Sulfur And Copper After Grinding

What is formed if a mixture of powdered iron and sulphur

A compound results from a chemical reaction between components forming a new substance For example you can combine iron filings with sulfur to form a mixture All it takes is a magnet to separate the iron from the sulfur On the other hand if you heat the iron and sulfur you form iron sulfide which is a compound F e S →F eS.
