Fine-grained low-grade manganese ore is difficult to extract due to some mineral processing technology problems, such as non-selective aggregation between ore particles, large dosage of flotation reagents, and low efficiency of flotation. In recent years, multiple types of collectors have been used for the flotation of low grade manganese ore (less than 13%), while …
Floatability of pyrolusite from an Iranian low grade manganese ore (13.6% MnO) containing calcite as the main gangue mineral was investigated with Armac C as a cationic collector. In the single mineral flotation experiments, the maximum recovery of pyrolusite is obtained at 82.2%, using 2000 g/t Armac C at a pH of 9, while at these conditions the flotation …

In Brazil, the first application of amide-amine applied to flotation was reported by Souza et al., 2015, Souza et al., 2016 where the authors used this collector for kaolinite flotation from a manganese ore. The process was composed of desliming (−10 µm), followed by reverse cationic flotation of kaolinite (rougher, scavenger) at pH ~ 5.

Hence, this work studied the effect of sodium oleate concentration variation on the froth flotation of manganese ore obtained from Madaka, Niger State, Nigeria. The chemical analysis of the ore shows that it contains 48.4% MnO (37.5% Mn). ... Laskowski, J., Vurdela, R.M. and Liu, Q. (1998) The Colloid Chemistry of Weak Electrolyte Collector ...
The design and development of selective flotation collectors has been the key to the remarkable success of flotation in beneficiating complex, difficult-to-process ores.
ore, we can provide collectors for the slime flotation step needed prior to potash flotation. We also offer collectors for reverse flotation where halite is floated to beneficiate carnallite. Rely on our 80-years of expertise as the world-leading supplier of collectors to the potash industry to enhance flotation efficiency. Case description

However, in bench tests carried out with manganese ore fraction sizes between 43 and 106 µm, no selectivity be-tween the manganese and gangue minerals was ob-served. Lima et al. (2008) performed bench flotation studies, at pH 11 by using sodium oleate as a collector and water glass as a depressant, of silicate-carbonate manganese

the flotation response of rhodochrosite was only slightly affected at both pH 9 and pH 11. Development of linoeate hydroxamic acid to float a low-grade manganese ore was carried out by [5]. The performance of this LHA and oleic acid (OA) used for anionic froth flotation was compared, and the critical factors of rhodochro-
A theoretical analysis was conducted to study the role of collectors and depressants in flotation, based on the extended Derjaguin–Landau–Verwey–Overbeek (DLVO) theory, where the hydrophobic force is considered. The collector-coated hydrophilic particle and the depressant-coated hydrophobic particle are simplified to a sphere uniformly covered with …
