Copper Ore

W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001. 1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral ...

60 Centuries of Copper: The Flotation Process

Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution. The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a ...

The frothers, such as methyl isobutyl carbonyl, TEB (alkoxy paraffin and pine oil), Dow 250, Dow 1012 (glycols), HP700 and HP600 (alcohols in amine oxide) are typically used in the flotation of porphyry copper and copper molybdenum ores[6]. In copper flotation plants, an increase of 1% 2% in recovery and/or grade is economically remarkable.

Copper Mining and Processing: Processing of Copper Ores ...

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Flotation Circuit: Concentrate Grade and Recovery

The texture of particles within a flotation cell play a pivotal role in both mineral recovery, and the grade, in the flotation concentrate. Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum grade-recovery possible for a given feed ore.

Copper Flotation

A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation.

Copper extraction

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.

Flotation Reagents

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

Copper activation option for a pentlandite–pyrrhotite ...

May 30, 2016· Different sulphide ores respond differently in the prospect of copper activation to thiols for froth flotation. With the BCL Selebi-Phikwe ore body, pentlandite–pyrrhotite–chalcopyrite co-occur and there is the constraint of fine pentlandite dissemination in the pyrrhotite, so that liberation is limited. In the presence of pentlandite, pyrrhotite can even be galvanically depressed.

INTERPRETATION OF FLOTATION DATA FOR THE DESIGN OF …

For a testwork laboratory treating a wide variety of ores, the most useful laboratory flotation machine is probably one with cells of 500, 1000 and 2000g capacities, with a different diameter impeller for each cell, with stainless steel or rubber-covered impellers, glass or plastic cell bodies, and requiring an outside source of low-pressure air.

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
