Recovery of Low Grade Barite Ore by Flotation in the …
The flotation results show that a barite concentrate assaying 98.21% BaSO4 can be obtained with the recovery of 80.71%. The agent used in the flotation is water glass as depressant at 500 g/t, sodium oleate as collector at 700 g/t. In the closed circuit, one rougher, three cleanings and one scavenging operations were employed. ...

Froth flotation of fluorite: A review
Therefore, fluorite and barite exhibit similar floatabilities, and their separation by flotation is difficult [169, 170]. Multiple flotation stages are usually required. The first step is to enrich fluorite and barite through mixed flotation in which sodium oleate and sodium silicate are selected as the collector and depressant, respectively [171].

Calcite in froth flotation
However, the flotation efficiency of ultrafine calcite particles (−20 μm) is very low and is mostly influenced by the entrainment mechanism [21]. Fatty acids and their derivatives are typically used as collector reagents for direct calcite flotation separation from other salt-like minerals (apatite, scheelite, barite, and fluorite).

Mineral Co | Barite
The term "primary barite" refers to the first marketable product, which includes crude barite (run of mine) and the products of simple beneficiation methods, such as washing, jigging, heavy media separation, tabling, flotation, and magnetic separation. Most crude barite requires some upgrading to minimum purity or density.
