Copper mineralization occurs in many forms and in a variety of geological settings.As such, there are various factors to consider when determining the value of different types of copper deposits.
The Influence of Textural Variation and Gangue Mineralogy on Recovery of Copper by Flotation from Porphyry Ore – A Review A F Cropp1, W R Goodall2 and D J Bradshaw3 ABSTRACT
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
12.4.2 Reagent schemes in flotation of porphyry copper and copper–molybdenum ores Reagent schemes used for the treatment of porphyry copper and copper–molybdenum ores are relatively simple and usually involve lime as a modifier, xanthate as the primary collector and a secondary collector.
Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum metallurgy and ...

The importance of flotation separation has long been, and continues to be, an important technology for the mining industry, especially to metallurgical engineers. However, the flotation process is quite complex and expensive, in addition to being influenced by many variables. Understanding the variables affecting flotation efficiency and how valuable minerals are lost to the tailings gives ...

Major miners look to copper porphyry deposits for large-tonnage, low-cost operations. We take a look at what makes for a copper porphyry takeover target.
sometimes. 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. In flo-tation of base metal ores, DMIPEC and DC-80 present as selective auxiliary collectors with ing properties; at the
Here let's understand the geology of porphyries and iron oxide copper gold deposits or IOCG as they are known. These are somewhat the giants of the ore deposits world. As a mining interested learner, the geology of porphyry copper deposits is vital to your education.. Now in the first Exploration Geology Course I discussed how because our current mining technology all the metals that we use ...
Education Resources Copper Mining and Extraction: Sulfide Ores . It's hard to imagine a world without copper. We rely on copper for power, lighting, heating, communications, water supply and transport. ... Porphyry copper – Nazca subduction – Global volcanism smithsonian. ... Froth flotation
9/12/2012· This shows you the froth produced by flotation on a porphyry copper ore of about 1.5% Cu. You see the rougher flotation, the cleaner and scavenger circuit. It is a very small pilot plant small ...
Despite extensive studies of the influence of aluminosilicate minerals on coal flotation (Jowett, 1956, Arnold and Aplan, 1986, Oats et al., 2010), little work has been done to determine the influence of aluminosilicate minerals on the flotation of non-metallic minerals (Plaksin and Ocolovich, 1965) and porphyry copper ores (Bulatovic et al ...
For each test, 1000 g of the porphyry copper ore was wet ground using a ball mill to 65 wt% passing 200 mesh. The slurry was transferred into the flotation cell while agitating at approximately 2000 rpm for 2 min. Flotation tests were performed in a 3L XFD Ⅳ flotation cell. The flotation flowsheet and corresponding conditions are shown in Fig. 2.

Porphyry copper and porphyry molybdenum deposits are the world's largest sources of copper (~60%) and molybdenum (~95%) and commonly contain 100s of million metric tons (Mt) to >20 billion metric tons (Gt) of ore (Seedorff et al., 2005; Sinclair, 2007; Singer et al., 2008; John et al., 2010; Sillitoe, 2010; Taylor et al., 2012).These deposits formed from large magmatic-hydrothermal systems ...
Porphyry copper ore beneficiation: Copper flotation using compared commonly simple copper ore dressing process, after primary grinding, fineness of 200 mesh accounted for about 50% to 70%, one roughing and 2-3 times selection, 1 - 2 times scavenging.

Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs.
Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-
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 ...

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.
