Abstract:
    The invention relates to new alkali cyanide granules based on sodium cyanide or potassium cyanide and also a process for the preparation thereof. Commercial alkali cyanide granules comprise irregular particles: disadvantages are, in particular, the tendency to form dust and lumps. Alkali cyanide granules of the invention have practically no abrasion and a reduced tendency to form lumps. The granules are characterised by essentially spherical particles, particle diameters in the range from 0.1 to 20 mm, a bulk density above 600 g/dm
