process of iron water mining in the seas

6 Seawater Mining - Energy

Extracting minerals from seawater is a more environmentally friendly enterprise than terrestrial mining (Diallo et al. 2015; Parker et al. 2018). Moreover, seawater extraction will not require fresh water for processing nor create volumes of contaminated water and tailings for disposal. Most REEs, as well as uranium and other

Deep sea mining - Wikipedia

Apr 03, 2007  Mining sites. Deep sea mining is a relatively new mineral retrieval process undergoing research which takes place on the ocean floor.Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at about 3,000 – 6,500 meters below the ocean's surface. The vents create sulfide deposits, which contain precious metals such as silver, gold ...

Aug 15, 2008  Mining and associated smelting and metal processing activities have led to perturbations in the cycling of metals in the surface environment. In this context, iron-ore mines act as important sources of major metals, mainly Fe and Mn, but also associated trace metals into the environment (Ratha and Venkataraman 1995; Wong 1981; Zabowski et al. 2001).

The Effects of Iron in Water on Aquatic Life Cuteness

Iron in water has many effects on aquatic life, both good and bad. Iron (Fe) occurs naturally in water at a rate of roughly 1-3 parts per billion (ppb) in ocean water, about 1 part per million (ppm) in river water and 100ppm in groundwater. Iron comes from various minerals in the soil, which is why ...

Managing water consumption in mining

Aug 21, 2013  Water for the project has to be sourced from two dams and Lake Argyle, meaning it could have potential impacts on ground water. In 2005 the mine used more than 3,500 megalitres of water from the lake to run operations. By 2009 they had reduced this to 300 megalitres – a 95% drop.

Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites. Most iron is found in minerals formed by the combination of iron with other elements. Iron oxides are the most common.

Manganese nodules « World Ocean Review

The formation of the manganese nodules is conceivably simple. Dissolved metal compounds in the sea water precipitate over time around a nucleus of some kind on the sea floor. The growth core can be, for example, a shark’s tooth or a fragment of a clam shell, around which the nodule grows. This growth process can take place in two ways.

Therefore, the iron atom readily gives up electrons when exposed to oxygen. The chemical reaction is given by: Fe → Fe 2+ + 2e – The oxidation state of iron is further increased by the oxygen atom when water is present. 4Fe 2+ + O 2 → 4Fe 3+ + 2O 2-Now, the following acid-base reactions occur between the iron cations and the water molecules.
