Abstract
A method for the production of potassium nitrate by its salting out from an aqueous solution comprising the ions K?+, C1-, M++¿ and NO¿3?- wherein M++ represents Ca++ and/or Mg++, comprising the following steps; (a) dissolving at least one mineral selected from the group consisting of calcium carbobate, magnesium carbonate, magnesium oxide, calcium oxide, calcium hydroxide, magnesium hydroxide and dolomite, in aqueous nitric acid, in an amount which is approximately stoichiometrically equivalent to the amount of nitrate ions in the solution, or dissolving at least one mineral selected from the group consisting of calcium nitrate and magnesium nitrate, in water; (b) dissolving at least one source for potassium chloride, in the solution obtained at step (a) at temperature higher than 40 °C, wherein the amount of the source is chosen such as to obtain an approximately stoichiometric ratio between potassium and nitrate ions and wherein the source is selected from the group consisting of KC1, carnallite, sylvinite, and a mixture of KC1 with MgC1¿2?, NaC1, CaC12 or a combination thereof; (c) cooling the solution obtained at step (b) to obtain a precipitate of potassium nitrate.
