Abstract

The present invention provides a hydrometallurgy and separation method of rare earth ores. Leaching and neutralizing a sulfate roasted ore by a magnesium bicarbonate aqueous solution to remove impurities, and performing solid-liquid separation to obtain a magnesium-containing rare earth sulfate solution; performing extraction-transformation using P507 or P204 saponified by a magnesium bicarbonate aqueous solution or magnesium bicarbonate precipitation transformation and enrichment to obtain a mixed rare earth chloride solution having a high concentration, and then performing extraction separation and precipitation using a magnesium bicarbonate aqueous solution to recycle rare earths so as to obtain a plurality of rare earth compound products. Magnesium sulfate wastewater produced in the technical process above is subjected to alkali conversion by using a cheap alkali compound including calcium, magnesium and so on, and CO2 recycled in the hydrometallurgy and separation process is introduced to perform purification by carbonating so as to obtain a magnesium bicarbonate aqueous solution that is recycled and used in processes including leaching, transformation, extraction separation and precipitation of rare earths, thereby implementing cyclic utilization of magnesium and CO2, zero emission of ammonia nitrogen and wastewater, and greatly reducing production cost, improving the rare earth recovery rate and implementing green and environment-friendly, efficient and clean production of rare earths.
