2004-4-5  The magnetic method exploits small variations in magnetic mineralogy (magnetic iron and iron-titanium oxide minerals, including magnetite, titanomagnetite, titanomaghemite, and titanohematite, and some iron sulfide minerals, including pyrrhotite and greigite) among rocks. Measurements are made using fluxgate, proton-precession,

Metallurgical Testing for Iron Ore

• Magnetic and Electrostatic Separation A full range of magnetic separators is available for iron ore testing, from low intensity drum separators to high gradient/high intensity separators, and for either wet or dry feeds. • Flotation Reverse flotation is commonly used to remove silica and/or phosphate from hematite-magnetite ores.
