The degree of liberation of apatite in the tailing and the other minerals in all the flotation products was low. Monazite was mainly associated with the iron minerals especially ilmenite.
Froth flotation is the most important concentration method for beneficiating phosphate ores [2], [3].In this process, most collectors used worldwide are fatty acids obtained from vegetable species as byproduct of different industries, e.g., tall oil, a byproduct of the paper industry [4], [6].However, the investigations on alternative sources are being encouraged as …

Water from a tailing dam of an apatite processing industry has been treated by this technique and the produced water used in the flotation of apatite in column. Results have shown that the use of recycling water after the wastewater treatment proposed in this work led to a good performance of apatite flotation, leading to recovery (80.5%) and ...

To address the U.S. Department of Energy's critical minerals strategies regarding rare earth elements (REE) in the U.S.A. This study evaluated apatite-rich mine tailing from the historic Pea Ridge Iron Mine (PR) for possible enrichment of REE by the froth flotation process. Comprehensive characterization studies were performed on the tailing samples to quantify …
The concentration process produces a non-magnetic tailing containing apatite, with grades between 1–3% P[sub.2]O[sub.5] [9]. Flotation is a method based on the difference in physicochemical properties between valuable minerals and gangue [10]. The wettability of the surface plays a decisive role in its buoyancy.
On the other hand, both calcite and dolomite recoveries increase with rising collector dosages and higher pH values. They each reached recoveries exceeding 80% at pH 9 and using 1000 g/t of FrOC after 3.5 min of conditioning and 6 min of flotation. Under these conditions, apatite flotation did not exceed 6%.

It was demonstrated that metallurgical responses (recovery, grade, selectivity, and kinetics) of NB ...
A sample of apatite-bearing tailings was collected from the tailing dump of the Kovdor beneficiation plant in the Kola province of Russia. The sample was thoroughly mixed and homogenised to have a representative sample for chemical and particle size analyses, mineralogy characterisation, and flotation tests.
Conventionally, froth flotation has been used to separate phosphate minerals from interfering gangue via their distinct properties [7], [8].Significant research on the flotation of apatite has been conducted, but most previous studies focused on the flotation of single gangue minerals, and rarely considered the flotation of apatite containing silicon and calcium …
To enhance clarity, the study on pure apatite should be separated into the subsection, followed by the flotation of tailing contaning apatite, and finally, the kinetic study. …

Sedimentary phosphate occurs largely at Gafsa mining basin. Among these occurrences Jebel Alima (Redeyf region) is an open pit quarry. After extraction, raw phosphate requires several stages of treatments to become concentrated: crushing, grinding, scrubbing, sizing, attrition, de-sliming and flotation.
The coarse fraction circuit requires barite pre-flotation (one column), followed by apatite flotation (two columns in parallel); the tailings from these two columns are reground to improve the ...
This work presents the results obtained during flotation of fine-grained apatite-bearing tailings provided from the Kovdor concentration plant in a laboratory cell and a pilot-scale column.
Froth flotation is one of the main methods for processing of phosphate ores. However, flotation of fine particles, especially phosphate ores, has always been one of the fundamental problems. For example, about 10% of Esfordi phosphate processing plant ore with a grade of more than 16% P2O5 and d80 of less than 30 μm is sent to the tailing dam.

the successful flotation of apatite from the pyroxenite when alkalis are used depends on the use of softened water, and/ or the heating of the water to at least 35-40 C. to maintain a pulp temperatre in this region. While the amounts of fatty acids and alkalis for a given sample can be tested and regulated for optimum results of flotation, it is still found that a pyroxenite sample …

In general, apatite is the most significantphosphate ore extracted. Lately, apatite has also become a topic of interest for rare earth element (REE) recovery (Owens et al., 2019; Sun et al., 2015; Wu et al., 2018). With the growing demand for this mineral and the decreasing or challenging supply, processing tailings from an Iron Oxide Apatite (IOA)
