LST Fastfloat : heavy liquid for density separations. Description and applications. LST Fastfloat consists of low toxicity sodium heteropolytungstates dissolved in water. It is a high density liquid for laboratory based density separations, supplied at a density of g/mL but capable of being used up to a density of g/mL at 25 °C. LST Fastfloat is the lowest viscosity water based

Heavy mineral suites are used to help determine the provenance and history of sedimentary rocks. As heavy minerals are a minor constituent of most sedimentary rock, they must be separated out to be studied. Heavy mineral separation generally uses a dense liquid in either a separatory funnel or centrifuge. Liquids used include bromoform

The Sink and Float separation process is part of what is also known as a Heavy Media Separation Process (HMS) and are commercial adaptations of the common laboratory procedure used for separating a mixture of two products having differentials in specific gravity by immersing the sample in a heavy liquid having a gravity intermediate to those of the products to be separated. The lighter

Heavy mineral characterization of samples arising from exploration, mining or metallurgical processes is frequently conducted using laboratory heavy liquid analysis. Unfortunately, there are only a limited number of high density (''heavy'') liquids and these tend to be more toxic as their density increases. Lowtoxicity inorganic solutions, based on tungsten compounds, have been developed

The mineral sands industry uses heavy liquid separations to check the grade of samples in their process, and to determine the efficiency of their industrial hydrocyclone separations. The diamond exploration industry uses heavy liquids to separate the dense indicator minerals from sand and clay. Another use of heavy liquids is in paleontology.

When draining the heavy minerals, close the stopcock quickly as soon as the heavy minerals are discharged so as not to loose too much LST (PDF). The more liquid there is in the separatory funnel, the easier the minerals separate. Do this several times or until no more heavy minerals settle. Add 5 drops of water to the heavy liquid and cap tightly.

Laboratory heavy liquid separations result in two components, the heavy fraction (or sinks) and the light fraction (or floats). In industry it is usually the heavy fraction of a mineral suite which contains the valuable component, and which is separated from sand (silica) and other components having a density less than g/mL. The solution density used for this type of separation is about 2

Bromoform (CHBr 3) is a brominated organic solvent, colourless liquid at room temperature, with a high refractive index, very high density, and sweet odour is similar to that of is a trihalomethane and is one of the four haloforms. Bromoform''s high density makes it ideal for separation of mineral ores by means of preferential flotation.
