Mar 26 2016 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.
What is Chromite Chromite is an oxide mineral composed of chromium iron and oxygen FeCr 2 O 4.It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.
