Flotation level measurement techniques explained April

Flotation Level Measurement Techniques Explained April

Probably the most common, although not ideal, method of measuring level in a flotation cell is via a combination of an ultrasonic level transmitter and a target plate assembly. This technique involves connecting a target plate to a float and then measuring the changes in height of the target plate using an ultrasonic instrument.


Further Developments In The Control Of Level

Interface level in flotation columns is generally measured with the aid of a pressure-sensitive instrument ego a differential pressure cell or Metritape. The use of this type of measurement is critisised, and other methods which are claimed to give more accurate measures of interface level are discussed.

Froth flotation is a surface chemistry-based unit operation that involves the capture of hydrophobic particles by air bubbles in aqueous slurry, followed by levitation and collection in a froth layer. Conversely, because hydrophilic particles do not adhere to air bubbles, they are likely to sink and go to the underflow of the flotation cell 3.
