Can bornite scratch pyrite

Yes, bornite can scratch pyrite. Bornite has a hardness of about 3 to 3.5 on the Mohs scale, while pyrite has a hardness of about 6 to 6.5. This means that bornite is softer than pyrite, allowing it to scratch the latter. However, in practice, bornite is not typically used as a scratching tool due to its brittleness.
