It needs several requirements to achieve its full potential, the primary of which is the grain size, as we can't test gravity between a boulder and a gravel. The run-of-mine ore consists of sizes ranging from 2–3m diameter to fines, which is impossible to be processed by beneficiation, so there should be another process to treat.

Mining process. A large artificial freshwater pond is created in the dunes, on which floats the dredger and concentrator plant. While the dredge removes the material from the front end of the pond, the tailings generated by the separation process is stacked at the back; as a result the pond continuously moves in a forward.
