Abstract
A froth bubble moving speed measuring device includes a light source configured to illuminate an upper surface of a flotation tank, an imaging unit configured to capture at least a part of the upper surface of the flotation tank, and an arithmetic processing unit configured to calculate a moving speed of a froth bubble by calculating a moving distance of the froth bubble based on the image processed by the image processing unit.
