Abstract
The usual focus of papers on fatty acid collector action in non-sulfide flotation is on the adsorption of the carboxylate and/or neutral molecule species at the mineral-solution interface. Little attention is paid as to whether or not the solution conditions correspond to true solutions, micellar and other self-assembly objects or precipitates. Our examination of the solution chemistry of the important fatty acid collector, oleic acid, has revealed that many, if not most investigators set their experimental conditions to be in micellar or precipitate domains while arguing, often by implication, that they have only solute species present. We have investigated the equilibrium solution domains ..
