Processing and production of industrial fillers based on calcium carbonate UK calcium carbonates are a nationally significant source of raw materials. Commercial calcium carbonate grades, in the form of powders, granules and slurries, are produced in 2 ways: through the extraction and processing of natural ores or synthetically through chemical precipitation.

Calcium carbonate is the average salt formed by strong base (calcium hydroxide Ca(OH)2) and weak acid (carbonic acid H2CO3). Aqueous solutions of CaCO3 have a weak alkaline reaction. Chemical properties of potassium hydroxide are similar to the properties of the carbonates of other metals .

Calcium Carbonate (CaCO3) is one of the most common scales in oil field operations. Various fluids (brine, oil and gas) can mix in the reservoir and/or wellbores under drastically varying sets of thermodynamic, kinetic and hydrodynamic conditions that will affect the carbonate scale forming tendencies.
