Popis: The Phosphorus production is associated with the formation of technogenic wastes, such as phosphorus slag, boiler dust and gas emissions. Phosphorus sludge and boiler dust are a valuable secondary raw materials for the production of phosphate fertilizers. However, the reasonable and practically implemented recycling technologies of wastes into fertilizing products are still absent. In this regard, the search for new possibilities of recycling of large tonnage phosphorus-containing secondary raw materials is an important task. In this paper, mixture of phosphorus sludge, boiler dust, ammonium sulphate and humic acid was used for obtaining the fertilizer of type of ammonium phosphate. Technological conditions and basic indicators were identified for the proposed process.
