“…5), by the variation of the collector concentration from 0.03 to 0.30 mg/l, the Zeta potential of calcite and dolomite decreases progressively, it means the minerals surfaces become more and more hydrophobic. These conditions consequently improve the floatability of minerals (Chettibi, Boutrid, Laraba, & Abramov, 2015).…”

“…The representative samples, after being homogenized, were collected and sieved. The recommended optimum size for the flotation in the case of phosphate minerals is between 38 and 150 m (Chettibi, Boutrid, Laraba, & Abramov, 2015;Chettibi & Abramov, 2016). Thus, the size of the flotation charge used in this study was the fraction -100 + 38 μm, obtained by sieving.…”

Flotation tests have been used in order to achieve the purposes of this study which are: To obtain the highest recovery with a maximum grade of P 2 O 5 from the tailing generated by the phosphate plant of Djebel Onk in the East of Algeria. To get a good concentrate from the rejections, which gives an added value to the national economy. To preserve the human life and finally to protect the environment from the heavy metals contained in the tailings. Methods. To reach our goals we have used: the granular and XRD analysis to characterize the tailing composition so as to choose the right reagents and conduct a good flotation. Flotation tests were carried out using Sodium Oleate as a collector and alkyl hydroxamic acid (AERO 6493) as collector and frother, zeta-meter system to measure the Zeta potential of the phosphate tailing and define the convenient values insuring the particles surfaces' best adsorption.Findings. The granular analysis has allowed us to observe a main mode represented by the fraction less than 125 μm equal to 76.77%; the weight yield of the second mode of fraction (-200 + 125) μm is about 18%; the third mode represents the coarse particle size range of a mesh of greater than 200 μm represents only 4.94% in yield. However, in the case of AERO 6493, the recovery reaches 97% in condition 150 mg/l of concentrate and 26.51% grade of P 2 O 5 . On the other hand, the flotation test with the sodium oleate shows a low recovery with good content on P 2 O 5 which reaches 30%.Originality. Since the beginning of phosphate production in Djebel Onk phosphate complex in 1965, tailings have been evacuated into the nature without any further treatment. The originality of this work lays in the recovery of phosphate in the fine slice on the one hand and the elimination of heavy metals drained in the tailing on the other hand. Practical implications.Using the alkyl hydroxamic acid with different concentrations determined in the flotation tests leads to a greatest recovery of phosphate with minimum financial charges of exploitation, transport, crushing and grinding. In result, the productivity of the Djebel Onk complex can be increased and the environment can be preserved too.

“…This is due to the depression of pyrite at slurry pH values above 8 [22], therefore, limiting the recovery of gold associated with pyrite. Calcium hydroxide has also been found to depress pyrite in alkaline conditions due to the formation of iron hydroxide on the pyrite surface [23,24].…”

A pre-treatment method for upgrading gold from a polymetallic gold-zinc-lead ore by flotation was studied. X-ray diff raction analysis of the gold sulfi de ore showed that quartz, calcite, pyrite, sphalerite, and galena are the main constituents of the ore. The composition of the polymetallic ore contained 6.49 ppm Au, 3.48% Zn, 1.25% Pb, 17.98% Fe, and 20.36% S. Due to the complexity of the polymetallic ore, the gold recovery is generally low. The objective of this study is to develop a primary fl otation process to recover gold in a bulk sulfi de concentrate. The eff ects of particle size, collector type, fl otation time, and the slurry pH on the recoveries and grades of gold, zinc, and lead were investigated. The developed fl otation process consisted of rougher, scavenger, and cleaner stages. High recovery of gold was found to be linked with a high recovery of Pb which was achieved by the utilization of a mixture of collector AERO 7249 and PAX. The gold fl otation kinetics were fast with more than 50% of gold recovered within 5 minutes of fl otation. Under optimized fl otation conditions with rougher, scavenger, and cleaner stages, a total gold recovery of 88.36 % and a fi nal gold grade of 60.97 ppm were obtained. A total gold enrichment ratio of 9.4 was achieved, confi rming the viability of the fl otation method in upgrading the gold from the polymetallic sulfi de ore prior to further processing.
