Special Issue Information
Dear Colleagues,
The grinding process, as a primary stage of ore/raw material processing, is a necessary operation in beneficiation plants. It not only provides the appropriate particle size for subsequent separation operations but also enables the liberation of valuable minerals from the gangue. In addition, due to the depletion of high-grade ores and the growing needs of the industry for the processing of low-grade finely dispersed ores, the development of fine/ultrafine milling processes has attracted particular attention in recent decades. The main concern in ore beneficiation and processing plants is producing the desired product size with the lowest possible energy consumption. It has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations. In addition, more than 90% of the total energy supplied in beneficiation plants is dissipated as heat, kinetic energy, noise, and inefficient breakage of ores/raw material. Therefore, any research effort that has the potential to reduce energy consumption while maximizing grinding efficiency is of great importance. This Special Issue welcomes papers that highlight innovations and future trends in modeling grinding and technological ways to improve the grinding efficiency in ore/raw material beneficiation. Emphasis is placed on mathematical modeling to accurately describe the particle size distribution of grinding products, modeling for the estimation of the energy requirements for size reduction, the simulation and optimization of the grinding process, the investigation of parameters affecting grinding efficiency, the development and design of innovative and efficient grinding equipment, and all issues that contribute to the improvement of process and energy efficiency and reduce the environmental footprint of ore beneficiation and processing plants.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
