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. The section should be divided into four subsections: "Sample Preparation," "Flotation of Pure Apatite," "Flotation of Apatite-Containing Tailings," and "Flotation Kinetics."

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 …
Source of Ca in the flotation tailing comes from phosphate or largely carbonate minerals like calcite and dolomite. Figure 6. XRD patterns of flotation concentrate (i.e. apatite conc.). Figure 9. SEM-EDS images of flotation tailing. 4. CONCLUSION Figure 7. SEM-EDS images of flotation concentrate (i.e. apatite conc.).
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.

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 ...
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.
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 …
The results indicated that nanobubble flotation of the as-received apatite tailings (−850 μm) was an attractive option that can minimize the CO 2 footprint of mineral processing …

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 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.
