A process for making slow-release phosphate fertilizer from low-grade rock phosphate and siliceous tailings by fusion [1]

Worldwide demand of phosphate fertilizer is met essentially
from phosphatic rocks. India imports most of its requirements and produces a small portion through froth flotation of Precambrian stromatolitic rock phosphate. Increasing population and consequent increase in demand for food production necessitated investigation to utilize the large reserves of low-grade rock phosphate to produce an alternative fertilizer. An
acceptable phosphate fertilizer was obtained by fusion of low-grade dolomitic and siliceous rock phosphate from Jhamarkotra mines, effluents from beneficiation plants of Jhamarkotra and Maton Rock Phosphate Projects and serpentinite rejects from Rikhabdev d
