Study of efficiency of organic activator application to process difficult-to-beneficiate polymetallic ridder ores
The article presents the results of flotation beneficiation experiments for polymetallic ore of complex mineralogical composition with the use of alkylbenzenesulfonic acid (ABSA) as a frothing reagent. Additional experiments showed the highest efficiency of ABSA application for samples of mixed-type ores, showing a significant increase in the recovery of gold, copper, zinc, and lead in the collective concentrates of flotation beneficiation. The use of an ABSA activator promotes the additional cleaning of fragments containing valuable metals from oxide films and coatings, as well as the transfer of microparticles of valuable metals due to the adsorption properties of organics and the formation of metal–carbon bonds. Another effect of this reagent use is an increase in the mass yield of concentrate while maintaining the quality parameters. Gold recovery in the main collective flotation concentrate more than doubled from 46.81 to 97.06%; copper recovery increased from 67.5 to 90.8%, zinc from 22.04 to 58.81%; and lead from 51.13 to 81.1% during the beneficiation process of polymetallic ore with the use of ABSA. A similar effect was observed for beneficiation of copper ore with complex composition; copper recovery in the main concentrate increased from 33.57 to 87.61%. Selective flotation with the development of gold concentrate from difficult-to-beneficiate polymetallic ore also showed a significant increase in gold recovery from 60.41 to 90.24% with ABSA pretreatment.
期刊介绍：
Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc.
Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
