Froth flotation is the most effective method to separate and enrich refractory calcium-containing minerals. Because the calcium ions in the mineral lattice are the same, they have similar surface chemical properties and dissolution characteristics (solution chemical properties) in the slurry environment [29], [30], [31], resulting in a lack of selectivity in the adsorption of flotation ...
