USE OF PARTICLES OF SALT, AND PROCESS OF PREPARATION OF FREE-FLOW SALT PRODUCT. The present invention relates to a free-flowing salt product preparation process comprising sodium chloride (NaCl) and/or potassium chloride (KCl), wherein the salt product has a particle size of 50 μm to 1000 μm and the process comprises the steps of (a) processing a source of pure NaCl, pure KCl or a mixture of salts, to form particles with an average size of less than 100 micrometers; (b) then, compacting the particles from step (a) using pressure from 40 to 400 MPa; and, optionally, grinding the particles obtained in this way; and (c) subsequently absorbing one or more agents into the salt particles, characterized in that no agent is added during either steps (a) and (b), or between steps (a) and (b). |
