Способ по пп. 1-4, отличающийся тем, что очищенные хлормагниевые растворы сначала подают в абсорбер печи обезвоживания в кипящем слое и затем в абсорбер аппарата разложения обезвоженного аммониевого карналлита. 6. The method according to PP. 1-4, characterized in that the purified chlorine-magnesium solutions are first fed to the absorber of the fluidized-bed dehydration furnace and then to the absorber of the decomposition apparatus of dehydrated ammonium carnallite. 7. Способ по п. 1, отличающийся тем, что для компенсации потерь хлористого аммония в раствор солей вводят аммиак. 7. The method according to p. 1, characterized in that to compensate for the loss of ammonium chloride, ammonia is introduced into the salt solution. 8. Способ по пп. 1, 2 и 4, отличающийся тем, что после абсорбции хлористого аммония из газов печей обезвоживания и разложения карналлита, газы подают в абсорбер, орошаемый водой, и получают соляную кислоту с содержанием НСl не менее 18-20%. 8.
