COMPARISON OF CHILEAN NATURAL PHOSPHATIC MINERALS

The begining of phosphatic deposits study was dated around 1963 through the survey developed at Bahia Tongoy, and later on at Pachingo in 1989. In this article, a synthesis of the main geological, physico-chemical, and agronomic features of these materials is presented, remarking some of these prope...
