Abstract

A process for preparing a complex fertilizer comprises decomposing raw material with nitric acid of phosphorus, calcium nitrate removal by crystallization upon cooling, neutralization with ammonia evaporation. The resulting nitric acid solution with low grade phosphorous raw material is mixed with urea. The resulting slurry was sent to filtration, the clarified solution is separated and neutralized with ammonia for direct processing in complex liquid fertilizer. A solid crystalline mixture fed to the dryer drum to yield a solid fertilizer, consisting of a mixture of calcium phosphate, nitrate and urea phosphate.
