Embodiment 1
[0033] Firstly, the rhenium concentrate is mixed with water according to the solid-to-liquid ratio of 1:4, and the rhenium concentrate is low in copper and high in arsenic. The composition of the rhenium concentrate is shown in Table 1:
[0034] Table 1 Composition and material quantity data table of rhenium concentrate
[0035]
[0036] Add 300kg of quicklime to adjust the pH to 14, then add 2099kg of hydrogen peroxide, the amount of hydrogen peroxide added is 5.71 times the dry weight, and then add 72kg of quicklime to adjust the pH to 14 to obtain the decontamination residue and decontamination solution. The ingredients are shown in Table 2 and Table 3:

Embodiment 2
[0044]Firstly, the rhenium concentrate is mixed with water according to the solid-to-liquid ratio of 1:3, and the rhenium concentrate is low in copper and high in arsenic, and the amount of material is reduced. The composition of the rhenium concentrate is shown in Table 4:
[0045] Table 4 Composition and material quantity data table of rhenium concentrate
[0046]
[0047] Add 223kg of quicklime to adjust the pH to 14, then add 1356kg of hydrogen peroxide, the amount of hydrogen peroxide added is 5.50 times the dry weight, and then add 50kg of quicklime to adjust the pH to 14 to obtain the decontamination residue and decontamination solution. The ingredients are shown in Table 5 and Table 6:

Embodiment 3
[0055] Firstly, the rhenium concentrate is mixed with water according to the solid-to-liquid ratio of 1:5, and the rhenium concentrate is high in copper and low in arsenic. The composition of the rhenium concentrate is shown in Table 7:
[0056] Table 7 Composition and material data table of rhenium concentrate
[0057]
[0058]
[0059] Add 297kg of quicklime to adjust the pH to 14, then add 2130kg of hydrogen peroxide, the amount of hydrogen peroxide added is 5.92 times the dry weight, and then add 70kg of quicklime to adjust the pH to 14 to obtain the decontamination slag and decontamination solution. The ingredients are shown in Table 8 and Table 9:
