Alkali metal or alkaline earth metal peroxides, for example, particularly, calcium peroxide, is produced by recovering a moist peroxide product from an aqueous mixture, formed by reacting hydrogen peroxide and a hydroxide of the alkali metal or alkaline earth metal, and drying the moist product by means of a pneumatic conveyer drier. The peroxide so produced is suitable for granulation. Alternatively, particulate substances, such as seed, are coated with the peroxide by bending with the moist peroxide product and passing the blend through the pneumatic conveyor drier. |
