A Flotation Method for Extracting Collembola from

Flotation methods for separating small animals from mineral soils have been described by Ladell (1936), Salt & Hollick (1944), Raw (1955) and Satchell & Nelson (1962). These methods are based on the principle that organic materials float in solutions of specific gravity 1 20, whereas mineral matter sinks. Clearly these methods are not suitable

Flotation - an overview | ScienceDirect Topics

Flotation is widely used to separate valuable minerals from the rock and fine coal particles from clay, silt, shale and other ash-producing matter. It is usually preceded by crushing and grinding the ore to liberate valuable particles in a host rock, and may be followed by metallurgical processes.
