Special Issue of PPMP Journal in honor of Prof. Juan Yianatos

The special issue of Physicochemical Problems of Mineral Processing (PPMP) will be dedicated to honouring Professor Juan Yianatos, an outstanding scientist, friend, and mentor.

Professor Yianatos is currently a Faculty member in the Department of Chemical and Environmental Engineering at Universidad Técnica Federico Santa María, Chile. His areas of interests include metallurgical and hydrodynamic characterizations of industrial flotation circuits, highlighting his contributions on gas dispersion measurements, estimation of residence time distributions, simulation of flotation processes, kinetic modelling, and scale-up strategies from laboratory results to large-scale machines. He has stood out by his applied research, with vast collaborations with engineering and mining companies such as Nuclear Trace and Engineering, Metso-Outotec, BHP Billiton, Codelco-Chile, Anglo American, Glencore, Antofagasta Minerals, just to name a few. He is currently leading a research project on new methodologies to improve the scale-up and design of industrial flotation circuits.

Professor Yianatos has been a member of several editorial boards, Chair of the XXVII International Mineral Processing Congress, and a member of the IMPC Council (2010-2021). Apart from being awarded for his contributions to industrial applications, he has recently been listed in the World’s Top 2% scientists by his productivity, and impact and quality of his research in the area based on the Stanford University Ranking

To honour the 40 years of scientific work of Professor Yianatos, the topics of interest in this special issue include;
o Challenges and opportunities in recovering fine and ultrafine particles
o Impact of entrainment and entrapment in flotation systems
o Gas dispersion characterizations and its role in the metallurgical responses
o Residence time distribution measurements and modelling in conventional flotation cells
o Characterizations, measurements, and modelling of collection and froth zones
o Flotation kinetics and thermodynamic aspects
o Hydrodynamic and metallurgical properties of industrial flotation systems
o Circuit design and scale-up from laboratory flotation tests
o Fundamental aspects of particle-bubble interactions in froth flotation
o Modelling and simulation of flotation processes
o Application of instrumentation, process control, and automation in flotation systems
o Challenges and opportunities in recovering coarse particles in flotation
o Impact of ore mineralogy on flotation performances

The submitted papers, written in English, should only contain original works, which have not been previously published (or being under consideration for publication elsewhere). In the case of material that has been already presented at a conference and published in conference proceedings, it should be extended by at least 30% of the new technical/experimental contribution. Authors of such contributions are requested to attach to their special issue submission the original already published article, and to summarize the new contribution/additions in the special issue submission.
