The invention belongs to the technical field of mining technology and in particular relates to a method for mining a
chloride type
solid kalium mine in a
saline. The process flow of the method comprises the following steps: a
solvent is prepared, filtered and soaked; and
hyperkalemia brine is obtained through mining. The process condition comprises that the prepared
solvent in
solvent preparation comprises the following chemical compositions in weight percentage: 16 to 22 percent of
magnesium chloride, 0.4 to 6 percent of
sodium chloride and the balance being other chemical substances and water. The soaking time of the solvent at a time in soaking is between 20 and 72 hours. By adopting the method, the conversion rate of
dissolution reaches as high as 80 percent;
saline bittern is adopted as a
raw material to reduce environment
pollution and production expenses; rock salt in the
solid kalium mine of the
saline can not be dissolved; the stratum structure is effectively protected; in addition,
sodium chloride in a salt layer can not be precipitated from the solvent in
dissolution in a large amount so as not to block the original holes in the salt layer.
