The baƙin ƙarfe mu yi amfani da yau zo daga teku cewa wanzu kusan biliyan biyu da suka wuce da aka teaming tare da narkar da baƙin ƙarfe. Lokacin da na farko kwayoyin iya photosynthesis fara sakewa oxygen a cikin wadannan baƙin ƙarfe-arziki jikin ruwa, baƙin ƙarfe fara kafa kamar yadda adibas a Duniya ta ɓawon burodi, wanda yake nufin shi ne da farko samu a sedimentary kankara.
Ores dauke da high yawa daga magnetite (wanda ya ƙunshi game da 72% iron) kuma hematite (wanda ya ƙunshi game da 70% iron) aka sani da suna "halitta" ko "kai tsaye shipping" ores. Wadannan kayan iya tafiya kai tsaye zuwa ƙarfe yin Tanderu domin samar da karfe.
Duk da haka, tun da tama adibas da aka nitsewa a teku bene biliyoyin shekaru da suka wuce gauraye a tare da wasu abubuwa da kuma ma'adanai, baƙin ƙarfe ne sau da yawa samu a abin da ke da aka sani da hada baki da baƙin ƙarfe tsarin. Wadannan kullum dauke da wani yawa ƙananan taro na baƙin ƙarfe gauraye a tare da silicates, oxides, kuma a wasu lokuta carbonates. Yin ilimin lissafi, pulling one ton of Karafa from banded formations creates up to three tons of tailings.
Duk da yake yana da gaskiya cewa da baƙin ƙarfe ne na huɗu ya fi na kowa kashi samu a wannan duniya tamu ta surface (bayan oxygen, silicon, da aluminum), ton na shi ne m ana "jefa tafi" saboda shi ke ba da ake yadda ya kamata cirewa. A lokacin, akwai ba ze zama mai kasawa na baƙin ƙarfe a duniya. Duk da haka, mining does have an environmental impact. Kuma tailings da aka generated da rigar Magnetic da flotation dabaru bukatar sabo ruwa kafofin, and require the introduction of expensive and potentially toxic chemicals that must be stored until decontaminated.
ST Boats & Technology yana da mafita mafi kyau. Our triboelectrostatic bushe rabuwa tsari za a iya kara kau tama daga sharar gida kõguna, kawar da buƙata domin a sabo-ruwa Madogararsa, kudi na flotation sunadarai, da kuma gina rigar aiwatar tailing tafkunan. Babu decontamination zama dole.
This separator is environmentally friendly because it doesn’t use a lot of energy, but it can process a high volume of material quickly to increase your output—not only iron ore, amma wani m abubuwa da za su iya zama a cikin tailings ciki har da jan, nickel, da kuma cobalt. Bugu da kari, the separator can be used at your mining site so there’s no need or expense for shipping materials to a facility for sorting.
