The froth products were collected with an automatic …
In this study, to improve the removal efficiency of dolomite from apatite by direct flotation, hydrolytic polymaleic anhydride (HPMA) was introduced as an eco-friendly depressant for dolomite.
Selective flotation separation of apatite from dolomite utilizing a novel eco-friendly and efficient depressant for sustainable manufacturing of phosphate fertilizer
The flotation behaviors of magnesite and dolomite with single or mixed collector were investigated through micro-flotation tests. The co-collection mechanisms …
This study focuses on the effects of ultrasonic treatment on the surface roughness, flotation behavior, and flotation separation efficiency of magnesite and dolomite in a sodium oleate (NaOL) system. Flotation experiments show that ultrasonic treatment improves the flotation recovery and separation efficiency of these two minerals.
The micro-flotation test results indicated that saponified 2-DMPT exhibited a stronger collecting ability and higher selectivity to dolomite compared to smithsonite under highly alkaline conditions, enabling efficient removal of dolomite from smithsonite through reverse flotation.
Flotation is a separation and concentrate method that uses the physicochemical features of minerals to separate valuable minerals from gangue …
The previously experimental and analytical results supported that the selective adsorption of P (AA-AMPS) onto dolomite depressed strongly the dolomite flotation, resulting in the efficient separation of apatite from dolomite.
The results of single mineral flotation experiments demonstrated that KGM selectively depresses the flotation of dolomite. Consequently, artificial binary mixed ore flotation studies of apatite and dolomite were conducted to investigate its selectivity and separation effect due to the varied flotation behavior of mixed ore.
Thus, this research offers a novel non-toxic and eco-friendly dolomite depressant, 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA), for selective …
Request PDF | Flotation studies of monazite and dolomite | Rare earth elements (REE) are key components of many emerging green technologies. This leads to an increase in demand for REE, hence to ...
It is difficult to effectively separate magnesite from dolomite owing to the similarity of their surface properties. In this study, a novel mixed collector of oleic acid and dodecyl phosphate was used to increase the flotation …

Flotation Separation of Dolomite from Fluorapatite Using Sodium Dodecyl Benzene Sulfonate as the Efficient Collector under Low ... orapatite/dolomite was added in the flotation cell with 50 mL pure water, and then stirred 2 min for dispersion. ...
It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg …
To address the flotation separation problem between apatite and dolomite, DMNS (disodium methylenebis naphthalene sulfonate) was selected as a depress…
In this work, GJBW, a fatty acid-based agent, was used as an efficient collector to separate dolomite from apatite to achieve high-purity apatite. The flotation …
nosulfonate dosage on the flotation of apatite and dolomite is investigated. Fig. 5 shows that calcium lignosulf-onate has depressant effect on oth apatite and dolomite, but the …
To assess the efficacy of a reagent system employing NaPP as an inhibitor and 2-Cl-9-ODA as a collector in the reverse flotation separation of apatite from dolomite and calcite, flotation experiments for each single mineral were performed. The equipment used in the micro-flotation experiments was an XFG Ⅱ-35 flotation machine.
In this study, sodium dodecyl benzene sulfonate (SDBS), a low‐cost and freely soluble reagent under low temperature was used to examine its collecting ability and selectivity …
Amino-acid-based surfactants are promising collectors for the flotation of calcium-bearing minerals.
