FIELD: chemistry.
SUBSTANCE: invention relates to technology of recycling fluoro-anhydrite, a by-product of hydrofluoric acid production. The method involves adding a lime-containing component to fluoro-anhydrite in order to neutralise the sulphuric acid component, granulating the obtained mixture and then using the granules in production of construction materials. The lime-containing component used is dispersed electric steel melting slag in amount of 5-85% of the weight of the fluoro-anhydrite.
EFFECT: improved strength properties of the recycling product, simple and cheap technology of recycling fluoro-anhydrite.
