A novel approach for preferential flotation recovery of

01/10/2012· There are several flow sheets (listed in Fig. 1a and b) used in the flotation recovery of copper and molybdenum from their porphyry sulfide ores. Fig. 1a is a typical flow sheet that consists of two stages (Raghavan and Hsu, 1984, Bulatovic, 2007, Liu et al., 2011).The first stage, commonly known as the copper circuit, produces a bulk copper sulfide–molybdenum sulfide concentrate.

IMPROVEMENT OF PORPHYRY COPPER FLOTATION EFFICIENCY

High-viscous oils used in flotation of porphyry copper allow molybdenite recovery from 80 to 90% [7–9]. It has earlier been found that reagents DMIPEC and DC-80 increase metal extraction in concentrates.

Effects of aluminosilicate minerals on copper–molybdenum

01/07/2011· The cleaning and re-cleaning stages produce copper concentrate. The reagents used in the flotation circuit are the collectors of Nascol 1451 (dithiophosphate + mercaptobenzothiazol) and Z11 (sodium isopropyl xanthate), frothers of Dow 250 (polypropylene glycol methyl ether), and MIBC (methyl isobutyl carbonyl).

Model Discrimination in the Flotation of a Porphyry Copper

01/05/1985· Flotation 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 time-recovery profiles. These were used to calculate flotation rate and ultimate recovery parameters for each model.

Model Discrimination in the Flotation of a Porphyry

Numerous flotation models have been proposed in the literature. Thirteen of these have been applied to batch flotation data and evaluated with respect to one another using statistical techniques. Flotation 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 time-recovery profiles.

Factors affecting the flotation recovery of molybdenite

N2 Investigations have been conducted to characterize the surface chemical and flotation properties of molybdenite in aqueous environments typical of those that exist in the copper circuits of plants which process porphyry copper ores. These investigations have revealed that molybdenite and quartz particles are negatively charged at the pH commonly used for bulk sulfide flotation, namely 11

Optimizing Performance of SABC Comminution Circuit of

This research is focused on the Phase I SABC milling circuit of the Wushan porphyry copper mine. Improvements to the existing circuit were targeted without any significant alterations to existing equipment or the SABC circuit. JKSimMet simulations were used to test various operating and design conditions to improve the comminution process.

Bench and Pilot Plant Programs for Flotation Circuit Design

The compositing for a porphyry copper deposit metallurgical testwork program will be distinct to that of a massive sulphide ore or that of a vein hosted Au/Ag ore. Sample selection will take place for both grinding and flotation testwork at the same time and will follow similar logic. Relevant criteria include: • Rock type • Alteration type • Mineralogy and/or head grade to assess

Separation efficiency improvement of a low grade copper

The copper flotation circuits upgrade copper content by a factor of 80-160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed (remaining gold is recovered both as a gravity product within the primary grinding circuit and also via leaching of a gold-containing pyrite concentrate). The copper concentrate grades achieved from the flotation

MEI Blog: Challenges in copper flotation

17/09/2011· Flotation of difficult-to-float copper porphyry ores indicates that the primary reasons for the problems are mineralogical diversity, metallurgical factors, and process limitations. A detailed analysis of these factors indicates that, most often, difficulties in the flotation of copper porphyry ores arise due to mineralogy and metallurgy interrelated factors. Identification of the exact nature
