PROCESS TO PREPARE SODIUM AND/OR POTASSIUM SALT PRODUCTS, SALT PRODUCT OBTAINABLE THEREBY AND THE USE THEREOF
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 μm to 1000 μm, 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).
1 .- 4 . (canceled)
5 . 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 μm to 1000 μm, 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), and wherein the agent is in liquid form, not being water or any other liquid in which the salt dissolves for more than 5% by weight at 20° C. at 1 atm (1,013 bar).
