Sinkfloat
Sinkfloat, also called sink–float analysis, is a simple laboratory method used in mineral processing and materials science to gauge the relative density of a solid sample. By placing particles in liquids of known densities, the particles will either sink or float depending on whether their density is greater or lesser than the liquid. This information helps estimate the material’s specific gravity and informs decisions about suitable separation methods, such as dense-medium or heavy-liquid separation.
Procedure commonly involves preparing small, dry pieces or crushed particles and testing them in a series of
Applications and interpretation focus on separation planning. The test helps determine an effective cut-density for separating
Limitations include variability in particle size, shape, and porosity, which can affect sinking or floating behavior.
