“…Unlike the results of the Hallimond tube where direct flotation was achieved, cell flotation results were different. These contradictory findings led us to suspect other parameters that may influence flotation response as attrition, solid content Cs and desliming (Alsafasfeh et al, 2017;Kawatra et al, 2013).…”

Due to increased population growth, arable land is becoming more and more depleted. Phosphorus is then needed more than ever. Therefore the focus is brought to the possibility of returning to the deposits considered so far without interest (Cao et al. 2019;Chen et al. 2017;Dong et al. 2017;Filippov et al. 2019). Within a major project with the group OCP, this work aims at upgrading low grade phosphates. New beneficiation routes are investigated to selectively separate apatite from gangue minerals, mainly carbonates and quartz. A micro-flotation study was conducted on pure minerals of fluorapatite, calcite and quartz based on mineralogical feature of low grade Moroccan phosphates. Results showed the possibility for a direct flotation. The most potent combinations of reagents were: carboxymethylcellulose and sodium alginate when used with sodium oleate and ATRAC as collectors (Aarab et al, 2020). A scale up of these findings to the mechanical cell fail to obtain the same tendency. An asymmetrical fractional factorial design was used with, as parameters: the type of the collector and depressant, their dosage and conditioning time, flotation time, pH and desliming. Partial matrix results presented in this work confirmed the non-possibility of direct flotation under these conditions, but a reverse flotation is possible. Conclusions will be drawn once the DOE results are completed, considering the possibility of direct and reverse flotation of low grade phosphate ore.

“…En base a las consideraciones anteriores, se concluye que existe un enorme potencial económico, ambiental y social, puesto que dichos relaves pueden explotarse con el fin de aumentar el desarrollo de la región de Atacama. En ese sentido, este trabajo Ciência e Tecnologia: Desenvolvimento Ambiental, Cultural e Socioeconômico Capítulo 13 188 tiene como objetivo evaluar la recuperación de apatita contenidas en relaves de hierro; cuyo tratamiento es una alternativa rentable frente a otras, y porque su retratamiento permitiría generar un flujo de caja positivo (Alsafasfeh & Alagha 2017).…”

“…The phosphate ores mainly contain the siliceous phosphate rock, calcareous phosphate rock, and calcareous-siliceous phosphate rock. Both of the anionic direct flotation and cationic reverse flotation are applied for the beneficiation of siliceous phosphate rock, while the single anionic reverse flotation is preferred to beneficiate the calcareous phosphate rock [9][10][11][12][13][14].…”

In this study, there is 1.42% P2O5 in the P-containing V-Ti magnetite tailings in Miyi Region of China, with the valuable minerals mainly including apatite, and aluminosilicate minerals as the main gangue components. The direction flotation process was used to recover phosphorous from the low-grade phosphorous-bearing V-Ti magnetite tailings. The results showed that an optimized phosphorous concentrate with a P2O5 grade of 31.35% and P2O5 recovery of 88.02% was obtained by flotation process of one roughing, three scavengings, and three cleanings under roughing conditions, which employed pulp pH of 9, grinding fineness of <0.039 mm occupying 90%, flotation concentration of 25%, and dosages of carboxymethylcellulose, oxidized paraffin wax soap, and pine oil of 400 g/t, 300 g/t, and 20 g/t, respectively. Optimized one scavenging, two scavenging, and three scavenging conditions used a pulp pH of 9, and dosages of carboxymethylcellulose, oxidized paraffin wax soap, and pine oil of 200 g/t, 150 g/t, 10 g/t; 100 g/t, 75 g/t, and 5 g/t; and 100 g/t, 75 g/t, and 5 g/t, respectively. Optimized one cleaning, two cleaning, and three cleaning condition dosages of carboxymethylcellulose of 100 g/t, 50 g/t, and 25 g/t, respectively. Study of analysis and characterization of phosphorous concentrate by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) show that most gangue minerals enter the flotation tailings, the main minerals in phosphorous concentrate are apatite, olivine, and feldspar.
