Calcium carbonate - Essential Chemical Industry

Traduire cette page

Three types of calcium carbonate-containing rock are excavated and used by industry. They are limestone, chalk and dolomite. Limestone and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates. All have impurities such as clay but some rocks are over 97% pure. Limestone and other products derived from it are used extensively in the construction ...

This indicates that carbonate may decrease the precipitation rate and efficiency of calcium phosphate, but the solution pH value is still a key factor influencing the precipitation process. The effect of carbonate on the precipitation of phosphate was attributed to the formation of ion pairs between carbonate and calcium and the decrease of free calcium ions. This resulted in the decrease of ...

Calcium carbonate scaling of digesters and black liquor evaporators is the most frequently identified inorganic deposit problem in the kraft cycle. Scale buildup on heat exchangers leads to increased steam usage in the digester and reduces production of strong black liquor at the evaporators. Digester scaling also reduces liquor flow rates, which generates fluctuating kappa numbers and ...

Calcium bicarbonate, also called calcium hydrogen carbonate, has a chemical formula Ca(HCO 3) 2.The term does not refer to a known solid compound; it exists only in aqueous solution containing the calcium (Ca 2+), bicarbonate (HCO − 3), and carbonate (CO 2− 3) ions, together with dissolved carbon dioxide (CO 2).The relative concentrations of these carbon-containing species depend on the pH ...

Calcium carbonate from geological sources (geo-CaCO3, e.g., calcite, aragonite) is used extensively in removing heavy metals from wastewater through replacement reaction. However, geo-CaCO3 has an intrinsically compact crystalline structure that results in low efficiency in pollutant removal and thus its use may produce enormous sludge. In this work, biogenic calcium carbonate (bio-CaCO3 ...
