Abstract
The invention discloses a method for extracting beryllium concentrates from uranium-leached tailings containing bertrandite. The method comprises the following steps: adding a sodium hydroxide solution into the uranium-leached tailings, and adjusting the pH value of ore pulp to 7; grinding ores until the content of the -200-mesh ores is more than 50 percent, stirring the ore pulp, adding sodium carbonate, and adjusting the pH value of the ore pulp to 10-10.5; stirring the ore pulp, and sequentially adding sodium fluoride, sodium sulfide, hydroximic acid and oleic acid; then stirring the ore pulp, filling air, and collecting foam products, wherein the foam products are the beryllium concentrates. The method is simple in flow, beryllium resources can be recovered from the tailings, and the utilization rate of the resources is improved.
