PROCESS OF NODULIZING PHOSPHATE ROCK

As is well understood in this art, this problem increases considerably when using a high grade of phosphate rock. Thus, a large amount of fines are produced along with relatively large nodules or "clinks." It is necessary to reduce the size of the larger nodules, which produces additional fines, and it is also necessary to remove the fines and recirculate all of them back into the kiln. This

Challenges in Processing Phosphates

The phosphate rock becomes dusty upon drying, and fines are commonly collected in a baghouse. While these collected fines are dusty and difficult to handle, opportunity exists in agglomerating the fines so they are more easily handled and processed down the line. The agglomeration of fines significantly reduces issues associated with dust, and also allows the product to be more easily
