Mineral Evolution ROBERT M. HAZEN

In every instance mineral evolution will occur in a progression of stages as a result of local, regional, and global selective processes. The degree to which a body will advance in mineralogical complexity beyond the relatively simple achondrite stage is dictated by the nature and intensity of subsequent cycling (and hence repeated separation and concentration of elements).

Developments in the physical separation of iron ore

The ore is composed of magnetite and gangue minerals, which are mainly quartz. The flow sheet includes three stages of grinding and magnetic separation once again to reject quartz as early as possible. Vibrating screens are again used to take out unliberated coarse quartz particles, which are returned to the ball mill for regrinding.

Mineral processing

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as heavy media, water or, less commonly, air.
