magnetic pyrites
RareTechnical/Scientific
Definition
Meaning
A bronze-yellow mineral, pyrrhotite, which is magnetic and is a sulfide of iron.
An ore of iron that exhibits natural magnetism and is often a source of iron and sulfur in mining contexts.
Linguistics
Semantic Notes
The term is predominantly used in mineralogy, geology, and mining. 'Magnetic' refers to its physical property; 'pyrites' links it to the broader 'fool's gold' mineral family, though it is distinct from pyrite (FeS2).
Dialectal Variation
British vs American Usage
Differences
No significant difference in usage; both variants use the term within technical literature.
Connotations
Conveys a strictly scientific, descriptive mineralogical term in both varieties.
Frequency
Extremely low frequency in general language; confined to specialist texts in both regions.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'магнитный пирит' without context, as 'пирит' typically refers to non-magnetic pyrite. The precise Russian term is 'пирротин' or 'магнитный колчедан'.
Common Mistakes
- Confusing it with non-magnetic pyrite (FeS2).
- Using 'magnetic pyrite' as a singular noun; it is typically plural ('pyrites') in this compound term.
- Misspelling as 'magnetics pyrites'.

FAQ
Frequently Asked Questions
No. Fool's gold is typically pyrite (FeS2), which is not magnetic. Magnetic pyrites is pyrrhotite (Fe1-xS), which is magnetic.
While sometimes seen, the standard compound term in mineralogy is the plural 'magnetic pyrites'. Using the singular 'pyrite' can cause confusion with the non-magnetic mineral.
It is primarily mined as a source of iron and sulfur. It's rarely an economic source of iron on its own but can be processed alongside other ores.
Pyrrhotite is fairly common globally, but the specific term 'magnetic pyrites' is a technical descriptor used infrequently outside of geological contexts.
