Currently, the processing of beige and black phosphates only concerns the main sub-layers, while the other sub-layers (lower and upper for beige phosphate and the upper for black phosphate) are considered waste rock and stored near the complex. Therefore, the object of this research is the use of mixtures of three beige phosphate sub-layers and two black phosphate sub-layers as a feed fraction for the calcination and reverses flotation processes. This research work aims to characterise and treat two types of phosphate: one beige with the sub-layers (main, lower and upper) and the other black with the sub-layers (main and upper) in order to have better recovery of P2O5. The working methodology consists of a series of sample preparation operations and characterization of the two types of beige and black phosphate. This characterization includes a petrographic study, a granulochemical analysis, an X-ray diffraction (XRD), a scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS), and an atomic adsorption spectrophotometry (SAA), an auto analyzer (AA), a Bernard calcimeter. These analyzes allow on the one hand to identify the mineral phases in quantitative and qualitative manner, and on the other hand to choose the process for treating phosphates from the Kef Essenoun–Tebessa deposit. The combined method of treatment by calcination followed by reverse flotation gave satisfactory results. The P2O5 content reaches 33.88 % for beige phosphate and 33.13 % for black phosphate. The stored waste rock represents a problem for the company; this waste rock contains fairly high levels of phosphate. The treatment of the mixture of the main sub-layers with these waste rocks makes it possible to obtain a better recovery of P2O5, a better economic profitability of the Djebel Onk mining complex and an environmental impact in the region.

“…With the global demand for apatite, which is a non-renewable mineral resource, phosphate ores are being depleted and their composition is changing. In addition, an increase in the alkalinity of recycled water causes a change in the composition of sorption mixtures used as reagents in the floatation enrichment method. − …”

Interaction Features of Sodium Oleate and Oxyethylated Phosphoric Acid Esters with the Apatite Surface

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 of which depends on complex heterogeneous processes occurring at the boundary of three phases (“liquid–gas”, “solid–liquid”, and “solid–gas”). Significant influence on the process have the flotation modes and composition of the reagent mixture, which provide a synergistic effect. The purpose of this work was to investigate the reasons for the synergism of surfactants used in apatite ore flotation with fatty acid-based collectors. The object of the study is a monomineral fraction of apatite, separated from the apatite-nepheline ore of Khibiny deposits. In the course of the work, it was found that the mixture of sodium oleate and phospholane PE65 has a synergistic effect on the mineral surface of apatite during foam flotation. The ratio of reagents was determined at which the maximum synergistic effect was observed.

“…Such laboratory tests consume much labor and need special and expensive equipment. Despite the labor intensity, these tests yet remain irreplaceable in modeling, design and upgrade of concentration factories for ferrous metal ore [20,21], nonferrous metals [22][23][24][25][26][27], noble metals [28,29] and nonmetallic minerals [30,31].…”

The paper addresses determination of ore hardness and grindability parameters using the data obtained from the industrial comminutions circuits survey campaigns. The calculations use the earlier obtained relations between the high-energy impact fracture parameters A and b from JK DWT and SMC tests and the energy efficiency indices used in the Morrell method for the conventional grinding, coarse grinding and high pressure grinding roll milling. Using the simulation modeling of comminution circuits for two types of sulfide copper-nickel ore and one type of apatite-nepheline ore, it is shown that the relative error of the theoretical determination of the JK DWT and SMC testing data is never higher than 16.1%. The calculation method is recommended for application in design and optimization studies of process plants for various genesis minerals, including iron ore.
