Problems solved by technology

[0003] The iron ore is roasted in the roaster, which causes multiple pollution of dust and water, steam and dust on the production site. Because there are many acidic substances in the water, steam and dust, the corrosion of the site equipment is very serious, and it causes great pollution to the environment.

[0025] Iron ore high temperature treatment methods, including:

[0026] Step 1. Grind the rough iron ore until the particle size is not greater than 4mm, rinse with water until it is wet, turn the rough iron ore, blow hot air into the gap between the rough iron ore, make the surface temperature of the rough iron ore reach 30°C, and stop blowing hot air , dehumidify to make the relative humidity reach 50%-60%, rinse the rough iron ore with acetone until wet, turn the rough iron ore, blow hot air into the gap between the rough iron ore, and make the surface temperature of the rough iron ore reach 60°C, Stop blowing hot air, dehumidify to make the relative humidity reach 50%-60%, rinse the rough iron ore with ethanol until it is wet, turn the rough iron ore, blow hot air into the gap of the rough iron ore, and make the surface temperature of the rough iron ore When it reaches 90°C, stop blowing hot air, dehumidify to make the relative humidity reach 50%-60%, and obtain the iron o...

Abstract

The invention discloses a high-temperature treatment method of iron ore. The high-temperature treatment method comprises the steps that step1, crude iron ore is leached to be wet by water, the crude iron ore is turned, and hot air is blown into gaps of the crude iron ore; step 2, the iron ore after primary purification obtained in the step 1 is slowly heated; and step 3, the iron ore after secondary purification obtained in the step 2 is slowly cooled, and compound solution is sprayed onto the surface of the iron ore to obtain refined iron ore. The high-temperature treatment method can effectively remove sulfur impurities in the iron ore in stages, the structure is simple, the functionality is high, and the market promotion value is large.

Description

technical field [0001] The invention relates to the field of development and utilization of iron ore. More specifically, the present invention relates to a method for high-temperature treatment of iron ore. Background technique [0002] In recent years, with the rapid development of the iron and steel industry, my country has intensified the development of iron ore resources, and the resources of high-grade and good-sorting iron ore resources are gradually decreasing, and the supply capacity of mineral resources continues to decline. Actively developing difficult-to-use iron ore resources can effectively expand my country's available iron ore resources, reduce foreign dependence, and ensure the security of iron ore supply. [0003] The iron ore is roasted in the roaster, which causes dust and multiple pollution of water, steam and dust on the production site. Because there are many acidic substances in the water, steam and dust, the corrosion of the on-site equipment is ver...
