Flotation Process of Archaeology UW-La Crosse

Flotation. To recover very small artifacts and charred seeds and nuts, soil is "floated." In this process, the soil is dried, then poured into a bucket of water. Charcoal and other plant materials are lighter than the soil, and float to the surface. They are poured off into a screen with holes of 0.5 mm, which is finer than window screening.

Flotation Techniques for the Recovery of Small-Scale

Abstract. This paper outlines the procedures and equipment necessary for applying a simple flotation technique to recover animal bone, seeds, and other small cultural remains lost in the normal screening of soils from archaeological sites. Soil is initially processed in the field by a water-separation technique.

The flotation process is governed by a complex phenomenon occurring on the surface of mineral particles and air bubbles formed in the water phase From the practical point of view the hydrophobicity and bubble mineralization are perhaps the two most important factors in flotation and govern the system kinetics and selectivity of flotation
