Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. As the term is used by geologists, sand particles range in diameter from 0.0625mm (or Template:Fraction mm, or 62.5 micrometers) to 2 millimeters. An individual particle in this range size is termed a sand grain.

Black sand concentrates are what you end up with after first processing of your gold bearing material. It is usually a combination of minerals in the iron group: Hematite, Fe3o3, with a specific gravity of 5.26, an iron mineral that is non-magnetic and Magnetite, Fe3o4, with a specific gravity of 5.20, is magnetic.
These mineral sands are in placer deposits which have been naturally concentrated by gravity. They have been mined since 1934 and Australia has a major share of the world market for both titanium minerals and zircon. In the mining plant they are concentrated by gravity (in spiral sluices) and magnetically (for ilmenite).
The mineral separation plant commenced operation in 1977. Heavy mineral concentrates (HMC) from the mining plants were treated on wet high intensity magnets (WHIMS) to recover ilmenite for the smelting process. The non-magnetic fraction, containing rutile, zircon, quartz and other unwanted minerals was fed to a gravity circuit consisting of primary
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. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

The specific gravity of a mineral determines how heavy it is by its relative weight to water. The specific gravity value is expressed upon how much greater the weight of the mineral is to an equal amount of water. Water has a specific gravity of 1.0. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water.
May 16, 2018· After silica sand gravity separation, there will still some percentage magnetic minerals in silica sand, so need to remove it by magnetic separator, different magnetic minerals, will use different gauss magnetic separator, for removing iron, need 1000 gauss, for removing ilmenite and hematite, need 8000-9000 gauss. Different usage of silica ...
Gravity Separation. Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation, and is normally a wet process although examples of dry gravity separators exist. Gravity separation works best when there is a large difference in the SG in the minerals to be separated, and the particle size is ...
