Flue dust, portland cement A complex combination of finely divided inorganic particles separated from the exit gases formed during the manufacture of Portland cement. The flue dust consists of uncalcined raw materials along with partially calcined materials. Some Portland cement clinker is usually included. The major constituents of kiln dust are calcium carbonate, clays, shales, quartz and sulfate salts.

Cement, alumina, chemicals High-Alumina cement is a mixture of chemical substances produced by burning or sintering at high temperature (greater than 1200°C (2192°F)) raw materials which are predominantly calcium carbonate, aluminium oxide, silica, and iron oxide. The chemical substances which are manufactured are confined in a crystalline mass. This category includes all of the chemical substances specified below when they are intentionally manufactured in the production of high-alumina cement. The primary members of this category are CaAl2O4, Ca4Al2Fe2O10, Ca12Al14O33, and Ca2SiO4. Other compounds listed below may also be included in the combination with these primary substances.@CaAl4O7@Ca2Al2SiO7@CaAl12O19@Ca4Al6SO16@Ca3Al2O6.@Ca12Al14Cl@CaO@Ca12Al14F2@Ca3SiO5@Ca6Al4Fe2.@Ca2Fe2O5.

Flue dust, precious metal refining The dust obtained from the refining of materials from primary and secondary sources containing gold, iridium, osmium, palladium, platinum, rhenium, ruthenium and silver. Composed primarily of lead with traces of other metals.

Residues, calcium sulfate-contg., flue gas wet desulfurization neutralization Residue rich in calcium sulfate obtained during the desulfurization of flue gases of bituminous coal or oil-fired boilers of power plants. Composed primarily of calcium sulfate with chlorides, fluorides, trace element oxides as well as pure gas dust components from the combustion process.
