Limestone is a versatile commodity used to create products for agricultural, environmental, and industrial purposes. Cement, paint, soil amendments, and even breakfast cereals all contain this resourceful mineral. Of course, mined limestone is not naturally found in a suitable form for many of these products.
Limestone is a type of a sedimentary rock that is found naturally in the earth''s environment. The rock comprises primarily of chemical compound calcium carbonate (CaCO 3) in the form of calcite which is yet again a type of a also contains other materials like quartz, clay minerals, pyrite, feldspar, and siderite amongst others.
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and 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.
Silica occurs naturally in the earth, and it is a component of many construction and manufacturing materials. It is a health hazard only when it is airborne, and the crystalline silica particles are inhaled. Thousands of products contain silica (everything from makeup to pottery) but just containing silica does not make an item hazardous or a potential cause of illness.
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.
