Limestone is an essential raw material
Limestone-based products - usually referred to simply as lime - are needed in many different industries, in environmental care and in agriculture. Nordkalk's main products are limestone, crushed and ground limestone, concentrated calcite, quicklime and slaked lime. The products also include dolomite and a rare mineral called wollastonite, which is found together with limestone.
Limestone, Purifying Natural Product
Originally, limestone is a sedimentary carbonate rock consisting mainly of calcite mineral i.e. calcium carbonate (CaCO3). Pure limestone contains 95 to 100% calcium carbonate. Limestone is one of the most common rock types, except for in Nordic bedrock areas in, where limestone deposits are limited.
Limestone is a pure natural product, which can be used unrefined, either crushed or ground.
When refined into calcium oxide (CaO, quicklime) or calcium hydroxide (Ca(OH)2, slaked lime) the reactivity of lime increases as does its ability to absorb impurities. Limestone-based products are used to remove impurities in different processes and as neutralisation agents. The importance of this kind of cleantech solutions, which decrease environmental impacts, is growing.
Nordkalk is the leading limestone company on its home markets. We deliver essential raw materials to numerous industries, and our solutions contribute to clean air and water as well as productivity of agricultural land.
