Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either …
Limestone. Perhaps the most widely used type of natural stone, Limestone comes in a range of geological forms. It occurs naturally in many parts of the UK but the main belt runs from Dorset and Somerset in the South West, through to the Cotswolds and Oxfordshire and then on into Northamptonshire, Lincolnshire and north of the Humber.
The Earth's crust contains metals and metal compounds such as gold, copper, iron oxide and aluminium oxide; Useful metals are often chemically combined with other substances forming ores: A metal ore is a rock that contains enough of the metal to make it worthwhile extracting

As a rule of thumb, in order to produce a tonne of clinker about 1.6 tonnes of limestone is processed, i.e., around 3.5 to 5.5 MTPA of limestone is required and assuming a minimum plant life of 30 years each modern clinkering unit would need an assured limestone deposit of more than 100 to 150 MT.
A new method for combatting climate change feels like a bit of modern-day alchemy: scientists have figured out how to take carbon dioxide out of the ocean and turn it into harmless rock.

In modern times several new techniques are used to extract the mineral from the ore, in addition to smelting. The most common methods are flotation, leaching and use of redox reactions. Leaching involves mixing the ore with a carefully chosen liquid that dissolves either the mineral or the unwanted minerals. The liquid is often an acid.
