The present invention relates to natural crude salt formulations arid their cost-effective preparation. In particular, the invention discloses the fractionation of seawater into three fractions which can thereafter be suitably combined to reconstitute seawater in its pristine form for its various applications such as growth of marine microbes, flora and fauna in a marine environment, especially where such environments have to be created in locations far removed from the sea and/or where there is a requirement to modify the composition of seawater to better its performance. The fractions can also be blended appropriately to exclude the major constituent, namely sodium chloride, and thereby be useful for mineralization/re-mineralization of waters which are deficient in mineral nutrients such as calcium, magnesium, potassium, sulphate and bicarbonate including rain water and desalinated waters obtained through thermal/RO desalination. The invention can be practiced most cost-effectively in solar salt works operated on sea brine.
