    2 Mining and concentrating. Although workable known reserves of rutile are diminishing, ilmenite deposits are abundant. Typical mining is by open pit. A suction bucket wheel on a floating dredge supplies a mineral-rich sand to a set of screens called trommels, which remove unwanted materials.

  • Gravity Spiral Concentrator Working Principle

    The processes involved in mineral concentration by spirals are similar for all models. As feed containing 25-35 solids by volume is fed into the channel, minerals immediately begin to settle and classify. Particles with the greatest specific gravity rapidly settle to the bottom of the spiral and form a slow-moving fluid film.
