LST Specific Gravity Liquid AustraliaIn the mineral industry, laboratories typically use heavy liquids to separate "light" minerals (such as quartz and clay) from "heavy" minerals. Heavy liquids are dense fluids or solutions used 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. The density used for such 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 (e.g. 2.2 g/mL) because the separation is not between different types of minerals, but between fossil bones and minerals.

There are various reasons for LST heavy liquid separation depending on the industry. The mineral sand industry uses heavy liquid separation to check the grade of samples during the process and determine the efficiency of industrial hydraulic cyclone separation. The diamond exploration industry uses heavy liquids to extract dense indicator minerals from sand

Separate from clay.

quality guarantee period:
LST heavy liquid is a stable solution of inorganic ions in water, which actually has an uncertain shelf life. In long-term experiments, LST heavy liquid stored for more than 10 years showed no signs of decomposition.

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.

Changes during refrigeration:
If under very cold conditions, crystals may appear in LST heavy liquid. When heavy liquids are heated to 40 ° C for several hours and occasionally shaken or stirred, they will dissolve again.

Recycling LST heavy liquid:
It is easy to recover LST heavy liquid from minerals by washing the separated minerals with deionized water, filtering, and then concentrating the washing solution through boiling evaporation. LST heavy liquid is not easily volatile, so it concentrates with the evaporation of water. In this way, LST heavy liquid can be recovered with an efficiency of over 99%. The overall plan for industrial laboratories is shown in Figure 4.

Through this method, the recovery rate of LST heavy liquid is very high. Typically, only 1.5 mL of LST heavy liquid mineral samples are lost per kilogram during routine use.

LST Specific Gravity Liquid AustraliaThe production is relatively hardcore in terms of technology and usability, and the recent development of this device is a low toxicity heavy liquid called LST. LST heavy liquid has low viscosity and excellent thermal stability. LST heavy liquid can be used with a density of 2.9 g/mL at room temperature

At high temperatures, a density of 3.6 g/mL can be used, and the LST solid contains highly soluble, colorless lithium heteropolytungstate in the form of hydrated crystals. 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 alcohol can form dense liquids in these organic solvents. This provides a series of methods for using and recovering LST heavy liquid.
