Abstract

The article presents the results of generalization of known information on various methods of enrichment of low-grade phosphate raw materials in the world. Based on the review of literature materials, scientists propose several methods of enrichment: mechanical, calcination at high temperatures, flotation, chemical enrichment with various acids and salts. Analyzing and summarizing these data, the article describes the advantages and disadvantages of each proposed method of enrichment of low-grade phosphorites. It is known that the sphere of production of phosphorus-containing products is important for many agricultural countries that produce these products themselves or import from others. This review material is very important for those who are interested in the problems of attracting low-grade phosphates into the production cycle by enriching them.
