Limestone

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

Limestone uses — Science Learning Hub

Fillers in manufactured goods. This limestone is quarried and ground to a variety of sizes with diameters ranging from a fraction of a micron to several microns (1 micron = 10 -6 m). These fine powders find a multitude of uses as fillers in manufactured goods such as paints, plastics, cleansers, paper and carpets.

Environmental Hazards of Limestone Mining

Limestone mines use two types of blasting. Small explosive charges set along drilled lines free blocks of stone to be removed for construction. Large charges reduce whole areas of limestone to rubble, which is removed for use as crushed stone. The noise, dust, and impact from explosions can result in noise pollution and dust.

How Is Limestone Mined?

Limestone is surface mined through open pit quarries or hillside cuts, or horizontally by tunneling under the overlaying surface rock. Quarrying is the most common method used, because it is an easier and cheaper method for removing shallow deposits. Underground operations are used when the overlaying surface rock is too thick.

Limestone extraction

Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. If the site presents the desired conditions for quarrying, the next step is the licensing, a procedure which entails various environmental requisites.

quarrying

Introduction. Mining is the removal of minerals from Earth's crust. Quarrying is the mining of stone, or rock used mainly for building. A quarry is a hole or a pit in the ground from which workers remove stone. During quarrying, workers cut or blast stone into smaller pieces. These smaller pieces of stone are easier to handle and can be used to make many things.

limestone

Limestone is a type of rock that is made up of bits of animal shells. Over millions of years these shells collected on the ocean floor. As layers of shells and mud built up, the lower layers slowly hardened into limestone. Limestone is found all over the world.
