Frother Analysis - Procedure and Plant Experience

A colourimetric technique, originally developed for methyl iso butyl carbinol (MIBC) based on the Komarowsky reaction, has been extended to a wide range of common mineral flotation frothers. The procedure, which is briefly described, is shown suited to on-site determinations in a campaign at Kennecott Utah Copper Copperton Concentrator (Rio Tinto). 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.
The ability to monitor frother easily will help interpret gas dispersion behaviour and should permit further optimisation of flotation cell hydrodynamics and chemistry. The capability to directly measure should help optimise the type, amount and location of frother addition, and to assess frother recycled with reclaim process water.
