Sensory deprivation

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, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heatsense), and the ability to know which way is down.

Two of the restrictions of the existing flotation plant at Dorfner were its low throughput capacity and the need of a cleaning stage to produce a saleable grade of concentrate. The use . of amines to float fine particles results in a very stable froth. This causes significant problems with froth handling and pumping of the rougher concentrate to the cleaner flotation cells.
