Water magnetic iron selection machine and its use method Description: Water magnetic iron selection machine and its use. Belonging metallurgical processing methods and processing machinery. In order to solve the problem that the iron content in the industrial sulfuric acid waste residue has no good use, it has caused problems such as pollution. The method uses the magnet to attract the iron coloring in the sulfuric acid waste residue; the remarkable effect of extracting the iron component after the rapid demagnetization of the non-magnet field, achieving the raw material cost of only 2% to 3%, and then inputting 20% ​​to 40% of the water. The cost of magnetically selected iron production reaches 100%. It can greatly reduce pollution such as air, environment, surface and groundwater. It has the added social and economic benefits and mitigates the significant improvement of corporate and public public hazards.
Iron ore fines processing method dephosphorization Description: This process is an iron, iron powder dephosphorization treatment, can effectively solve the iron ore fines can not be too high phosphorous refining The problem of iron use, the technical solution to solve is to pulverize high-phosphorus iron ore and iron fine powder into coarse particles, put them into a dephosphorization vessel, and then add an equal volume of dilute hydrochloric acid solution to heat, at 55-75. After reacting at °C for 25-40 minutes, the hydrochloric acid solution is filtered off and rinsed with water. The method is simple, easy to operate, low in cost, good in dephosphorization, and can effectively solve high phosphorus-containing iron ore and iron fines. The problem of iron making of powder has created the necessary conditions for the exploitation and utilization of high-phosphorus iron ore, and provided abundant raw materials for the iron-making industry and opened up a vast world.
Steel slag iron powder production process Description: This method discloses a steel slag iron powder production process, the steel slag is dried by a tumble dryer, so that the steel slag water content is less than 1.5%, the dried steel slag is sent Into the electromagnetic pre-magnetizer for pre-magnetization, and then sent to the homogenization library for homogenization, storage, and then dry-type grinding, separating the granular steel of 3 mm or more and the steel slag powder of less than 3 mm, and then 3 mm or less The steel slag powder is selected by the powder separator for wind power selection, so that the steel slag powder is divided into two grades of particles larger than 180 mesh and less than 180 mesh, and the particles larger than 180 mesh are placed in a double cylinder dry permanent magnet magnetic separator for ferromagnetic separation and magnetic separation. After the steel slag powder is demagnetized by the electromagnetic demagnetizer to reduce the specific susceptibility of the steel slag powder, the magnetic agglomeration is released, and the demagnetized steel slag powder is sent to the ball mill for fine grinding to below 180 mesh. The steel slag iron powder and the steel slag fine powder are separated. The method has the advantages of low production process cost and no pollution to the environment.
Method for producing iron concentrate powder from pyrite ore and content thereof: Brief introduction: A method and device for producing iron concentrate powder from pyrite ore, which is based on the existing sulfuric acid plant, and increases the raw material compounding system. The slag discharged from the boiling furnace 3 is incorporated into pyrite as a raw material. The slag is discharged through the slag discharge pipe 3-4, discharged to the slag conveyor 5, sent to the humidifier 6, and then sent to the raw material field by the slag discharge belt 7, and mixed into the pyrite according to the calculated proportion, and fully mixed with The raw materials are put into the furnace, and then the raw materials are introduced into the furnace device 2, and calcined in the furnace. In addition to sulfuric acid, the obtained product can also obtain iron fine powder having a percentage of iron content of ≥63%. The use of short and economical methods to obtain huge economic benefits, open up new ways for the deep development of pyrite, and make greater use of pyrite resources to improve the economic benefits of existing sulfuric acid plants. Suitable for improvement and improvement of existing sulfuric acid plants.
Process based on extracting iron concentrate from industrial iron tailings: This method discloses a process based on extracting iron fines from industrial iron tailings, first immersing and cleaning industrial iron tailings in water Then, the cleaned tail ore is sent to the mill for crushing, and then the obtained ore is transported to a frequency of 50 Hz. The high-frequency screen with a voltage of 220V is screened, and the selected ore powder is sent to the wet permanent magnet roller type spinning machine for magnetic separation. Finally, the primary qualified ore powder is sent to the purifier for final purification; The process can be used to maximize the utilization of iron resources in industrial tailings, and the economic and social benefits are very obvious.
