    摘要： The invention relates to iron sulfate which comprises an inert carrier material in an amount of from 0.5 to 4.5 % by weight, based on the amount of iron sulfate used. The iron sulfate comprising the inert carrier material has a screen size with a screening refuse on a 0.2 mm screen of more than 35 % by weight and with a screening refuse on a 10 mm screen of less than 1 % by weight. The iron sulfate used can be water-free or can contain hydrate water (e.g. 1 to 7 mole hydrate water per mole iron sulfate). The iron sulfate can be iron(II) sulfate or iron(III) sulfate or a mixture thereof. Iron(II) sulfate can be used in the form of green salt or filter salt. The inventive iron sulfate is used in agriculture as fertilizer additive, moss control agent, pesticide and lawn fertilizer, in sewage treatment (precipitants and flocculents), in the production of iron oxide products, especially iron oxide pigments, as additive in animal food and as additive in cement, mortar and concrete.

    摘要： Gypsum plaster and gypsum wallboard products can be made from fluoroanhydrite by contacting the fluoroanhydrite with a reactive silica selected from the group consisting essentially of Portland cement; perlite; calcium, sodium or potassium silicates; pyrogenic colloidal silica and diatomaceous earth; and after gradual conversion of the fluoroanhydrite to substantially pure fluorogypsum, the purified gypsum is processed in customary fashion in the industrial manufacturing of plaster products. The reactive silica may be added to the fluoroanhydrite during the gradual aging conversion in water to fluorogypsum; or it may be added during water calcination of the fluorogypsum to stucco; or to the gauging water during gypsum plaster or wallboard product formation from the fluorostucco.

    摘要： Du plâtre de gypse et des produits de plaque de paroi en gypse peuvent être fabriqués à partir de fluoroanhydrite en mettant en contact le fluoroanhydrite avec une silice réactive sélectionnée parmi le groupe comprenant essentiellement le ciment Portland, la perlite, le calcium, le silicate de sodium ou le silicate de potassium, la silice colloïdale pyrogénée et les terres de diatomées; après conversion progressive du fluoroanhydrite en fluorogypse sensiblement pur, le gypse purifié est traité de manière conventionnelle dans la fabrication industrielle de produits en plâtre. La silice réactive peut être ajoutée au fluoroanhydrite soit pendant la conversion graduelle par vieillissement dans l'eau en fluorogypse, soit pendant l'hydrocalcination du fluorogypse en stuc, soit à l'eau de jaugeage pendant la formation de produit de plaque de paroi ou de plâtre de gypse à partir du fluorostuc.
