frother uses in copper flotation

A Brief Review of Pulp and Froth Rheology in Mineral Flotation, For example, Cruz et al studied the effect of flotation reagents including pH modifiers (NaOH, lime, and Na 2 CO 3), collector (potassium amyl xanthate), and frother (Interfroth 6500), which are normally used in copper-gold flotation, on the rheological behaviour of kaolinite and bentonite suspensions All these reagents were found to alter ,Frothers, The commonly used reagents for flotation of copper ore are Xanthates as collector, pine oil as frother, sodium cyanide as depressant and lime to maintain the slurry alkalinity Concentrate in the form of froth and slurry contains +20% copper(PDF) A Review of the Flotation of Copper Minerals, The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 05%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance ,Combined Effect of Operating Parameters on Separation ,, obtained from the test at 30% solids content, and the collector and frother dosages of 40 and 15 g/t, respectively Keywords Taguchi Flotation Collector Kinetics Copper Sunguncoppercomplex 1 Introduction Froth flotation is a physicochemical process that has been used for more than a century in the concentration of copper sulfide minerals [19]Copper, Recovery of copper is by standard flotation reagents identified in the copper ore flotation description Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
