  • Publication number: 20210368840
    Abstract: The present invention relates to a process to prepare a free-flowing salt product comprising sodium chloride (NaCl) and/or potassium chloride (KCl), wherein the salt product has a particle size of from 50 ?m to 1000 ?m, which process comprises the steps of (a) processing a source of pure NaCl, pure KCl, or mixture of salts, to form particles with an average size of less than 100 micrometer; (b) subsequently, compacting the particles from step a) using a pressure of from 40 to 400 MPa; and optionally, crushing the thus obtained particles; and (c) subsequently, absorbing one or more agents into the salt particles, characterized in that no agent is added in or during steps a) and b) or between steps a) and b).

  • Publication number: 20210282441
    Abstract: The present invention relates to a process to prepare a salt product containing sodium chloride (NaCl) and at least one additive, wherein the salt product has a particle size of from 50 ?m to 10 mm, which process comprises the steps of: a. optionally, crushing a sodium chloride-containing material to a particle size that is between 1,000 times smaller and 3 times smaller than the size of the final salt product; b. optionally, crushing the at least one additive starting material to a particle size that is between 0.5 and 2 times the particle size of the sodium chloride-containing material particles resulting from step a.); c. subsequently, mixing the sodium chloride-containing material particles of a particle size that is between 1,000 times smaller and 3 times smaller than the size of the final salt product, and additive particles of a particle size that is between 0.5 and 2.0 times the particle size of the sodium chloride-containing material particles; d.
