Technical
Note Physical separation (gravity
and shape) of small-sized mica ore
To process small-sized mica contained in vein filling mined and in muscovite
dumps a separation technology has been developed. The technology is based on
gravity separation into shapes, with the behaviour of mica flakes, falling
in a liquid under different hydrodynamic regimes, taken into account. The
technology consists of separation into shapes, hydraulic separation and
table separation. Being desintegrated in a rod mill, mica booklets get
thinner and the sphericity coefficient decreases, resulting in separation
indices upgrading. The technology enables to produce a concentrate with
95-100% mica content at recovery 60-66.7% from mica contained in small-sized
ore. |
