Abstract

Ion flotation is a method for the metal ions recovery from aqueous solutions. In this method, the metal ions in floating froth are recovered. In hydrometallurgical methods for extracting copper from leach solution, firstly, solution is recovered by using solvent extraction method (SX), then copper is recovered by using Electrowining method. SX is the most common method; nevertheless, there is limitation in input minimum concentration. As a result, diluted solution cannot be concentrated with this method. In this study, the use of

ion flotation method for copper recovery from a diluted leach solution from copper Mine in Qom is investigated. The Experiments were carried out on the Mine diluted solution using Denver mechanical cell types, in PH value of 6, 9 and 12 when the copper ion concentration was 10 ppm. ethanol and methyl iso-butyl carbonyl (MIBC) were used as frother. hexa decyl trimethyl ammonium bromide (HTAB) and Sodium dodesyl sulfate (SDS) were used as collector. The efficiency of this method was evaluated by measuring copper recovery. Best results were obtained at pH value of 12, by using HTAB as collector with amount of 100 ppm and 0.1% (V/V) MIBC as frother. Under these circumstances, copper recovery, have been reported 82.3%.
