01 Barite mining process - handpicking process. After the raw ore is extracted, simple handpicking is a common barite mining process for many small barite mines. Some barite mines have a high geological grade and stable quality, so the qualified barite products can be selected by handpicking according to the difference in the color …
The next stage, i.e., the flotation of the mixed concentrates, has two options: a) regular flotation, where the fluorite is floated using fatty acid as the collector, while barite is depressed by dextrin, tannin or malysite; b) reverse flotation, where hydroxy sulfate ester is used as the collector to float the barite, while the target mineral ...

Barite (BaSO 4) and celestite (SrSO 4) are the end-members of a nearly ideal solid solution. Most of the exploitable deposits of celestite occur associated with evaporitic sediments which consist of gypsum (CaSO 4 ·2H 2 O) or anhydrite (CaSO 4). Barite, despite having a broader geological distribution is rarely present in these deposits.
