Abstract

A method for preparing hardened granules from a particulate material which comprises admixing to the particulate material an aqueous inorganic binder, converting the resulting moist mixture into granules and hardening said granules, characterised in that it comprises the steps of: (i) selecting a particulate material comprising ingredients suitable as a raw material or an agent in a selected chemical or physical process; (ii) where applicable bringing the particulate material to a particle size distribution suitable for aggregation into granules; (iii) composing and mixing a mixture comprising: the particulate material; an aqueous inorganic binder selected from the group consisting of a calcareous binder, cementitious binder, hydraulic cement, Portland cement, high alumina cement, a mixture of a source of calciumhydroxide with a source of silica, lime, gypsum and dolomite; bringing about a moisture content so that a granulatable mixture is obtained; (iv) forming granules; (v) hardening said granules at a temperature above room temperature and below the boiling temperature of the moisture whilst sticking together of the granules is avoided and where applicable excess moisture from the granules is extracted; (vi) withdrawing the hardened granules in the form of a feed stock component for said selected process.
