Pyrrhotite an overview ScienceDirect Topics

G.W. Heyes, in Iron Ore, 2015. 11.3.2.3 Sulfur removal. Magnetite ores often contain sulfide minerals including pyrrhotite and pyrite. Most sulfide minerals are nonmagnetic and can be rejected by magnetic separation. Monoclinic pyrrhotite, however, in contrast to hexagonal pyrrhotite, is magnetic and is recovered in magnetic concentrates.

4 Extraction Processes for Gold-Pyrite Ore

In addition to pyrite, the ore may also contain a small amount of metal minerals such as galena, chalcopyrite, and pyrrhotite. Gangue minerals are mainly calcite and quartz. The content of pyrite is 20-45%, accounting for more than 90% of the total metal minerals. 2. The Extraction Processes of Gold-Pyrite Ore

How do pyrite and pyrrhotite damage building foundations

Pyrite and pyrrhotite are minerals known as iron sulfides. When iron sulfides are exposed to water and oxygen, a series of chemical reactions breaks down the iron sulfides and forms new minerals called sulfates. These sulfates take up more space than the original iron sulfides. As they grow, the new sulfate minerals push against the surrounding rock, causing it to swell and
