However the flotation separation of barite from calcite is difficult to achieve because of the similar physical and chemical properties on the mineral surface which has led to the reduced selectivity of conventional collectors such as fatty acids and fatty acid derivatives Amakonah et al 1985; Fuerstenau et al 1992; Ozcan and Bulutcu
The flotation recovery curves for bastnaesite in BaCl 2 and the barite supernatant were very similar showing significant decreases in recovery under both acidic and alkaline conditions These results suggest that the flotation behavior of bastnaesite can be significantly affected by the species of dissolved gangue
Micro flotation results presented good recoveries of barite and calcite could be obtained using the individual NaOl and the presence of HPAA selectively depressed the calcite flotation while did not affect the barite flotation Barite/calite minerals mixture flotation verified that the addition of HPAA realized the high separation efficiency
In this study a novel collector oleate hydroxamic acid was synthesized in laboratory and applied to flotation separation bastnaesite from barite And its separation performance was explored by flotation experiments Furthermore the collecting mechanism of OLHA for both minerals were analyzed by contact angle zeta potential FTIR and XPS
The aim of our study is in a first step a systematic flotation behaviour of barite and associated minerals during which various collec tors combined with modifiers have been tested Then an artificial mixtures flotation was carried out and all the optimal conditions of flotation were applied to barite and fluorite barite ores
Oxidized paraffin soap C 12 16 COONa is also widely used in quartz fluorite calcite fluorite and barite fluorite separation by flotation Its collecting abilities are weaker than oleic acid but its selectivity is better The soap made from saponified waste oil can reach the flotation concentrate grade and recovery of ca 98% and 86%
In the past few decades several kinds of inhibitors have been studied in the flotation separation of fluorite and barite Specifically citric acid was found to strongly depress the fluorite flotation while it showed little influence on the barite flotation resulting in the selective separation of barite from fluorite Liu et al 2020
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 mineral flotation results
This study aimed to provide a novel fluorite depressant for flotation separation of barite fluorite ores and reveal the selective depression mechanism of IDS for fluorite Section snippets Materials and reagents The pure barite and fluorite were purchased from Guangzhou Guangdong Province China The bulk minerals were first crushed to the
Barite was recovered up to 87% at pH = 3 in sole mineral flotation experiments and flotation of the mixed sample also proved a successful selective separation of barite 76% recovery from
To achieve the efficient flotation separation of barite from fluorite citric acid CA was utilized as a depressant for fluorite in this study Microflotation showed that both fluorite and barite had good floatability when using sodium oleate NaOl as the collector while fluorite was selectively depressed when using CA as the depressant
As a result selectively depression of barite flotation and the flotation separation of fluorite from barite were achieved Therefore GG can be used as an efficient and eco friendly depressant to
The flotation chemistry of barite is critical in the separation of barite from apatite fluorite and bastnaesite For this reason the wetting characteristics lauryl phosphate adsorption phenomena and flotation response in barite flotation with lauryl phosphate were examined by contact angle and
The mechanism model of the flotation separation process was established 1 Introduction Barite BaSO Therefore the research results applied β CD to the flotation of barite for the first time which provides a feasible and economical process method for safe and optimal drilling resource recovery and utilization and green development in
4 2 Magnetic separation For barite ore containing magnetic iron minerals with fine particle size strong magnetic separation is often used to separate iron containing minerals and process has the advantages of high production efficiency low energy consumption and less environmental pollution
Effective flotation separation of fluorite and barite with the environmentally friendly surfactant caprylhydroxamic acid Xiao Wang Shuai Yuan Peng Gao Quankun Liu Pengcheng Tian Jiahao He Environmental Science Chemistry Separation and Purification Technology 2024; Save
Effective flotation separation highly depends on the selective adsorption of reagents on the mineral surface This research found that the novel hydroxamate based collector octylamino bis propanohydroxamic acid OPHA could selectively adsorb on fluorite surface thus rendering the effective flotation separation of fluorite from Macroscopic
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
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
OPTIMISATION OF BARITE FLOTATION PARAMETERS Na dodecylsulphate Sulfopon T35 and Petronate L have led to the separation of barite from calcite and quartz When the quartz and barite are
The concentration of barite by gravity separation generates substantial quantities of fine particle wastes and it is estimated that ≈40% of the contained barite is lost to these waste streams In this study froth flotation was examined as a potential method for the recovery of fine barite particles The study included the use of kinetic equations to estimate the variables
As a result selectively depression of barite flotation and the flotation separation of fluorite from barite were achieved Therefore GG can be used as an efficient and eco friendly depressant to
