combined effect of relevant process variables to maximize the production of calcium carbonate in a batch reactor. The process variables include time (0, 60, and 120 min); slurry content (5, 10, and 15%); agitation speed (100, 300, and 500 rpm); and sodium carbonate/gypsum molar ratio (,, and 2). In the optimum conditions of the process (the slurry concentration of 5%, .

Three major technological processes are used in the production of calcium carbonate fillers: milling, precipitation, and coating. However, most calcium carbonate fillers are processed by milling using a dry or wet method. Dry milling provides ultrafine calcium carbonate grades (particle size about μm). Natural milled calcium carbonates are added to decrease cost in .
