Ca = calcium.
CaCO3 calcium carbonate = limestone.
Ca(OH)2 calcium hydroxide = slaked lime.
CaCO3 • MgCO3 calcium magnesium carbonate = dolomite.
CaO • MgO calcium magnesium oxide = burnt dolomite.
CaO calcium oxide = quicklime.
MgO magnesium oxide = refined burnt dolomite
Mg(OH)2 magnesium hydroxide = brucite.
Acidification = reduction of the pH of soil, waterways and lakes.
Active calcium oxide = free lime that can react chemically.
Agricultural lime = lime and dolomite products that are used in agriculture to raise the pH of the soil.
Building lime = binder for building mortar.
Calcination = heating material to release volatile constituents or change the crystal structure.
Calcite = crystalline mineral consisting of calcium carbonate.
Carbonate rock = type of rock consisting mainly of carbonates.
Coating pigment = pigment for coating paper (usually supplied as slurry. Mixture of very bright, clean particles, such as pulverised limestone or kaolin).
Dolomitic limestone = limestone that includes small amounts of the mineral dolomite.
Dolomite stone = type of rock which consists mainly of the mineral dolomite.
Filler = fine ground limestone or dolomite stone. Used as a filler in asphalt, plastics, paint and paper, for example.
Flotation = chemical/physical separation process carried out in a water slurry.
Flue gas cleaning = removal of environmentally harmful substances from flue gases.
Fossil = relic of an organism embedded in sediment.

Garden lime = limestone or dolomite. Crushed or agglomerated for garden use.
Hydraulic lime = binder for plaster and mortar.
Lake liming = spreading of pulverised limestone used to combat acidification in lakes.
Lime-burned dolomite = calcinated dolomite stone with a carbon content similar to that of normal roast limestone.
Lime mud = precipitated calcium carbonate from the chemical recovery line in the sulphate pulp mill.
Lime mud kiln = rotary kiln for calcination of lime mud.
Limestone = type of rock that consists mainly of the mineral calcite.
Magnesium oxide = burnt dolomite refined to MgO. Used for purposes such as fertilizer, forage and in the pulp and paper industry.
Magnesium hydroxide = brucite (naturally occurring mineral) or synthetic (precipitated from sea water).
Metallurgical lime = quicklime. Slag-former and lining protector used in metallurgical processes.
Mg limestone = mechanical mixture of limestone and dolomite. Used as a liming agent in agriculture and forestry.
Mineral = homogeneous, inorganic substance formed by natural processes. Part of earth’s crust.
Neutralisation = elimination of excess H+ or OH- ions by adding base or acid.
PCC = Precipitated Calcium Carbonate.
Primary dolomite = carbonate rock formed in early geological age. Later converted by metamorphosis.
Quick lime, burnt lime = lime product consisting mainly of CaO. Produced from limestone from which carbon dioxide has been removed by heating.
Slurry = particles in suspension.
Sulphur absorber = binds sulphur in flue gases to form a solid phase that can be removed. |
