— In this review, a series of meaningful explorations of magnetic technologies for the separation of natural products and biologic objects, including magnetic ionic liquids and other magnetic solvents and fluids, magnetic nanoparticles and magnetic fields, and the development of magnetic separators were reviewed.

 — High gradient magnetic separation technology is a green production technology that has an unparalleled superiority in separating fine and weak magnetic particles.

 — 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.

 — The field of magnetic separation technology is continuously evolving. Recent advancements include the development of high-gradient magnetic separators (HGMS). These devices generate exceptionally high magnetic field gradients, thereby significantly increasing separation efficiency.

 — The development of magnetic separation technology using magnetic nanoparticles offers a promising avenue for targeted drug delivery and dealing with the upcoming water crises, environmental pollution and the gradual mineral resource depletion.

Magnetic separation is a process where a contaminant is first attached onto a magnetic carrier material (e.g., magnetite), and subsequently, the contaminant-laden carrier is separated under a magnetic field. The simplest magnetic separator is a permanent magnet.

 — Magnetic separation has become increasingly popular in biomedical science and industry. This technology uses magnetic properties of micro/nano-sized particles to separate macromolecules of...

 — Magnetic separation technology is a physical separation method that uses the differences in magnetism between matter to separate them from each other by different motion behaviors in a non-uniform magnetic field.

 — Numerous technological milestones and key drivers of innovations in magnetic separation have resulted in a wide range of magnetic techniques that are available for application in various industries. This paper reviews the current status of magnetic separation and outlines the future trends in research and development.
