Water dissolves the salt (impurities such as ashes do not force back dissolved) Pressure pushes salt settlement up to the surface. Salt solution (brine) is stored above the ground.
Salt crystals are recovered(p) by evaporating the water * g ived for the chemical industry ! * Could look at to widespread subsidence and flooding of land * Extracting salt from the ocean * Evaporate the water and separate the salt * Used for dwelling use * large extractions are victorious place where the water is hot and dry. In these places there is no need to contract fuel to separate salt, energy comes from the Sun * Large-scale extractions can have an effect on the inhabitants of the area * Underground mining * Use giant machines to extract rock salt....If you want to get a full essay, order it on our website: BestEssayCheap.com
