Flotation Process an overview ScienceDirect Topics

06/08/2010· The flotation process depends on several design and operational variables. We consider a superstructure that includes the following three flotation stages: the rougher, which processes the feed the cleaner, which generates the final concentrate and the scavenger, which generates the final tailing, as shown in Fig. 1.This is a simple superstructure but is used here as an example.

Sensory deprivation

Sensory deprivation or perceptual isolation is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, whileplex devices can also cut off the sense of smell, touch, taste, thermoception heat sense, and the 'feeling' of gravity.Sensory deprivation has been used in various
