestone, which is a sedimentary rock formed from the remains of marine organisms. It is widely used in construction and as a building material in the area.
concrete is formed from limestone by the combustion of the limestone (heating of the limestone)!
