Effects of aluminosilicate minerals on coppermolybdenum flotation from

Copper Flotation and sodium hexametaphosphate (20 40 and 40 by weight respectively) at 200 and 300 g/ton. The reagent mixture (case b) at a dosage of 200 g/ton improved the copper recovery and decreased the grade

sometimes. Highviscous oils used in flotation of porphyry copper allow molybdenite recovery from 80 to 90 79 . It has earlier been found that reagents DMIPEC and DC80 increase metal extraction in concentrates. In flotation of base metal ores DMIPEC and DC80 present as selective auxiliary collectors with foaming properties at the

Copper Porphyry Potential The first phase of drilling and surface work has provided several lines of evidence that a porphyry target exists in the central region of the mineralized system as it is currently defined. An analysis of vein geochemistry across the property has demonstrated concentric zonation with copperleadzinc zoning outward

A study on the effect of active pyrite on flotation of porphyry copper ores

Abstract Active pyrite is one of the most undesirable phenomena in the flotation of porphyry copper ores. Misreported pyrite into copper concentrates decreased the grade and recovery of copper. In this study the effective parameters on the flotation process including grinding condition and chemical

Revisiting the Cumulative GradeTonnage Relationship for Major Copper

Both avenues of inquiry into copper supply have been explored in the literature and this paper will provide an analysis of supply quality—specifically the relationship between ore tonnage and grade for copper on the global scale. Examination of metal tonnage and grade is not new both for copper and metals in general. DeYoung (1981) provided

Improving copper flotation recovery from a refractory copper porphyry

In this paper NpropylNethoxycarbonyl thiourea (PECTU) collector was investigated to concentrate copper minerals from a refractory copper porphyry ore through benchscale and industrial flotation tests. The flotation results indicated that PECTU had strongly collecting power for copper sulfide minerals and excellent selectivity against iron sulfide minerals under moderately alkaline conditions.

Model Discrimination in the Flotation of a Porphyry Copper Ore

Thirteen of these have been applied to batch flotation data and evaluated with respect to one another using statistical tests were carried out on samples of a US porphyry copper ore (Pinto Valley AZ). The ore was tested using various collector and frother systems to produce different timerecovery profiles.
