Embodiment Construction
[0007] Industrial pure water dissolves the rare earth chloride raw material and the reactant ammonium bicarbonate separately, and adds an acid co-reactant (such as: hydrochloric acid, silicic acid, sulfuric acid, etc.) to control the pH value of 3.5-4; When the alkaline reactant ammonium bicarbonate is processed, the concentration of the alkaline reactant is controlled at 10%-35%. The concentration of the dissolved rare earth raw material REO (total amount of rare earth) is controlled at 120-160 g / L, filtered, and added to the parent compound preparation device ∮ 2000-8.5, heated and stirred with steam, and the temperature is controlled between 30°C-60°C , add hydrofluoric acid, when the amount of hydrofluoric acid in the parent compound preparation device ∮ 2000-8.5 reaches 6.5-8% of the total amount of REO in the preparation device, the hydrofluoric acid injection is completed; to the parent compound preparation device Add dispersant and ammonium bicarbonate, control the sti...
