Luckily, calcium carbonate is easily dissolved in a range of mild acids.

Minerals Technologies produces calcium carbonate, used to whiten everything from paper to talc.

In more acidic water corals have difficulty secreting their reef-building calcium carbonate shell.

Scattered in the muck around it she'd seen lumps of calcium carbonate: chalk.

Normally, foraminifera build hard shells of calcium carbonate to protect themselves.

And when calcium carbonate mixes with acid, it fizzes like crazy.

The doses of calcium carbonate per se have no deleterious effect (2).

The calcium carbonate, being insoluble, is easily separated from the caustic liquor by filtration.

And just like that abalone is going to grab calcium and build calcium carbonate.

If it's the first, I'll build scaling walls out of salt or calcium carbonate.

Effects of calcium acetate on biochemical end points were similar to those of calcium carbonate.

Thus lime ( calcium oxide) is made by strongly heating calcium carbonate:

The grain is then spread on a disinfected muslin cloth and mixed with calcium carbonate.

Chalk is composed of tiny calcite ( calcium carbonate) plates called coccoliths.

That damages hard corals, tiny animals that secrete calcium carbonate to form their stony protective layer.

It is slowly decomposed by the carbon dioxide of the air, yielding calcium carbonate and chlorine:
