Abstract

Granular compositions containing pulverulent magnesium are made by blending the pulverulent magnesium ingredient with the desired other ingredient(s). To this end, a premix is formed by mixing, in a first stage, the pulverulent magnesium with the other ingredient(s) in a ratio by weight of 4:1 to 1:19; and intimately mixing this pre-mix, in a second stage, with further proportions of said other ingredient(s) giving a total ratio by weight of 1:799 to 1:19.
