no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator

Application of a life cycle assessment to compare

Flotation cells are fed with raw coal slurry originating from the de-sliming process in the CHPP, where raw coal particles smaller than 0.1 mm are separated. Two types of chemicals are utilized to separate coal from its impurities: methyl isobutyl carbinol (MIBC) as a frother and diesel oil as a collector

Nov 01, 2008 PT Freeport Indonesia (PTFI) uses an adapted machine vision based control system in the rougher flotation circuit. PTFI uses VisioFroth, a machine vision system developed by Metso Minerals. Cameras in individual rougher cells measure froth velocity to determine the mass-pull; based on the measured velocity, process controls then adjust froth

How Froth Flotation Works

How Froth Flotation Works

Froth Flotation Charles Kubach, Mine-Engineer.Com The process of froth flotation is generally described as a physical-chemical action, where a mineral particle is attracted to, and attaches itself to the surface of a bubble, and is transported to the surface of a cell, where it overflows into a discharge launder, usually with the assistance of paddles, rotating in the direction of the launder
