FIELD: metallurgy.
SUBSTANCE: method is implemented by layer-by-layer leaching of the rhythmic-zonal ore particles - oolites of goethite-hydrogoethite composition with grain class -0.50+0.25 mm, being loose ironstone ore produced by method of hydraulic borehole mining. After leaching under percolation conditions two separate productive solutions are produced, i.e. iron-containing and containing phosphorous and rare-earth elements.
EFFECT: simple production of purpose products: iron powder, phosphorous and mineral fertilisers on its base, and strategic raw materials - rare-earth elements.
