Abstract: The invention relates to a fertilizer granule comprising both a nitrate and urea as the main nitrogen source. A mineral added during production is an important component in the composition, said mineral stabilizing these otherwise poorly compatible nitrogen compounds. A high nitrogen content is thus attained with ammonium nitrate concentrations falling below maximum limit values set by international legislation and classification, while at the same time the explosion risk particularly associated with the use of ammonium nitrate is avoided. The invention is also directed to a process for the production of the fertilizer granule of the above type, said process resulting in a fertilizer granule with excellent resistance properties and a high nitrogen content, wherein said granule may be coated by methods typical in the art, if desired.

Abstract: The invention relates to a method for preparing a suspension containing phosphate stepwise directly from raw materials, from phosphoric acid of fertilizer quality, a base and organic additives. In accordance with the method, the phosphoric acid is preneutralised with the base, the organic additives are added, nucleation is controlled and phosphate salts are cooling crystallised in order to form a suspension. The phosphate suspension prepared with the method of the invention is applicable to seed coating.

Abstract: In the method, the spent stripper solution for tin or a tin mixture is treated to precipitate dissolved or suspended metal compounds. On the one hand chemicals for reuse, and on the other hand metals such as copper, tin, lead and/or iron are recovered from the waste water streams. Efficiency of the precipitation is improved by heating of the stripping solution at elevated temperatures, and by the addition of a precipitating reagent. Once the precipitate is removed, the remaining liquid may be reused, typically as an admixture with a fresh solution. In the production method of a regenerated stripping solution for tin comprising at least one inorganic acid, ferric ions, at least one organic acid, and at least one organic additive, the stripping solution is heated at elevated temperatures, precipitating reagent is added, precipitated matter is separated and removed, and one or some of the acids or additives mentioned are added for the recovery of the desired tin stripping capacity.
