Dear Colleagues,

Magnetic separation, thanks to its advantages of large processing capacity, low operation cost, high efficiency and applicability, and environmental friendliness in comparison to other separation methods, can be widely considered for use in the field of mineral processing. In recent decades, it has become one of the key separation technologies in the utilization of the ores that contain magnetic minerals, such as iron oxides, ilmenite, wolframite, and manganese, and in the removal of magnetic impurities form non-metallic ores such as kaolin, quartz, and feldspar. In addition, the development of high magnetic intensity (reaching as high as 1.8 T) high-gradient magnetic separators has been achieved, with which it is feasible to economically separate non-ferrous minerals (e.g., copper-molybdenum, copper-lead, copper-zinc separation). During this period, several magnetic separation technologies have been significantly developed from theoretical exploration to successful industrial application; as a result, magnetic separation has been attracting worldwide interest from both academia and industry. With the increasing decline in ore quality and the increasing demand for high-quality raw materials, such magnetic separation technologies with higher separation performance are inevitably required by industry, and they include the scaling-up of current magnetic separators to meet the demand for larger-scale and lower-cost exploitation of low-grade ores, higher magnetic induction for the recovery of finer magnetic minerals, for the more effective purification of non-metallic ores, innovations required for the development of new high-gradient magnetic separators, as well as extended applications in various processing flowsheets and for minerals previously thought impossible to be magnetically separated, etc.

This Special Issue is intended to collect the latest findings in the aspects of magnetic separation discussed above.

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. Magnetochemistry 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 2700 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.
