Not with an ordinary magnet alone. A magnet has been used to collect one group of chiral crystals, but only after researchers made that group magnetic-responsive using specially designed magnetic nanoparticles. The work does not show that a magnet can identify or sort the handedness of untreated crystals.
What a magnet can—and cannot—do
Some chiral substances crystallize as a conglomerate: a mixture of separate crystals, each made up of one enantiomer. The individual crystals can therefore be enantiopure even though both handed forms are present in the batch. Because the two populations can look alike, separating them by hand may be difficult.
In the method reported by Ye and coauthors, the magnet is a collection tool at the end of a chemical process. It does not detect chirality. The researchers selectively loaded one crystal population with magnetic material so it responded differently from the other population. A magnet could then pull that responsive fraction from the mixture. The 2019 Nature Communications study describes the approach.

Magnetic nano-splitters changed one crystal population
The researchers assembled magnetic nanoparticles with chiral polymeric inhibitors to create additives they called “nano-splitters.” Along with seed crystals, these additives influenced nucleation and growth so magnetic material was incorporated preferentially into crystals of one handedness. The resulting crystal populations had different physical properties.

A permanent magnet collected the responsive crystals
In the asparagine monohydrate demonstration, colorless R crystals formed first, followed by dark-brown S crystals. The dark-brown crystals contained magnetic material and were screened from the mixture with a permanent magnet. Under the study’s optimized slow-evaporation condition, the authors reported averages across three experiments of 99.2% enantiomeric excess (ee) for the R crystals, 95.0% ee for the S crystals, and 95.1% total yield. These are results for that experiment, not expected performance for an unknown crystal mixture or magnet.
The paper also reports examples involving threonine, allo-threonine, and p-hydroxyphenylglycine p-toluenesulfonate. The authors framed the strategy around conglomerate-forming systems; it is not evidence that every chiral crystal can be separated this way.

Will a magnet you already own work?
The study names a permanent magnet for collecting the finished magnetic crystals, but it does not specify a consumer magnet model, grade, distance, or required field strength for that step. It therefore cannot support a recommendation that a refrigerator magnet, neodymium magnet, or other particular magnet will work for your material.

That condition was reported for separating nano-splitter assemblies from aqueous solution, a different operation from collecting finished crystals. The paper also notes that crystals with weaker magnetic loading can be harder to collect, and that entangled, thin needle-like crystals can be difficult to screen.

How this differs from other magnetic crystallization research
Other studies investigate magnetic substrates that influence crystallization and spatial separation rather than adding magnetic nano-splitters and then collecting responsive crystals. A 2019 Chemical Science paper reports enantioselective crystallization on magnetized substrates and notes that results can depend on the compound and its crystallization behavior: Enantioseparation by crystallization using magnetic substrates. A 2021 Crystal Growth & Design paper reports a different magnetic-substrate method that, in its tested system, did not require seeding or chemical modification: Simultaneous High-Purity Enantiomeric Resolution of Conglomerates Using Magnetic Substrates.
These approaches are distinct research methods, not demonstrations that a loose magnet sorts arbitrary crystals. Their requirements and outcomes depend on the method and tested compound.
