flotation separating copper ore concentrate machine

Copper processing is a complicated process that begins with mining of the To remove the ore, boring machinery is used to drill holes into the hard rock, a process called froth floatation is used to separate the copper minerals from the gangue. copper and other metals; this copper concentrate is then sent to the smelter.

Gangue | geology | Britannica.com

In copper processing: Mineral processing …from the waste materials, or gangue. In cases where the next step is leaching (most frequently in the case of oxide ores), complete liberation of the copper minerals is not always necessary; the ore needs to be crushed and ground only to the extent required to expose the surface of…

Misplacement of gangue slimes to concentrates also can pose significant concentrate dilution issues as well as requiring much higher flotation residence times to ensure high copper mineral recovery. In a plant where the flotation capacity is fixed, this means lower copper recoveries.


Concentrate "A" has the sulphides being mostly chalcopyrite and some pyrite and a higher gangue fraction. Concentrate "B" distributes its copper mostly between chalcopyrite and tennantite and has considerably more pyrite. The mercury mineralogy for the two concentrates was quite different as shown in Table 5:

Copper extraction - Wikipedia

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically grade between 37% and 40% copper-in-concentrate, as chalcocite has no iron within the mineral.

the plant historical copper concentrate grade data showed that a large portion of liberated, non-sulfide non- floating gangue material was being recovered to the copper concentrate via entrainment. particle size and mineralogical data for January 2014 were collected from the plant and reported by als, (als Quantitative automated

copper processing | Definition, History, & Facts | Britannica.com

The reagents provide an attraction between the surface of the copper minerals and the air bubbles. As the bubbles rise to the surface, they carry the copper minerals with them, leaving gangue minerals in the cell to be discarded as tailings. Collection of the froth from the surface of the flotation cell yields a copper concentrate.

copper concentrated gangue - dsports.co.in

A copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal.

Learn About Copper, the Ductile and Malleable Base Metal

Regardless of the ore type, the mined copper ore must first be concentrated to remove gangue, unwanted materials embedded in the ore. The first step in this process is crushing and powderizing ore in a ball or rod mill.

Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals.

copper concentrated gangue - manveesingh.in

Copper extraction - Wikipedia 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.

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

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.

The standard flow sheet consists of bulk sulphide flotation of copper and molybdenite while depressing gangue and iron minerals in the rougher and cleaner circuits. Recovery of copper is by standard flotation reagents identified in the copper ore flotation description.

Copper Flotation - Metallurgist & Mineral Processing Engineer

Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate.

Copper mining. From ore to copper. - SchoolScience.co.uk

About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue). The most common copper minerals are:

COPPER Copper production - TU Delft

Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 % Cu) must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue.
