Abstract

Fertilizers are obtained by treating blast furnace slag with nitric acid in such a way that the silicates in the slag are converted into colloidal silicic acid, and adding other fertilizing salts, e.g. ammonium sulphate, ammonium nitrate, to the reaction mass. The treatment with nitric acid is carried out at a high temperature and, if necessary, under increased pressure. Specification 356,668 is referred to.
