Enrichment of Low-Grade Phosphorites with Organic Acids: Selective Leaching and Sustainable Processing of Low-Grade Phosphorites

Monograph presents a detailed exploration of innovative technologies for processing and upgrading low-grade phosphorites using organic acids. The book offers a comprehensive analysis of the selective leaching process, optimizing parameters such as temperature, pH, and acid concentration to maximize efficiency. It also includes experimental data on the structural and chemical changes in phosphorite materials during treatment, supported by advanced characterization techniques. Practical case studies demonstrate the environmental benefits of these sustainable methods, making this work an invaluable resource for researchers, industry professionals, and graduate students seeking modern, eco-friendly solutions for phosphate enrichment.
