Thread: Is it easy to harvest salt from seawater?

    Scrape the salt off of the leaves of mangroves. Oh, and by the way, if you do worry about this until you get an ulcer. Bark extracts from the red mangrove have been used to treat gastric ulcers. So stick that in you dried mangrove bud and smoke it.

    I believe there are areas... maybe it was Sardinia or Sicily, where they still harvest salt from the ocean by evaporation it in huge flat areas that look like rice paddies near the coast.

    Ya... Google image is my friend:

    Years ago I was on a wind surfing trip to Bonaire. There were quite a few of the salt evaporation ponds like the ones in the image link that Chris posted.

    In my area, salt isn't that much of a problem. Apparently there is almost 5 billion tons of salt in the lake near my house. 2.5 million tons are commercially extracted from it annually. http://ut.water.usgs.gov/greatsaltlake/

    To the OP, just do this. Fill a pot with sea water, and then leave it out in the sun. A couple of days later, fill it up again. Repeat for a month or two, then just leave it to completely dry up. Super easy.

    There are also huge salt evaporation ponds in the San Fransisco Bay area.

    Salt evaporation is big business in many third world coastal nations. A small farmer can build a series of evaporation ponds and have a constant supply of salt to harvest. They can make a subsistance living on just a couple of acres even if the ground can not be used for agriculture.

    No but I can picture him para sailing from the back of the sub. The Chief of the Boat gets to do anything he wants.

    Captain: "We have two Russian subs in the vicinity. I want absolute quiet."
    XO: "Uh, Captain...The Chief....." Points toward surface.
    Captain: "Again!?

    Way of making salt at home
    Place 5 liters of seawater in large pan, gives about 100 grams of salt.
    Check the height of the water and divide by nine and mark this point.
    Heat the water without boiling. In the oven at 70-90ºC until only get this ninth.
    Remove the water discarding waste.
    Replace the pan and mark a fifth of the height.
    Heat the water until this fifth part.
    What is at the bottom of the pot is Sal.
    Pass a water strainer and discard the water
    The strainer is 1st quality salt.

    I used to live on the ocean and had the same question put a bowl in the center of a pot with a lid...invert the lid so the condensation drains into the bowl. uploadfromtaptalk1456439709208.jpg
