Method for leaching beryllium in bertrandite type beryllium ore

The invention relates to the field of wet metal recovery, in particular to a method for leaching beryllium in bertrandite type beryllium ore. The method comprises the following steps that S1, beryllium ore is crushed through a crusher and subjected to fine grinding; s2, uniformly mixing the crushed beryllium ore with a dilute sulphuric acid solution according to a certain proportion, wherein the liquid-solid ratio is 1.5-3L/kg; the mass percentage concentration of the dilute sulphuric acid is 10%-25%; s3, the mixed ore pulp is leached under the pressure effect; and carrying out vacuum suction filtration on the reacted mixed solution, and separating a solid phase from a liquid phase to obtain beryllium-containing leachate and leaching residues. Under the condition that concentrated sulfuric acid is not used, beryllium leaching is achieved, the use amount of sulfuric acid is greatly reduced, meanwhile, the leaching temperature is reduced, and the production cost is saved. 本发明涉及湿法金属回收领域，尤其涉及一种浸出羟硅铍石型铍矿中铍的方法。所述方法
