Ba2+ cations are the potential determining ion (pdi) for barite and BaCl2 increases the efficiency of barite flotation (Schubert & Schneider, 1970). Barite is suppressed with …
Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …
1. Introduction. Barite is the most common barium-bearing mineral with the chemical formula of barium sulfate (BaSO 4), which usually derives from low-temperature hydrothermal veins and sedimentary rocks [1], [2].For the sake of special physical and chemical properties, barite could be used as an important non-metallic raw material in …
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 …
Flotation experiments were performed using labora-tory Denver D12 flotation cell in 2 stages. First, lead was separated, and then barite flotation tests were performed on the final tailings of lead tests. 2.2.2.1. Lead flotation tests In lead flotation, 1-kilogram samples recovered from Mozley gravity separator tests, to optimize different pa-

For instance, Grigorova et al. used froth flotation to obtain refined barite samples with a BaSO 4 composition of 95% from Kremikovtzi "black" tailings. In another study, Afolayan et al. ( 2021 ) used local processing methods to beneficiate barite ores and their findings showed that the processed barite contained 87.79% BaSO 4 and 6.66% …
The next stage, i.e., the flotation of the mixed concentrates, has two options: a) regular flotation, where the fluorite is floated using fatty acid as the collector, while barite is depressed by ...
Beneficiation of Barite Ores. Srdjan M. Bulatovic, in Handbook of Flotation Reagents: Chemistry, Theory and Practice, Volume 3, 2015 Abstract. Barite is the only barium mineral used in the production of BaSO 4 of various purities. Barite is not only produced from primary barite deposits, where barite is the primary mineral but there is a growing trend …
The aim of this study was to find optimal models in a comparative framework to estimate the recovery and grade of barite concentrate obtained from the rougher …
The grade of the barite concentrate retrieved did not satisfy the API barite requirements.The fineness of the tailings and the fact that approximately 80% of the barite was contained in the -200 mesh (0.074 mm) size fractions, indicated that flotation of barite from the tailings might be successful."
The results of mineralogical, physical and chemical characterizations revealed the presence of 3.82% lead and 49.60% barite in waste rocks, and 62.73% barite in tailings.
"Tailings from lead-zinc mine contain plenty of dolomite and low-grade fine-grained barite, which is difficult to enrich by mineral processing. Since the density of barite and dolomite has some differences due to the fine dissemination size in a complex sedimentary, the gravity separation tests were conducted with no results obtained. The …

Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New Concentrator in Kipushi (NCK). Metals retention in the tailings (0.73% Cu and 0.37% Co) increased due to the removal of the gravity separation section from the processing circuit together with …
This review examines the current state of barite in terms of its properties, resource type, production and processing using froth flotation, suggesting there are …
The results showed that after the microwave pretreatment, the flotation indexes of barite were all increased to a certain extent, and the recovery rate of barite was higher than 78% under the ...
The aim of this study was to find optimal models in a comparative framework to estimate the recovery and grade of barite concentrate obtained from the rougher flotation of the barite tailings.
Barite is an important strategic non-metallic mineral. China has rich barite resources. Its reserves, output and export volume rank first in the world. However the situation of low export price has existed for a long time. Based on the characteristics of barite ore at the present stage, this paper introduces the different dressing methods of …
complement rather than replace flotation size bubbles (Nesset et al., 2006). Research has shown that the ageing of micro (pico) bubbles as well as flotation sized bubbles was detrimental to particle-bubble attachment and that future the optimum flotation conditions would be obtained under conditions in which the two are co-generated.
