Some crude differentiation occurs, probably due to gravity separation.
2.
However, many refineries now use plastic parallel plate packing to enhance the gravity separation.
3.
Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
4.
Gravity separation is also called relative gravity separation as it separates particles due to their relative response to a driving force.
5.
Gravity separation is also called relative gravity separation as it separates particles due to their relative response to a driving force.
6.
Of the gravity separation processes, the spiral concentrators and circular jigs are two of the most economical due to their simplicity and use of space.
7.
The API separator is a gravity separation device designed by using Stokes Law to define the rise velocity of oil droplets based on their density and size.
8.
In geology, a "'placer deposit "'or "'placer "'is an accumulation of valuable minerals formed by gravity separation during sedimentary processes.
9.
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching.
10.
When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separation circuit where the density of the metal is used to liberate it from the lighter silicate minerals.
