The Uses of Limestone

Construction

Limestone is the most widely used building material in the world. It is used as a raw material in building materials, e.g. bricks, plaster and cement. Lime is used for soil stabilisation, aggregates in road construction and limestone fillers in asphalt.

Metals & Mining

Limestone and lime are used in various processes in metals, mining and steel industries.

Pulp & Paper

Lime is used in pulp industry’s causticising cycle. Limestone is used in paper pigments PCC (Precipitated Calcium Carbonate) and GCC (Ground Calcium Carbonate)

Agriculture

Limestone is needed to adjust the pH value of the soil and making it optimal for growing plants. It is also included in fodder for poultry and livestock.

Environmental

Increased environmental demands require more advanced technology and purification of emissions to air, water and soil. Limestone is used for all of these processes.

Chemical Industry

Limestone is used in chemical products, plastic, rubber, paints and coatings,fertilizers, adhesives, glass and ceramics, and sugar.

The Limestone Value Chain

Timeline

1898

The Beginning

On November 26 1898, the Board of Directors of Pargas Kalks Aktiebolag gathered for their first meeting.

The limestone that was quarried in Pargas was burned and sold to paper mills, ironworks and pulp factories and in the 1910s a start was made on manufacturing cement. Crushed limestone was used primarily for agricultural purposes

1910

Operations begin in Lappeenranta

In 1910 Pargas Kalk also began operations in Lappeenranta and built the first shaft kiln. Since the beginning the two towns have formed the core of company’s lime operations in Finland.

1940s-50s

Expansion in Finland

In the 1940s and 1950s expansion of activities in Finnish construction material industry.

1970s

Name Change

Until the end of the 1960’s and even into the 1970’s, lime continued to be used as building material, in the pulp industry and as agricultural lime. But when Finland got a modern steel industry the need arose for new kinds of burnt lime. It was then that the development of new products and processes began, a trend that continues even today. In the 1970’s, the company also invested heavily in developing competitive agricultural lime, and the quarries in Siikainen and Vampula came into the picture. 

In 1978 Pargas Kalk changed its name into Partek.

1980s

Expansion to Sweden

In the early 1980’s, the largest deposit of limestone in the Nordic countries, Storugns on the Swedish island of Gotland, was incorporated into Partek’s operations through the setting up of a joint venture with Euroc Mineral.

In the mid-1980’s, Partek’s lime operations had grown so strong that Partek made its goal to become the leading producer of limestone-based products in the Nordic region.

1991

Nordkalk Oy Ab becomes an independent company

Partek’s lime business was turned into an independent company, Nordkalk Oy Ab, in August 1991.

1990s

Expansion to Baltics and Poland

A limestone quarry and a dolomite quarry were purchased in Estonia, and in 1998, Nordkalk took over the leading Estonian producer of calcium oxide, Rakke Lubjatehase AS.

Nordkalk started its expansion in Poland and opened its first branch office in Gdansk in 1997. The company was named Partek Nordkalk Polska Sp. z o.o. In 1999, a lime plant and a deposit were acquired in Slawno, about 120 km south-east of Warsaw.

2000s

Expansion in Poland

A new grinding plant in Szczecin in Northern Poland was brought into use in the beginning of the year 2000.

Nordkalk acquired a limestone company in Miedzianka, Southern Poland. It included one of the largest limestone deposits in the country. The deposit of Wolica in southern Poland was granted mining rights and a new mill was completed in 2001.
