Example Embodiment
[0017] Example 1:
[0018] Embodiments of the present invention include:
[0019] A method for recovering and extracting rare earth oxides from neodymium iron boron waste, consists of the following steps:
[0020] (1) The first step: crushing, the neodymium iron boron waste is crushed by a crusher, the size of the crushed particles is 1cm 2 ;
[0021] (2) The second step: Incineration, the NdFeB waste crushed in (1) is incinerated at a high temperature, and the incineration product is obtained after incineration, which is turned once every 15 minutes during incineration, and the incineration temperature is 1,400 degrees Celsius;
[0022] (3) The third step: cleaning, the incineration products in step (2) are collected and rinsed with clean water to obtain clean cleaning materials, and the number of cleaning times is 3;
[0023] (4) The fourth step: acid dissolving, the cleaning material in step (3) is mixed according to the ratio of cleaning material and acid 1:1, and then dilute acid is...
