LST Diamond Gravity Liquid Imported from AustraliaIn the mineral industry, laboratories typically use heavy liquids to separate "light" minerals (such as quartz and clay) from "heavy" minerals. The density used for this type of separation is about 2.85 g/mL, almost three times the density of water. Another use of heavy liquids is in paleontology. Usually, these heavy liquid separations are carried out at lower densities (such as 2.2 g/mL) because the separation is not between different types of minerals, but between fossil bones and minerals, with a specific gravity of 3.32 and a natural diamond specific gravity of 3.52. Natural diamonds will sink in the specific gravity liquid, providing reference because any gemstone with a specific gravity exceeding 3.3 will sink in the specific gravity liquid. Heavy liquids are dense fluids or solutions.
Viscosity of LST heavy liquid:
Low viscosity is a characteristic of LST heavy liquid. The grain separation speed in LST heavy liquid is roughly the same as that when using TBE, but there is no occupational health risk associated with organic halides. The exact viscosity of LST heavy liquid will vary with temperature and density (see Figure 3), typically around 11 cP.

Thermal stability of LST heavy liquid:
LST heavy liquid remained at a temperature of 140 ° C for more than two weeks without significant changes. The high thermal stability of LST heavy liquid allows it to boil to evaporate water and restore its original high density. The stability of LST heavy liquid means that recovery is fast, simple, and effective.
LST Diamond Gravity Liquid Imported from AustraliaUsed to separate materials of different densities through their buoyancy. Materials with a density greater than that of heavy liquids will sink, while materials with a density less than that of heavy liquids will float on the surface of the liquid. Another use of heavy liquids is in paleontology. Usually, these heavy liquid separations are carried out at lower densities (such as 2.2 g/mL) because the separation is not between different types of minerals, but between fossil bones and minerals. LST solids contain highly soluble, colorless hydrated crystal forms of lithium heteropolytungstate. The concentrated aqueous solution of LST forms a colorless or light yellow heavy liquid. LST heavy liquid is usually used together with aqueous bases. However, LST crystals are also highly soluble in acetone and alcohols, and can form dense liquids in these organic solvents. This provides a series of methods for using and recovering LST heavy liquid.
