Potash (especially potassium carbonate) has been used in bleaching textiles, making glass, and making soap, since about AD Potash was principally obtained by leaching the ashes of land and sea plants. Beginning in the 14th century potash was mined in of the world's largest deposits, to million tons, is located in the Tigray's Dallol area. different magnesium salts, magnesium chloride was selected. Different processes for the recovery of magnesium chloride from sea water and brines were proposed in the literature. In this study, the extraction of magnesium salts from this specific bittern was studied under atmospheric pressure and at 90°C temperature by fractional evaporation. Bittern, very bitter-tasting solution that remains after evaporation and crystallization of sodium chloride (table salt) from brines and seawater. It contains in concentrated form the calcium and magnesium chlorides and sulfates, bromides, iodides, and other chemicals originally present in . A CORRESPONDENT in NATURE of January 1 (p. ), in asking why it is that the water of the ocean contains such a large proportion of sodium and so little, comparatively, of potassium salts, raises Cited by: 1.
The present invention relates to recovery of industrial grade potassium chloride and low sodium edible salt from bittern as part of an integrated process. The process comprises, mixing low sulphate concentrated feed bittern (a by-product of salt industry) of density to ° Be ( ) with high density end bittern of density to ° Be′ ( Cited by: A new process for recovery of Low Sodium Salt from bittern has been described in the present invention, the said process comprising desulphatation of bittern (by-product of salt industry), evaporation of bittern in solar pans and processing of solid mixture with water to produce a mixture of sodium and potassium chlorides and optionally preparing “free flowing” . Keywords: Bittern, Fertilizer, Magnesium. _____ INTRODUCTION India produces about 70 lakh tons of salt, a year and an equal amount of bittern is also available. In the salt pans of kanyakumari district discharge approximat m 3of bittern during each salt production. This bittern presents a much desirable source of Size: KB. The bromide concentration of sea bittern is − g L-1 at 29 0Bé. Evaporation to − 0Bé increases the bromide concentration to the highest achievable level without significant.
Mixed salts have also been produced from seawater bitterns as intermediate products in the process for the fabrication of potassium sulphate [7, 8]. Magnesium-chloride-rich solution has several important uses as raw material for the fabrication of magnesium oxide and other magnesium-containing chemicals; also it can be used directly in the Cited by: 9. We claim: 1. An integrated process for the simultaneous recovery of industrial grade potassium chloride and low sodium edible salt with overall KCl yield of 90–95%, which comprises (i) desulphatation of bittern with a solution of calcium chloride; (ii) subjecting the desulphated bittern to evaporation until density of 32 to ° Be′ ( –) is .
