Abstract

A process for the extraction of rare-earth elements from phosphogypsum by its treatment with solution of ammonium carbonate, solving of the formed calcium carbonate sludge with nitrate acid. Calcium carbonate sludge is pulped with 10-20 % solution of calcium nitrate at ratio of solid phase and liquid, equal to 1:1(1:2, the obtained pulp is treated with 45-57 % nitrate acid at pH 5.7-7.1 with acid input velocity of 1.0-1.37 dm3/h to 1 kg of calcium carbonate.
