Flotation of Copper Ores - Mineral Processing & Metallurgy

Flotation of Copper Ores. Treating coarser material or ores that contain a large percentage of heavy gangue (such as in the Coeur d’Alene), it has been found advantageous to increase this to as much as 4½ in. per foot to prevent the blanketing of the porous medium by coarse sand collecting on the bottom.

Copper Flotation - Mineral Processing & Metallurgy

Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter.

Copper Flotation - Elmhurst College

The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of stone mills) to make bubbles, an alcohol to strengthen the bubbles,...

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.

Flotation of Copper Sulfide Ores - PDF Free Download

It is common practice that during flotation of porphyry copper ores containing clay minerals, the copper froth becomes highly flocculated after xanthate collector additions, resulting in dry froth that is difficult to remove. To prevent froth dryness, a collector with frothing properties in combination with two or more frothers is used.

(PDF) Flotation of an Oxidized Copper Sulfide Ore

The grinding and flotation chemistry were compared and linked to the flotation behaviour of the ore samples. The results reveal that as oxidation progressed the copper metallurgy deteriorated.

(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.

The effect of clay minerals on the process of flotation of ...

Mar 15, 2019 · There are some important differences between the flotation of copper ores and other applications. First, several types of mineral species that contain copper can be found (CuFeS 2, Cu 2 S, CuS, Cu 5 FeS 4, and Cu 3 AsS 4, among others) which respond differently to the oxidizing and reducing conditions of the particulate system. As a result, some ions such a copper, iron and arsenic can be …

Copper extraction - Wikipedia

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant.

Froth flotation - Wikipedia

By 1991, the average grade of copper ore mined in the US had fallen to only 0.6 percent. Waste water treatment. The flotation process is also widely used in industrial waste water treatment plants, where it removes fats, oil, grease and suspended solids from waste water. These units are called dissolved air flotation (DAF) units.

60 Centuries of Copper: The Flotation Process

The Flotation Process Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of …

Flotation of a copper sulphide ore from Okiep using thiol ...

froth flotation performance obtained with a bornite-rich copper sulphide ore from Okiep Copper Mine with a feed grade of 1.8% copper. Batch flotation tests were used to assess the performance in terms of mass-water recovery, sulphur grade-recovery and copper grade-recovery relationships and the Klimpel rate constant for copper recovery.

Flotation of Gold and Gold-Bearing Ores - ScienceDirect

For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper …

copper flotation plant - Jiangxi Hengcheng Mining ...

According to the differences of physical and stone properties of copper ore surface, copper ore flotation production line is treated by flotation reagents, the copper deposits are selectively stick to the bubbles for the purpose of separation. Copper flotation process is divided into several stages, such as crushing, grinding and flotation etc.

A New Application For Flotation Of Oxidized Copper Ore

flotation of oxide copper-cobalt ores, using sodium hydrosulphide as the sulphidising agent, has been practiced in Katanga, Democratic Republic of Congo. With sodium

Chapter 12: Flotation of Copper Sulfide Ores | Engineering360

Chapter 12: Flotation of Copper Sulfide Ores 12.1 COPPER ORES AND MINERALS More than 170 copper-containing minerals are known and only 10-15 of these minerals have any economic value. The most important economic copper minerals are chalcopy-rite, chalcocite, bornite and covellite.
