IHC Jigs Versus Other Gravity Separators

• Gravity separators
• Thick-bed versus thin-bed separators
• Spiral
• Sluice box
• Conventional jigs and the IHC Jig

It is astonishing how wide a variety of machinery is being offered for gravity separation .This started with ground sluices and later developed into numerous
devices, each claiming to be the answer to a particular separation problem. For wet gravity concentrators, the applicability of the most common types pertaining
to the particle size range is indicated in Fig. 1.

For the normal alluvial deposits (also referred to as placers) with the valuable
minerals (gold, cassiterite, monazite, rutile, etc.) at a size range of 0.05 to 5 mm, the thick and thin bed separators should be considered for the beneficiation process.
