Abstract—The components of the pyrochlore–monazite ore of the Tomtor deposit are separated by segregation and reduction smelting. Upon segregation smelting, rare-earth metals are found to concentrate in a phosphate–salt melt and niobium, in a silicate melt. The chemical compositions and the microstructures of the silicate and phosphate–salt melts are studied. Carbothermic reduction of the silicate melt at 1600°C results in the formation of an alloy with a high niobium content, and rare-earth metal oxalate and hydroxide concentrates can be formed from the phosphate–salt melt by sequential processing by various acids. A technological scheme is proposed for combined processing of the pyrochlore–monazite ore of the Tomtor deposit.
