  • Publication number: 20200094265
    Abstract: A method is used for treating a salt solution using a treatment system. The treatment system has an evaporation device to which the salt solution produced in an upstream operation is supplied. A crystallizate suspension having kainite, halite, and sylvite is obtained from the evaporation device, and the kainite is then separated from the crystallizate suspension. The method for separating the kainite from the crystallizate suspension has at least the following steps: supplying the crystallizate suspension to a preliminary classifying device in which kainite is partly separated from the crystallizate suspension by means of a preliminary removal process based on the particle size of the kainite, thereby obtaining a kainite-reduced fraction, and transferring the kainite-reduced fraction to a flotation device in which the remaining content of kainite is separated from the kainite-reduced fraction.

  • Patent number: 10118183
    Abstract: The invention relates to a process for selective flotation of kainite from crushed crude potash salts or, for example, from crystallized salt mixtures obtained by evaporation processes, which in addition to kainite may contain further minerals such as halite, sylvine and other salt minerals, for example, in order to produce a kainite concentrate fraction and a residues fraction. The separation process is characterized in that the crushed or crystallized salt mixture is intensively mixed as a crystallizate suspension with a combination of conditioning agents consisting of a sulfated fatty acid or its alkali metal salt as collecting reagent and a frothing agent known for flotation (for example, glycol ether, monohydric aliphatic alcohols, terpene alcohols, polyglycol ethers, etc.) and is then separated by agitator-driven or pneumatic flotation into a kainite concentrate fraction and a residues fraction. The resulting fractions may be further processed in downstream processes.
