Example Embodiment
[0014] Example 1
[0015] The present invention includes the following steps:
[0016] Step 1. Collect magnesium alloy scraps with a magnesium content of ≥85%. These magnesium alloy scraps mainly come from scraps produced in magnesium alloy processing, including but not limited to lump scraps, flake scraps, and fibrous scraps And granular waste;
[0017] Step 2. The magnesium alloy scraps collected above are pulverized by a metal pulverizer, which is required to be pulverized into pellets and flakes with a particle size range of 1-100 mesh;
[0018] Step 3. Use a vibrating sieve machine to screen the crushed scraps, among which 70g of large mesh scraps with a particle size of 40 mesh (about 0.43mm) are selected, and small meshes with a particle size of 60 mesh (about 0.25mm) are selected 30g scraps, mix them together, in the mixed scraps, the mass ratio of large mesh scraps to small mesh scraps is 7:3;
[0019] Step 4. In 1L of guar gum base liquid with a concentration of 0.4%, add 15...

[0037] Step 3. Use a vibrating sieve machine to screen the crushed scraps, among which 160g of large mesh scraps with a particle size of 10 mesh (about 2.00mm) are selected, and small meshes with a particle size of 40 mesh (about 0.43mm) are selected 40g scraps, mix them together, in the mixed scraps, the mass ratio of large-mesh scraps to small-mesh scraps is 8:2;
