Role of frother on bubble production and behaviour in ...

01-11-2008  The addition of frother is nearly universal in mineral flotation plants. Among the exceptions are operations where high salt levels in the process water can replace the two prime functions of the frother, namely to act in concert with the gas dispersion device to control (reduce) bubble size, and to provide froth-building capacity.

Mineral Processing Froth Flotation

Froth Flotation is a mineral processing process achieving solid-solid separation by taking profit of the chemical attribute leading to the possibility of selectively controlling the relative surface hydrophobicities of the various components mixed in an aqueous medium. Froth flotation is the most common industrial process based on this approach. The term surface hydrophobicity refers to the ...

Some observations are described, including: frother (MIBC) concentration evolution down a bank, frother distribution between pulp and froth phases, and loss of frother over time due to adsorption on certain minerals. A possible interference with a fuel oil addition was overcome. MIBC in recycle water was also measured.
