Granules are made by reacting (A) MgO with (B) a solution of phosphate and/or Cl, e.g. HCl, NaCl, or MgCl2; (A) may initially be distributed on already prepared granules (C); or (A) and (B) may be premixed the product then being pulverized onto (C). The product, obtained is dried and sieved to give a final product, a fraction which, after crushing the large particles, is recycled as (C). The product is used as mineral feed to cattle. |
