The ash residue is a granular mixture of calcium oxide, calcium sulfate and small amounts of metal oxides. Other industrial by-products that contain calcium hydroxide include flue dust from cement manufacturing, pulp mill lime, carbide lime, and by-products from the tanning industry (Tisdale, 1985; 2) use as a source of nitrogen, phosphorus

3.2.6 Group 2, the Alkaline Earth Metals - Trends in

The relative solubility of the metal sulfates. Unlike the group 2 metal hydroxides, the sulfates become less soluble on descending the group, with magnesium sulfate the only truly soluble sulfate of the group. Calcium sulfate is only sparingly soluble and is often described in texts as insoluble.

WebElements Periodic Table » Calcium » the essentials

The calcium chloride is made by the action of hydrochloric acid upon calcium carbonate. Calcium chloride is also a byproduct in the Solway process used to make sodium carbonate. CaCO 3 + 2HCl → CaCl 2 + H 2 O + CO 2. Alternatively, and on small scale, calcium can be made through the reduction of CaO with aluminium or of CaCl 2 with sodium metal

Calcium carbonate - Essential Chemical Industry

Very fine and pure calcium carbonate is used as filler in plastics and paper. A filler is a substance that gives bulk but does not alter the properties of the substance to which it is added and is also inert. Calcium carbonate when very finely crushed (less than 2 microns) is used in paints to give a ''matt'' finish. Figure 8 Uses of limestone.
