Phosphate Beneficiation

The beneficiation plant does this with equipment called "hydro-cyclones". Slurry from the washer is fed tangentially into the cyclone (a conical chamber) at a high G force. The slurry swirls around inside the cyclone until fines overflow the top of the chamber. Coarse sand and phosphate particles swirl to the bottom of the cyclone and exit.

Plant nitrogen assimilation and use efficiency

Abstract. Crop productivity relies heavily on nitrogen (N) fertilization. Production and application of N fertilizers consume huge amounts of energy, and excess is detrimental to the environment; therefore, increasing plant N use efficiency (NUE) is essential for the development of sustainable agriculture. Plant NUE is inherently complex, as ...
