Comminution and classification technologies of iron ore

However, cyclone application in magnetite grinding circuits can cause inefficient operation due to the density difference between magnetite and waste minerals (silica). Magnetite has a specific density of about 5.15, while silica has a specific density of about 2.7. In hydrocyclones, dense minerals separate at a finer cut size than lighter ...

dry magnetite operations

Magnetite is an oxide of iron (as is hematite). It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny ...
