While a 2015 definitive feasibility study targeted production of 4.1 Mtpa of phosphate concentrate with an unleveraged NPV of $1.85 billion with an IRR of 38%, Kropz believes a smaller-scaled project targeting production of 1-1.2 Mtpa can be developed initially for a significantly lower capital investment with similar returns.

The conventional phosphate beneficiation process. As mined, the phosphate and sand particles are embedded in compacted mud, or "clay-balls". Before separation can begin, all the particles must be liberated from the matrix of mud. The very first unit operation in the beneficiation process is to disaggregate the various particles; this ...
