treatment processes on copper mine Depending on the type of copper-bearing minerals in the ore and the treatment processes used, the concentrate contains copper from around 25% for chalcopyrite (CuFeS 2) ores, increasing to over 50% for bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S) or The concentrate is then smelted to float off as slag the iron oxides and iron sulphid

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Another example relating to treatment of intrusion water from a copper mine is shown below. This example shows the reduction of contaminants from dam water entering the mine’s water treatment plant. The water was first treated by MF-RO and the concentrate was subsequently treated by a Disc- TubeTM RO system with the following results:

The copper is deposited on the cathode and the gases produced at the anode (O 2, Cℓ 2) are recovered selectively and returned to the process. This method produces an extremely pure copper that can then be rolled (hot or cold), drawn or even formed into tubes before being sold. Wastewater treatment is extremely important in these factories.

This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted. There are two main ...

27-2-2019· Treatment of complex copper in waste water. A discussion started in 2004 but continuing through 2019. 2004. Q. Does anyone know of a de-complexing agent for copper. I remember years ago there where such things, all be it very expensive. Basically we are trying to treat waste water after after various copper bearing processes.

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks ...

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

1-1-2006· Acid Mine Drainage (AMD) is produced when sulfide-bearing material is exposed to oxygen and water. The production of AMD usually – but not exclusively – occurs in iron sulfide-aggregated rocks. Although this process occurs naturally, mining can promote AMD generation simply through increasing the quantity of sulfides exposed.

smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods of cop-per production have remained unchanged for 65 years. Moreover, six of the mines opened be-tween 1900 and 1920 are still among the major copper producers in the United States today.

Veolia supplied this copper mine with a plant for drinking water and a plant for wastewater treatment. The potable water treatment plant uses clarification processes, followed by sand filtration and activated carbon filtration to produce water for use and consumption by mine workers.

Osmoflo was subsequently engaged to provide a permanent 3 MLD seawater reverse osmosis plant for process and potable use at the mine. This was commissioned in February 2016. Antucoya Mine is operated by Antofagasta Minerals, a Chilean-based copper mining group traded on …

impact. El Teniente site, a copper mine located in Chile is currently equipped with a cobalt removal water treatment plant before discharge to the environment. Some extensive pilot tests were conducted using softening, ultrafiltration and reverse osmosis for further reducing the effluent sulphate concentration.

membrane treatment processes if scaling mine waters require treatment. The frequency of ion-resin regeneration can be reduced by pretreatment of the mine water (e.g. limestone/lime process). Similar to the water produced in membrane treatment processes,
