Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.

Veterinary Advice Online - Fecal Flotation. A fecal flotation test, otherwise known as a 'fecal float', egg flotation or Fecalyzer Test (Fecalyzer, also spelled Fecalyser, being the most commonly used in-house commercial product) is a diagnostic test commonly performed in-house in most veterinary clinics as a way of diagnosing parasitism in animals.

Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ...
