Phosphate Ore Article about Phosphate Ore by The Free

Phosphate ores are worked by open-pit and underground-mining methods: friable phosphorites, such as those in the Baltic republics, are worked by geotechnological methods. Various methods for concentrating phosphate ores exist, and the selection of a particular method depends on the mineral composition and the structure and texture of the ore.
