Flotation is mainly used for processing low-grade ore, associated ore, and tailings of difficult-to-separate barite. Flotation process include direct flotation and reverse flotation.
Therefore, in the flotation process of barite ore, both inhibitors and collectors play a very important role. Under conventional flotation conditions, the recovery rate of barite can reach more than 80%, and the collector also has good ing properties, so the activator and ing agent are rarely involved in barite flotation.
As a common salt mineral, the flotation process of barite can be divided into two types according to the adsorption form: one is to use anionic collectors such as fatty acid alkyl sulfate and ...
Lead-zinc (Pb-Zn) ores are often symbiotic together, and the flotation method is generally used for beneficiation. After the Pb-Zn ore is crushed to a certain particle size, the heavy medium is used to remove the large and low-grade waste rock, and then the enriched ore is processed by the flotation method.

In this study, a novel surfactant, dioctyl di-hydroxamic acid (DODHA), was found as an effective collector for flotation separation of fluorite, calcite, and barite. Results from flotation tests suggested that the effective enrichment of fluorite from calcite and barite could be realized without the addition of depressants.
Anionic flotation is the most efficient method to separate fluorite from barite in mineral processing while the critical point of successful separation lies on the depressant.

The flotation of rare earth minerals, which is of current interest in the mineral processing field, is challenging owing to the dissolution of gangue minerals. In this study, dissolved fluorite and barite species were found to significantly affect the flotation behavior of bastnaesite.
Abstract: In this study, a modified starch was utilized to selectively separate barite from fluorite. 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 in neutral solutions.
Fluorite, barite and calcite are important industry minerals. However, they often co-exist, presenting difficulty in selectively separating them due to their similar surface properties. In this study, valonea extract and sodium fluosilicate were used as depressants to selectively separate them by flotation, with sodium oleate as the collector. The single …
However, it is almost impossible to select the fine barite through the above-mentioned methods, and froth flotation is always used to process fine-grain barite ore as well as other fine minerals [2], [15], [16], [17]. The anionic collectors from fatty acids or their derivatives are usually utilized to collect barite [2], [7].
This paper proposes β-cyclodextrin (β-CD) as a depressant for the recovery of barite from waste drilling fluid. The recovery process was investigated through inverse flotation experiments, and the mechanism was analyzed using zeta …
Processing of fluorite ores is the process of separating fluorite concentrate from fluorite ore. Fluorite, also known as fluorspar, has a chemical composition of CaF2, which is usually symbiotic with quartz, calcite, barite, and clay. Fluorite is mainly used as a slag-making flux for steel smelting in the metallurgical industry, and the ...

The relatively similar physicochemical features and floatabilities of fluorite and barite in the flotation process make the separation of these two minerals rather difficult.
The commonly used barite flotation methods include positive flotation and reverse flotation. Positive flotation.
