Special Issue Information

Dear Colleagues,

This Special Issue aims to gather contributions from those who have developed sound solutions for problems posed by the industry, making use of practical approaches such as process mineralogy, enhanced sampling, data analysis and modelling, and mine-to-mill integrated solutions, as well as improvements in plant performance via new reagents, equipment, instrumentation, and/or control. The approach to many specific problems in mineral processing commonly starts in the laboratory and is primarily governed by fundamental physical and chemical laws whose effect is reasonably predicted when applied to relatively pure minerals studied under ideal conditions. Although such an approach has promoted considerable progress in our understanding of mechanisms and even provoked insights which may have led to innovations, a strong empiricism supports mineral processing conducted on an industrial scale. In fact, practitioners work with plants that usually process hundreds of tons per hour of ores, using recycled water instead of pure water, making use of the statistical appraisal of routine sampling information to manage daily process control and continuously adjusting process variables to adapt the operating equipment to variations in mass pull, ore texture, and composition. Those professionals certainly have relevant experience on how to deal with revenant problems frequently found around the world. Because the Guest Editors of this Special Issue firmly believe that the synergism between ideal and real approaches plays a pivotal role in the expansion of knowledge, both researchers and practitioners are highly encouraged to share their experience with the mineral processing community on how to approach and solve practical problems posed by the mineral industry. The first edition addressed most of the aspects related to progress in bridging the fundamental mechanisms involved in mineral processing to the operation of industrial plants. The gap is narrowed by the increasing substitution of empirical practice by engineering-oriented approach for improving plant performance. The second edition of the Special Issue of the Process Mineralogy, Plant Practice and Developments in Mineral Processing aims to include developments in aspects such as advanced characterization of critical minerals, increasing the efficiency in comminution equipment and circuits, advanced mathematical modelling, innovative mineral processing flowsheets, updated process control, fundamental and applied knowledge in flotation, solid-liquid separation process and equipment for tailings disposal, reprocessing of plant tailings, characterization and processing of minerals for energy transition and circular mining.

This study investigates the feasibility of using a triboelectrostatic belt separator (TBS) as a dry alternative to conventional magnetic separation for concentrating apatite from a phyllosilicate-rich phosphate ore from the Unidade de Mineração de Angico, Brazil. The testing material contained 22.9% P2O5 and exhibited over 90% mineral liberation even at coarse fractions (+0.6 mm), being mainly composed of apatite and Mg/Al-bearing phyllosilicates. Pilot-scale experiments were carried out in an M6c TBS, evaluating operational parameters such as electrode polarity, belt speed, feed rate, and electrode gap. In the rougher stage, apatite’s positive charging behavior enabled separation from negatively charged gangue, with optimal conditions (run 4) producing a concentrate of 25.3% P2O5 at 85.1% recovery. Cleaner experiments further upgraded product quality, with runs 15 and 18 yielding concentrates of 29.0% and 28.9% P2O5 and overall P2O5 recoveries of 69.3% and 74.5%, respectively. Compared to high-intensity magnetic separation currently applied at the industrial plant, the TBS achieved superior mass and P2O5 recoveries and more effective MgO removal, although Fe2O3 and Al2O3 contents remained slightly above market thresholds. These results confirm the technical feasibility of triboelectrostatic separation for phosphate beneficiation, offering environmental benefits through reduced water consumption and tailings generation. Further research should focus on finer particle sizes (−0.3 mm), electrode design, and surface charge modifiers to enhance industrial performance. Full article
