| titleOfInvention | Method for recovering chromium from ferronickel smelting slag and preparing light heat-insulating material by microwave reinforcement |
| abstract | The invention discloses a method for recovering chromium from ferronickel smelting slag and preparing a light heat-insulating material by microwave reinforcement. Taking the fine ferronickel smelting slag powder as a raw material, taking sodium nitrite and sodium peroxide as additives, and controlling the mass ratio of the ferronickel smelting slag to the sodium nitrite to the sodium peroxide to be 1: (0.2-0.4): (0.3-1.2), uniformly mixing the fine powder of the ferronickel smelting slag with sodium nitrite and sodium peroxide, roasting by microwave, leaching roasted materials by microwave-assisted water, and filtering to obtain chromium-containing leaching liquor and leaching slag. And (3) uniformly mixing the leaching residue with humic acid and water, pressing, forming, drying and roasting by microwave to obtain the light heat-insulating material. The method can realize the selective recovery of chromium in the ferronickel smelting slag and the efficient value-added utilization of the leached slag, and has the advantages of high production efficiency, environmental protection, high product added value and the like. |
