Flotation Method in Archaeology

Flotation Method in Archaeology

The earliest published use of water separation dates to 1905 when German Egyptologist Ludwig Wittmack used it to recover plant remains from ancient adobe brick. The widespread use of flotation in archaeology was the result of a 1968 publication by archaeologist Stuart Struever who used the technique on the recommendations of botanist Hugh

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
