2019-1-23  Abstract: The flotation separation of barite from calcite using sodium dodecyl sulfate (SDS) as the collector and sodium silicate (SS) as the depressant has been concretely studied in this paper. The results show that SDS has high collecting ability for both barite and calcite and that the flotation separation of barite from calcite cannot be achieved by using SDS alone. The depressant sodium

Here Are All flotation Separation Processes for

2021-2-4  (1) Inhibit barite and separate fluorite by flotation. After obtaining the bulk concentrate of barite and fluorite, aluminum sulfate, water glass and tannin extract are used as a combined inhibitor of barite, and the fluorite and barite are separated by one roughing and several flotation processes. This method obtains a higher grade of barite concentrate, but a relatively low grade of fluorite. (2) Inhibit fluorite and separate barite
