Read ArticleDemonstration. Ribbon seaweeds (sp. laminaria) contain iodine compounds which they obtain by extracting iodide ions from seawater. This iodine can be extracted from the seaweed by heating it in air to an ash, in which the iodine is present as iodide. The iodide is dissolved out of the residue by boiling water, the solution filtered and the iodide oxidised to iodine using hydrogen peroxide.

Read ArticleA good way to do this would be to boil the water. When salty water boils only the pure water will turn into steam, but the salt will be left behind. You could do this with a test tube of sea water. Put a little sea water in the test tube and seal with a stopper, but use a stopper which has …

Read Article2.1. Minerals in Seawater Open ocean water contains dissolved salts in a range of 33 to 37 g/L, corresponding to a total mass of some 5 × 1016 tons for a total mass of water of about 1.3 × 1018 tons. Extraction from this huge source is theoretically promising and has been considered in several studies performed in the 1970s [9,10].
Read ArticleUnlike calcium, sodium and potassium hydroxides, magnesium hydroxide is highly insoluble in water, so you can precipitate magnesium and separate it from seawater by adding a strong base such as sodium hydroxide. Once you've isolated the magnesium hydroxide, you can re-dissolve it by adding hydrochloric acid. At this point, you will have isolated the magnesium in the form of a salt, magnesium ...

Read ArticleDeep sea mining is a mineral retrieval process that takes place on the ocean floor.Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean's surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper ...
Read ArticleHow to Separate Salt From Sea Water. By Yvette Clark. Pamela Follett/Demand Media. There are a number of ways to separate salt from water, but if you are interested in obtaining the salt rather than obtaining the sodium-free water, the easiest method is evaporation. It's a relatively simple process, one that people have been using for ...
