calcium carbonate processing flotation

Flotation behavior and mechanism of calcium carbonate ...
2022-1-1 · Calcium carbonate frequently coexists with other calcium-bearing minerals in single or multiple crystal forms. The crystal structure and surface properties of calcite and aragonite are dissimilar, leading to differences in flotation behavior when calcium carbonate polymorphs are separated from other calcium-bearing minerals.
