Abstract
The invention discloses a measurement apparatus for measuring a volume of a desired solid component in a sample volume of a solid-liquid slurry. The sample volume of the slurry is received into a receptacle and screened to separate out the desired solid component from a remainder of the slurry, whereby the solid component is retained in the receptacle to form a bed therein and the remainder is exhausted. The height of the bed is subsequently measured by a laser being adapted to emit a laser beam into the receptacle, thereby enabling a determination of a volume and/or mass of the solid component retained in the receptacle. The invention further discloses a control system for a leaching plant utilising the measurement apparatus.
