3.2 Gravity separation process. The density of chromite ore is slightly higher than that of its other magnetic gangue ore. Therefore, the separation of ferrochromium from other minerals can be realized by gravity separation. Use spiral chute to separate the concentrate process tailings and the scavenging process concentrate respectively.

Rhyolite; Rhyolite is felsic igneous extrusive rock and it is a fine-grained and dominated by quartz (>20%) and alkali feldspar (>35%).Due to the high silica content, rhyolite lava is very viscous.It is often difficult to identify rhyolites without chemical analysis due to their glassy groundmasses. Many rhyolites consist mainly of glass, and are termed obsidian, or are partially devitrified ...

Sep 01, 1987018332Weathered biotite was quantitatively isolated using a new liquid magnetic separation technique, from sand fractions of soils without any chemical pretreatments. Most of the grains in sands 1002000 m were associated with low specific gravity lt 2.70 fractions.

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al. 1996) and crushing and jigging (Khan et al. 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 1 mm and −1 mm fractions.
