Copper Froth Flotation

Copper Flotation - Elmhurst College

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, stone recycling and waste-water treatment industries.

Copper Sulfide Flotation - Mineral Processing & Metallurgy

Copper Rougher Flotation. Two or more machines are always provided in series. This allows adequate volume for absorbing surges and fluctuation in feed without cell adjustment. Mineral and middlings in the teeter or quiescent zone of the cell are gradually forced upward to the froth removal zone.

Copper Flotation - Mineral Processing & Metallurgy

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 Mining and Processing: Processing of Copper Ores ...

After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and “worthless” rock, called gangue (pronounced “gang”). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.

60 Centuries of Copper: The Flotation Process

The Flotation Process. In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the stone conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.

Flotation Reagents - Mineral Processing & Metallurgy

Flotation Reagent Pumps. Undiluted liquid .05 to .20 Frother and promoter for gold and sulphides of silver, copper, lead and zinc. Aerofloat 25 25% phosphorus pentasulphide in cresylic acid. Undiluted liquid .05 to .20 In acid or neutral circuit is a strong non-selective promoter and frother …

1 Froth Flotation – Fundamental Principles

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.

Native Copper Flotation - Froth Flotation (Sulphide ...

This might be removed by attrition. Depending on the amount and size of this native copper it could be building a circulating load in the milling circuit. This could be recovered by gravity methods from a bleed stream of the cyclone underflow. This has been used to recover native gold in copper flotation operations.

Froth Floatation Process - YouTube

May 05, 2010 · Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. Historically this …

Copper extraction - Wikipedia

Supergene ores rich in sulfides may be concentrated using froth flotation. A typical concentrate of chalcocite can grade between 37% and 40% copper in sulfide, making them relatively cheap to smelt compared to chalcopyrite concentrates.

Flotation Froth - an overview | ScienceDirect Topics

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10]. Flotation technologies are now widely used for separations such as the beneficiation of low grade Florida …

(PDF) A Review of the Flotation of Copper Minerals

The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance....

Introduction to Mineral Processing - Chevron Phillips Chemical

The froth, enriched in copper and molybdenum, is removed from the flotation roughers and scavengers. This enriched material is now called the rougher concentrate or cleaner feed . The combined rougher-scavenger concentrate may be 5% Cu and 0.06% Mo (a concentration factor of 3 to 10 times is typical).
