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. |
