A carbonate-rich lake solution to the phosphate problem of

Modern carbonate-rich lake environments are some of the most productive ecosystems on Earth in terms of biomass turnover because of high nutrient levels . As a result, phosphate measured in modern carbonate-rich lakes is probably a minimum because microbes consume the phosphate and eventually deposit it in organic matter.

Removing Struvite from Wastewater Systems Modern

The higher the acid content, the lower the pH value. The solubility of calcium carbonate is directly affected by the pH of the water. If the pH of the water is decreased, more calcium carbonate solid can be dissolved. Conversely, if the pH of the water rises, it will force calcium carbonate out of solution and hence scale deposits will form.

Calcite Mineral Uses and Properties

Calcite as Limestone and Marble. Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis.

University of Minnesota's Mineral Pages Calcite

Rocks rich in calcium carbonate are heated to high temperatures so the CaCO3 will burn to form CaO and CO2 gas. The CaO can then be recombined with water (which always holds some dissolved CO2) to precipitate CaCO3 as plaster, mortar, and more recently as cement. Early Roman and Greek frescos attest to the use of lime in art as well.
