This process involves synthesis of calcium levulinate by treatment of Mytilus galloprovincialis shells with levulinic acid. The advantage of mussel shell utilization results in more straightforward qualitative composition. Thus, the weight of the mineral component lies with calcium carbonate, which can be used for extraction of …
The precipitated calcium carbonate production process consists of decarbonating limestone, which separates the CaO (calcium oxide) and CO 2 (carbon dioxide). …
Calcium carbonate material from limestone and eggshells powder was ground using the developed ball mill. The balls to powder ratio (BPR) and powder type were investigated in relation to the particle size. The study showed that the combination of the BPR and powder type affects the particle size result.
