"Of the commonly occurring metal sulfide
minerals, pyrrhotite is most often cited as an unstable and hazardous mineral in matrices as varied as coal, concrete, and massive sulfide, due to its propensity for rapid oxidation. This instability has been attributed to the
variable stoichiometry e.g. a high relative surface area, or surface roughness and extended fractures."

note the bit about "high relative surface area", like

if anyone had stopped at any point to go, "hmm, is this a good or safe idea? what does the lit say?" they would not have a paper because they wouldn't have squashed it to a fine powder 😂
