METHOD OF RECOVERING AND EXPLOITING BLAST FURNACE DUST FROM IRON-SMELTING |
摘要 |
<p>A method of recovering and exploiting blast furnace dust from iron-smelting, comprising the following steps: ? Ore slurry production. ? Low-intensity magnetic separation, and then subjecting low-intensity magnetic separation tailings to gravity separation. ? Gravity separation, and then subjecting the gravity separation middlings and tailings to high-intensity magnetic separation. ? High-intensity magnetic separation: using a magnetic separator to perform high-intensity magnetic separation, and then pouring slurry into a flotation machine for roughing. ? Roughing, and then subjecting the roughing-produced froth to a first cleaning process, and then subjecting tailings from the roughing process to scavenging. ? Performing the first cleaning process, subjecting flotation-produced froth to a second cleaning process, and then subjecting flotation tailings to roughing. ? Performing the second cleaning phase, then concentrating, filtering, dehydrating, and drying the flotation-produced froth to produce carbon concentrate, and then sending the flotation tailings back through the first cleaning process. ? Performing the scavenging process: using a flotation machine to perform scavenging. ? Producing cemented fill material. The method enables the recovery and exploitation of blast furnace dust from iron-smelting without creating further emissions, and reduces the cost of dust processing.</p> |
