copper ore tailings

Tailings dam

There are key differences between tailings dams and the more familiar hydro dams. Tailings dams are designed for permanent containment, meant to quot;remain there foreverquot;. Copper, gold, uranium and other mining operations produce varied kinds of waste, much of it toxic, which pose varied challenges for long term containment.

USE OF COPPER ORE TAILINGS AS AN EXCELLENT POZZOLANA

Copper ore tailings, is a waste material obtained in the copper mines, after the extraction of copper concentrate from the ore. Some trace percentage of copper will be left in the ore after the extraction process is completed.

How copper is made material, used, processing, steps

Most of the copper ores mined in the United States contain only about 1.2 1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2 , also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.

Copper Tailings Elmhurst College

Water Reclamation and Tailings. The concentrated ore, now called copper concentrate, is dewatered and dried to about 10% moisture content. It is shipped by truck to the Asarco smelter in Hayden, Arizona. (The El Paso smelter is on stand by status). Water is recovered from the tailings in another thickener.

Recovery of Rutile Titanium Dioxide

Characterization studies of the porphyry copper mill tailings used for this research showed that the tailings material contained 0.75 TiO2. Rutile was the most abundant TiO2 mineral. Mineralogical examination of the ore after it was ground to pass 200 mesh showed that about 30 percent of the TiO2 remained locked and that nearly 17 percent of

Tailingsfo What are tailings? Their nature and production

Tailings characteristics can vary greatly and are dependent on the ore mineralogy together with the physical and chemical processes used to extract the economic product. Ritcey (1989) reported that tailings of the same type may possess different mineralogy and therefore will have different physical and chemical characteristics.

Tailings Impoundment QA Kennecott

metals have been removed from the ore extracted from the Bingham Canyon Mine. The rock is crushed and ground until it is the consistency of fine sand. The ore is then separated from the tailings using a separation process. Tailings are transported to the tailings impoundment as mud like slurry where the solids settle out and the water is recovered.
