Two polymorphs of calcium carbonate (aragonite and calcite) were used during the solid-state process of ball milling. Structural analyses confirmed the mesocrystal formation of ibuprofen with aragonite but not with calcite. The origin of the observed behavior was found from the higher affinity of ibuprofen to aragonite, especially its (0 1 0 ...
Calcite readily dissolves in diluted hydrochloric acid or vinegar. It is also slightly soluble in water, which causes dillution and reprecipitation of calcite along fissures in limestone rocks. These processes lead to the formation of karst landscape with famous caves and dripstones. Similar processes cause the corrosion of concrete.
The milling circuit is the complete mill system from beginning to end, including feed mechanism, mill, classifier, separator, product collector, etc. In a closed mill circuit the oversize particles are returned from the post milling processes to be remilled (see figure below) whereas with an open circuit the process has no feedback loop.

Calcite powders were prepared from black marble waste by milling and alkaline hydrothermal processes. Crystal modifiers including two sulfates and an organophosphate chelator were used to study their effects on the crystallinity and particle morphology of calcite powders.
In African Pegmatite's facilities, this process is done on a large scale, but hammer milling can be done on a small scale. Roller Mills Roller mills are one of the most effective milling machines when it comes to crushing calcite, feldspar, gypsum, clay, marble, glass, or other materials into a fine powder.
Thus, the combination of milling process and hydrothermal treatment could be a universal processing route for the recycling of marble wastes into high brightness calcite powders. The white-colored calcite powders from the light-yellow marble and black marble are suitable for such applications as paints, plastics and tyres (Marras and Careddu ...
