In this work, experiments were performed to determine the filterability of calcium carbonate produced with an alternative calcium carbonate production concept. The concept uses steelmaking slag as raw material and has potential to fix CO2 emissions and utilize steelmaking slag, simultaneously. As calcium carbonate is precipitated in a …

Theory and figure for separate calcium carbonate from mixture of sand and calcium carbonate Sands are tiny solids, whereas rocks are larger. As a result, handpicking can readily separate them. Sand and rocks can be easily separated from one another by hand-picking the rocks out of the mixture and setting them aside or in separate containers.

How is the calcium dissolved so that only the SiO 2 (sand) is left behind? The solid after the first filtration is a mixture of sand and calcium carbonate. To this solid, you add HCl. The HCl reacts with CaCO 3 to form CaCl 2. You then add K 2 CO 3 to the aqueous solution of calcium chloride to recover the CaCO 3.

To summarise: Use simple distillation when you want to separate the solvent from the solute - i.e. water and salt in seawater. Use fractional distillation to separate two or more liquids mixed together - i.e. liquid ethanol and liquid water. Use filtration to separate a liquid and a solid - i.e. calcium carbonate and water, or sand and water.

Calcium carbonate is fairly insoluble stuff. If you want the solid use a Buchner funnel; the solution may be decanted. The process of filtration can also be used for this separation. The solubility of calcium carbonate is quite pH dependent. Clearly, lower pH values would increase solubility of the salt in that the acid would decompose …
