ABSTRACT. Apatite (Ca 10 (PO 4) 6 F 2) is the most important phosphate mineral, and flotation is the main beneficiation method to separate apatite from its major gangue mineral calcite (CaCO 3).Till date, fatty acids and their salts have been widely used as collectors in the apatite/calcite flotation separation due to their low cost and strong Characterization of a complex carbonate-silicate apatite ore and its concentration by a two-stage anionic flotation method REM, Int.

Apatite–Calcite Flotation Separation Using Sodium N MDPI
Froth flotation is a commonly utilized beneficiation technique for effectively separating apatite from other gangue minerals, such as calcite. It is difficult to achieve good separation with fatty acid collectors due to their similar interactions with apatite and calcite. In this work, sodium N-lauroyl sarcosinate (SNLS) was used as the 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 Minerals Free Full-Text A Review of Flotation Separation of Mg

Abstract. The flotation performance (recovery and grade) of apatite particles in a Esfordi Phosphate Complex was investigated as a function of collectors' ratio and dosage, pH, depressant dosageThe samples for the flotation tests were ground to 80% passing in the 106µm screen. In the apatite flotation tests, corn starch, gelatinized with soda, was used as a depressant, at the 1000g/t dosage.

Interaction Features of Sodium Oleate and ACS Publications
Apatite ores are the most important phosphate materials used for the agricultural and livestock chemical production. With the global demand for phosphorous compounds, apatite and other phosphorus-bearing ores are being depleted. The main method of apatite ore enrichment at the moment is the flotation process, the efficiency Abstract. In this study, the separation of calcite and apatite was achieved by the depressant sodium pyrophosphate (SPP). Microflotation results showed that when using 20 mg/l sodium oleate (NaOL) as the collector, apatite could be significantly depressed by 120 mg/l SPP, and calcite remained floatable at pH 6.5–9.3.Effect of sodium pyrophosphate on the flotation separation of
