Obstaja veliko različnih vrst tehnologija za uporabo železne stene Razpoložljivih. Vsak ima prednosti in slabosti in vsak uporablja drugačno tehniko za doseganje enakega rezultata. Ta članek, ST opreme & Tehnologija (STET), vas bo pospremil skozi značilnosti različnih tehnologij za uporabo železne.
Obstajajo trije glavni koraki za proizvodnjo železne rude – rudarstvo, Predelavo, in peletizacijo. Mining is the process of taking železove rude z zemlje; obdelava odstranjuje vse neurabne materiale (gangue). Doseganje posebne stopnje kemijske sestave in peletizacije je spreminjanje predelanih materialov v majhen, enota, ki se uporablja. Predelava železne stene je najpomembnejši korak pri proizvodnji peletov in uporabljene so bile in razvite številne različne tehnike.
Once deposits of iron ore are extracted from the ground, they must be processed in order to increase the iron content and decrease the concentration of gangue minerals. Each deposit has its own unique chemical properties. In order to create a usable amount of iron (Fe), other minerals must be removed from the ore. Other minerals that can taint the iron ore are silica- and alumina-bearing minerals such as quartz, kaolinita, gibsit, diaspore, and corundum.
Separation technology equipment allows fine low-grade iron ore to be processed into much higher-grade iron ore. The different types of separation technology equipment fall into two main categories—wet and dry iron ore separation.
Within wet iron ore beneficiation technology, there are a few different techniques. This includes flotation and different intensities of wet magnetic separation.
Flotata is often used in conjunction with magnetic separation. This process uses a chemical reagent that causes the iron to adhere to the reaction and separates it from the other materials. In addition to the use of chemicals, water is needed to ensure the reaction works properly. Zaradi tega je, a lot of wastewater is created and water treatment is needed. Podobno, in order to ensure some of the finer particles separate from the iron, desliming is needed. Vendar, desliming can result in the loss of the iron particles as well.
Wet Magnetic Separation (Low Intensity and High Intensity) With a wet magnetic separation technique the iron ore deposits are placed into a magnetically charged drum and water is pumped into it to help separate the materials. Glede na sestavo materialov v bobna se lahko magnetna sila nizke ali visoke intenzivnosti uporabi za ločevanje delcev. Spet, se ustvarjajo odpadne vode in postane potrebna obdelava vode.
Znotraj ločitev suhe železne stene, obstajajo nekaj tehnik ki se lahko uporablja. Vključujejo ločitev težnosti, suha magnetna ločevanje, in STET suha elektrostatična ločevanje.
Ločitev gravitacije je v veliki meri odvisna od tega, kako dobro je šlo drobljenje in velikost dela procesa. S to tehniko, gravitacija se uporablja kot glavna sila za ločevanje železa od gangu mineralov. Železo ima večjo gravitacijsko poteg kot drugi minerali, ki jih najdemo z, tako z gravitacijo, bo potegnil navzdol hitreje kot drugi minerali. Obstaja veliko različnih strojev, ki uporabljajo gravitacijo kot glavno metodo ločevanja.
Suha magnetna ločevanje je v bistvu enaka kot vlažna magnetna ločevanje, le da ne uporablja vode, da bi olajšala proces ločevanja. Namesto tega, se zanaša samo na magnetne lastnosti mineralov, da jih loči med seboj. Suha magnetna ločitev ni zelo učinkovita na finih delcih.
STET Suha elektrostatična ločitev je najboljša oprema za separacijo suhega železa, ki je na voljo za fino, sicer nepremočljive železne ole. Ta postopek uporablja negativne in pozitivne naboje železa, da ga loči od drugih mineralov.
Obstaja veliko Koristi za uporabo STET suha elektrostatična ločitev. Za razliko od drugih metod ločevanja suhih železovih, electrostatic separation allows for the recovery of iron ore fines that would otherwise be lost in conventional processing circuits. še več, it allows for lower investment/operating costs and causes minimal impact on the environment (allowing for easy permitting). Podobno, electrostatic separation prevents the need for water consumption, use of chemicals, and eliminates the storage/disposal of wet tailings.
