Dry extraction and purification of phosphate pebbles from run-of-mine rock |
| abstract |
This invention is an improved process for manufacturing pure phosphate pebbles from run-of-mine phosphate rock through a process of crushing, drying, disintegrating, separating and purifying. A secondary purification step comprising controlled disintegration, air classification and electrostatic separation is desirable in those cases where the run-of-mine rock used contains higher than the usual amount of iron and aluminum. |
