US Patent for Heavy liquids for use in separation processes Patent

The subject invention pertains to the use of nontoxic heavy liquids and slurries in the separation of components of ores concentrates residues soils and scrap. Specifically exemplified herein is the use of cesium and/or rubidium salts in separation processes. These salts are particularly advantageous because of their high specific gravity and solubility in water and their low solution

Use of heavy liquid density separation to remove pyrite from sediment

The use of heavy liquid in environmental and geological research dates back to at least the early 20th century (Strutt 1906). In the late 1980s and 1990s new and nontoxic heavy liquids such as sodium polytungstate and lithium heteropolytungstate have become available (Munsterman and Kerstholt 1996 Patrick and Patrick 1997). Most commonly
