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 …

It is hard to separate barite from fluorite due to their similar surface properties. In this work, to achieve the separation of barite from fluorite, 2-phosphatebutane-1, 2, 4-tricarboxylic acid (PBTCA) was used to depress fluorite, and the floatability, separation efficiency and mechanism were researched by micro-flotation …

The results of flotation tests showed that highly selective separation of fluorite from barite was obtained when 250 mg/dm³ of modified starch and 13.16×10⁻⁵ mol/dm³ sodium oleate was used ...

Barite is a critical mineral that finds applications in many industries. The mineral is commonly occurred in deposits formed in a variety of geological environments where other semi-soluble minerals such as calcite and fluorite are also present. Because of decreasing ore grade, the mineral processing of barite nowadays becomes increasingly …

Fluorite (CaF2), as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough. The development of a selective collector and/or depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP …
