Pyrite crystal has an extremely high iron content, which means it is naturally magnetic and would indeed stick to a magnet within close proximity. There is always the possibility of encountering weaker forms of pyrite that did not form with enough iron inclusions to offer magnetic ability, however this is extremely rare.Web

Pyrite Physical Properties. Pyrite, also known as iron pyrite or fool's gold, belongs to the mineral group sulfides. It has a metallic luster and is brassy yellow in color, often appearing with striations or cubic shapes. Pyrite has a hardness of 6-6.5 on the Mohs scale, making it relatively hard compared to other minerals.Web

Pyrite could reduce the oxygen potential during the chemical reaction with CSFD, reacting with sulfates in CSFD to convert into sulfides and magnetic iron oxide (Fe 3 O 4) simultaneously, and Bi 2 O 3 would be transformed into metallic Bi. These findings are significant for developing arsenic-containing hazardous waste treatment routes and the ...Web

Iron pyrite will stick to the magnet because of its high iron content; gold will not. You can also use a drop of nitric acid to test your specimen. (Caution is advised.) Nitric acid will turn iron pyrite black, but gold will remain the same color. To complicate things even further, pyrite and gold are often found in the same locations.Web

Pyrite roasting leads to magnetic sulfide (e.g., pyrrhotite, F e 1-x S, 0 ≤ x ≤ 0.125) and iron oxide (e.g., Fe 3 O 4 and Fe 2 O 3) formation (Huffman et al., 1989). The conversion of pyrite into magnetic sulfides can be realized by a short roast in air through a chemical change similar to Equation (3) .Web
