phosphate rock comminution circuit

MEI Blog: New Book- Beneficiation of Phosphate OreBeneficiation of Phosphate Ore, by S. Komar Kawara and J.T. Carlson, examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric acid. The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum (calcium sulfate dihydrate).Designing Crushers with a Multi-Objective Evolutionary ...comminution is to transform raw ore into a more usable or more saleable product or to prepare it for further processing. A "comminution circuit" consists of a collection of processing units (crushers, screens etc) connected together (by conveyor belts, for example), possibly containing loops (hence the use of the word "circuit").
