Barite deposit at Mangampet is one of the world's largest deposits containing around 61 million tonnes of recoverable barite. Beneficiation of low grade barite dumps interlocked with schist and slate gangue was studied using amine as collector (reverse flotation) to avoid the collector coating on barite. Instead of conventional flotation cells, flotation column …
A mechanism model of flotation separation of barite with SDS as a collector and β-CD as a depressant is established, moreover, the possible reasons for the selective adsorption of β-CD on the barite surface are as follows:(a) β-CD requires less electrostatic repulsion to overcome when adsorbed on the barite surface; (b) the adsorption of β ...

The above results suggest that flotation separation of barite from calcite can be realized when the AWG is used as a depressant for calcite. Hence, flotation tests of barite and calcite mixture with the mass ratio of 4:1 were performed in the present and absence of AWG using NaOl as the collector at pH ˜8, the result of which is shown in Table 2.

Fluorite is easily affected by the slime coating of fine barite during the froth flotation separation. In this work, the water glass (WG) was utilized as a dispersant to improve the flotation ...
minerals are similar, which makes the flotation separation between barite and fluorite very difficult. The focus of this flotation is to identify surfactants with strong collecting power and high ...
Barite has numerous applications including barium mud for oil well drilling, manufacture of elemental barium, filler for paper and rubber industries, and contrast material for X-ray radiology for the digestive system. Currently, froth flotation is the main method for the beneficiation of barite using fatty acid as a typical collector. In this research, it was found that …
Microflotation showed that CA exhibited selective depression for fluorite, which allowed the preferential flotation separation of barite from fluorite at pH ~ 8.5. Real ore flotation confirmed that the separation of barite from fluorite could be achieved using CA as the depressant. A barite concentrate with 92.03% grade and 84.58% recovery ...

Flotation separation of the barite from calcite by adding depressant acidified water glass (AWG) and collector sodium oleate (NaOl) was investigated in this study. The micro-flotation results presented that NaOl has a good collecting ability for both barite and calcite while AWG has the selective depressing ability of calcite.
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 ...
When Zhou Yanhong [13] et al.studied the associated ore of high calcium fluorite-barite, a barite concentrate with a grade of 89.03% and a recovery of 81.95% was obtained by using the mixed flotation-rock shaker gravity separation process with the compound high-efficiency reagent EMY-326 F as the barite inhibitor, and good beneficiation indexes ...
