- Processing Calcium Carbonate caco3 Wet Milling
Calcium carbonate (CaCO 3) has been widely studied due to its chemical stability and mechanical reinforcement ability (Chen et al. 2010 and Tanniru et al. 2005).CaCO 3 is one of the cheapest commercially available inorganic materials (Kumar et al. 2014), and therefore has innumerable industrial applications: it is used in paints, inks, …

Abrasion characteristics of any material are a function of hardness, concentration and particle size. Hardness is typically measured on the Mohs scale, where a diamond is 10 and talc is 1 (Figure 1). A higher Mohs hardness will scratch or abrade a material with a lower number. Calcium carbonate is a soft mineral with a Mohs …
