pokkets says: Solve two problems at once. Not to mention, the vast amount of dissolved minerals, and metals, present in seawater, which could be refined from the salt. I wonder how close they are to a practical application. Does this affect the marine habitat? This would be an excellent student research topic. The return of what they call hypersaline water to the ocean could have critical effect on any marine environment. It does seem a typically aloof means of disposing of what we don't want, when the environment is bound to want it less. There is a desalination plant being built in Sydney Australia. however under water pipelines being built to carry the water north, are reported to be stirring up heavy metals and toxins, that have settled on the bottom of Botany Bay, as a result of years of industrial pollution. Deciding to return the hypersaline water is the equivalent of denying it's existence. There is more than salt in the water, but the volumes suggest that there would be amounts of valuab... "The only metal that has ever been successfully isolated in significant quantities from seawater is manganese. In some areas of the world, the ocean bottom is covered in many trillions of manganese nodules, the dust of which is dissolved in the sea water. In fact, as much as 1/1000th of seawater, by weight, is manganese. There is so much manganese in the ocean that it is the primary source for many large countries, such as the United States. The extraction process is simple. It may not be gold, but it does come in handy." From http://www.wisegeek.com/can-gold-be-extracted-from-seawater.htm Extracting minerals from hypersaline may be more efficient than from seawater. Has anyone tr... |
