In conclusion, calcium carbonate and titanium dioxide are important minerals that are used in various industries. While they are both produced by manufacturers, they have different manufacturing processes and applications. Understanding the differences between these two minerals can help industries make informed decisions about which one to use for their specific needs.

Titanium dioxide can amplify and brighten white opacity because of its exceptional light-scattering properties. In food and drugs, these properties help to define colors clearly and can prevent products from UV degradation. 

It's also used in sunscreens as a UV filtering ingredient, helping to protect a person's skin by blocking absorption the ultraviolet light that can cause sunburn and cancer.
