Seawater

Seawater, or salt water, is water from a sea or ocean.On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/l, 35 ppt, 599 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na +) and chloride (Cl −) ions).Average density at the surface is 1.025

Mining and Water Pollution — Safe Drinking Water Foundation

Jan 23, 2017Heavy metal pollution is caused when such metals as arsenic, cobalt, copper, cadmium, lead, silver and zinc contained in excavated rock or exposed in an underground mine come in contact with water. Metals are leached out and carried downstream as water washes over the rock surface.

How to Remove Chlorine From Water

Apr 26, 2018The simplest way to remove chlorine is to simply let it evaporate from the water. Chlorine is a gas at room temperature, and in water it's a volatile solute meaning its molecules are diffused in the water, and it will escape into the air over time. The amount of time needed varies with air and water temperature.

Corrosion of Copper

Corrosion rates were monitored for over 24 hours, using linear polarization and potential step techniques. The work has shown that copper-nickel alloys can corrode quite rapidly in deaerated sea water if these normally "passive" alloys are made active by the presence of sulfide, or if sulfur is available as an oxidant.

SEA

All SeaAgri products are produced from the Sea of Cortez containing 92 minerals and trace elements, plus more than 50,000 organic compounds. Scientific data shows that SEA-90's minerals and trace elements stimulate, feed and enhance micro flora populations in soil, and as little as one ounce of SEA-90 Essential Elements provide nearly complete mineral nutrition.

How To Remove Iron from Well Water – Fresh Water Systems

Birm Birm is another type of oxidizing media used to extract dissolved iron out of well water supplies. Unlike manganese greensand, birm does not require a chemical oxidizing agent to remove the iron. However, birm only works in water with elevated pH levels. Therefore, most systems utilizing birm will combine it with calcite.

acid base

Copper(II) oxide is basic and reacts with acids to form a copper salt and water. A strong acid, like HCl, reacts faster than a weak acid - like acetic acid (which is the main acid component of vinegar). If one adds NaCl to vinegar, you get HCl: $$ce{CH3COOH +NaCl=CH3COONa +HCl}$$ Copper(II) chloride dissolves in the water.

Hot, acidic conditions are required to extract metals like iron, copper and zinc from the rock and carry them in solution. Fluids at Lost City do contain high levels of hydrogen sulfide, but the level of metals is extremely low because of the high pH, so there is no smoke.

May 02, 2013Anion-exchange was used to purify copper from the metal-rich extract. who made the first measurements of δ 65 Cu in riverine and sea water. They suggested that the Cu isotopic composition in marine systems was a reflection of the seawater Cu source overprinted with biological uptake and remineralisation processes.

Copper in the Roman Empire

The resulting solution contained copper in the form of copper sulfate. There was far more copper in the water than in the mine water collected by the Romans. Iron was placed into the water containing copper sulfate. A reaction occurred, in which the iron dissolved into the water, and copper precipitated where the iron had been.
