Flotation column automation: state of the art
A review of the trends and state of art in automation and control of flotation columns is presented. Besides the large number of columns installed in concentrators world-wide, there are a number of unsolved problems related to lack of instrumentation, lack of process knowledge, odd operating practices, and in general, lack of management and data processing.

A study of axial backmixing in a 0.76-m flotation column
The liquid-phase mixing within CAN MET's Western Research Centre's (WRC) 0.76-m-diam pilot-plant flotation column was characterized using a salt tracer. The process variables studied were frother addition and gas and liquid flow rates. The response of the column to a tracer pulse was monitored at three axial and two radial locations. The results showed that …

Kinetic studies in flotation columns: Bubble size effect
The collection first order rate constant of a flotation column was investigated as a function of bubble size within ranges commonly seen in industrial column flotation practice. The experimental work was done in a 2.5 cm diameter glass column. High purity minerals (silica, pyrite and galena) were used for the test work.
