THE BASICS OF THE PHYSICO-CHEMICAL TECHNOLOGY OF OBTAINING SIMPLE PHOSPHORUS FERTILIZERS

The article examines the basics of the physico-chemical technology of obtaining simple phosphorus fertilizers from aznekic phosphorites, which is becoming more and more relevant in the context of the growing demand for phosphorus for agriculture. The chemical composition and mineralogy of aznekic phosphorites, as well as their role in the production of phosphorus fertilizers, are discussed. We analyze the main stages of the technological process, including the preparation, extraction and conversion of raw materials into phosphorus compounds. The available methods of obtaining phosphoric acid and phosphoric fertilizers such as superphosphate and ammophos are highlighted, as well as the economic and ecological aspects of the use of aznekic phosphorites in agronomy are considered. At the end of the article, it is emphasized the need to continue research and development of new technologies that will increase the stability of agriculture and increase the efficiency of resource use.
