81· In the recent past, iron ore resources from Brazil consisted of relatively high-grade iron ore, commonly processed via multi-stage crushing/screening, gravimetric concentration, magnetic separation, and reverse flotation. However, the high-grade iron ore reserves are in decline, resulting in the need to process the lower grade itabirite iron ores.

Gravity separation of two minerals, with different specific gravity, is carried out by their relative movement is response to force of gravity and one or more other forces. Normally one of the forces is the resistance to motion by a viscous fluid e.g. water. So, besides the specific gravity the factors like size, shape and weight of the particles affect the relative movement and hence the

Wet beneficiation of iron ore fines less than 1 mm typically involves a desliming stage ahead of the fine gravity separation such as spirals. The desliming is achieved using a bank of cyclones. The reject ultra-fines emerge in the overflow stream at relatively low pulp density, contain high proportions of low-value slimes, but also well-liberated iron ore ultra-fines below 0.045 mm in …

Mineral Technologies (MT) worked with a prominent Australian iron ore producer over five years to implement an innovative gravity separation technology for the beneficiation of ultrafine magnetite. The magnetite mineralisation requires a liberation size of <40 μm and selective rejection of ultrafine silica prior to magnetic separation.

121· This paper is concerned with the gravity concentration and classification of particles in a medium of water, involving particles typically finer than 1.0 mm. One of the greatest challenges is in delivering large scale, highly efficient, desliming at ∼10 μm to overcome the effects of viscosity, and in turn maximize the value of the resource.
