Limestone is a sedimentary rock comprising about 15% of the earth’s sedimentary crust. Limestones are generally mined in the method of open pit mining and underground mining based on the economic and environmental conditions. WHERE DO THEY FORM LIMESTONE : Limestone is formed in a variety of marine, freshwater and terrestrial environments.Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.Limestone Quarrying and Processing: A Life-Cycle InventoryThe primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.How do we extract minerals? | U.S. Geological Survey - USGS.govاحصل على السعر
