flotation separation fluorite

Flotation separation of fluorite from calcite by using ...

2020-12-1  The flotation separation of fluorite from calcite is realized when the adsorption amount on calcite surface is higher than that on fluorite surface (Tian et al., 2019a). Nevertheless, the depressive effect is greatly affected by the pH value ( Tian et al., 2019a ), with the excellent selective depressive effect only achieved in the pH range of 5.0–7.0.

Flotation Separation of Scheelite from Fluorite Using ...

2017-6-16  However, Flotation separation of scheelite from fluorite is difficult because of the existence of the same cation in the minerals and similar physicochemical characteristics such as solubility, hardness, specific gravity, and PZC (point of zero charge) [2]. Flotation techniques have been extensively applied to separate scheelite and fluorite.

Effect and mechanism of Cu(II) on flotation separation

2020-5-1  The presence of fluorite makes the flotation separation of cassiterite a very challenging work because the conventional collectors for cassiterite also float fluorite well, such as fatty acids, hydroxamic acids, phosphonic and phosphinic acids, sulfosuccinamate and sodium dodecyl sulfate , , , , , . So the flotation separation of cassiterite from fluorite is a valuable research issue.
