Tsawg dua ob xyoos, Minnesota cov pellet tag nrho cov khoom lag luam tau poob mus rau 18 lab tons, raug US thiab kev lag luam thoob ntiaj teb poob. Nrog kev kaw ntawm cov ntoo pelletizing, qhov peev txheej txhua xyoo ntawm cov ntoo pelletizing yog ze li tsawg dua 40 lab tons.
Muaj rau tsob paj pelletizing hauv Northeast Minnesota. Cov ntaub ntawv raw yog los ntawm 130 mais ntev hlau ore strata. Nws yuav siv li peb thiab ib nrab tons ntawm hlau hlau los tsim ib tuj ntawm pelletizing.
Tsis tas li ntawd, tseem muaj cov thaj chaw uas tsis tau pom tseeb nyob hauv Xishan leeg, qhov uas muaj cov hlau oxidized (tsis yog hlau nplaum), uas nyuaj rau siv los ua pelletizing raw cov ntaub ntawv, kev siv zog loj thiab xav tau flotation.
Txhua xyoo, rau 6 tsob ntoo pellet thiab qhov project essarsteel nyob rau sab qaum teb yav qab teb Minnesota tshaj qhia rau Minnesota Lub Caj Meem Fai ntawm cov khoom siv hlau uas muaj peev xwm yuav khawb tau nyob hauv daim ntawv tso cai uas twb muaj lawm.

Ntawm lawv, mesabimetallics muaj 322 lab tons; keetac muaj 1,2 billion tons; hibbingtaconite muaj 153 lab tons; minntacmine muaj 674 lab tons; United taconite muaj 814 lab tons; cov duab tsho me me muaj 81 lab tons; Northshore Mining Co. muaj 835 lab tons.
Lub neej tsis zoo ntawm lub xeev cov mines yog kwv yees 16 xyoo rau mesabimetallics, 78 xyoo rau keetac, 6 xyoo rau hibbingtaconite, 14 xyoos rau minntacmine, 64 xyoo rau United taconite, 10 xyoo rau minorcamine thiab 62 xyoo rau Northshore Mining Co.
Minorcamine qhov project belongs rau cov tuam txhab ArcelorMittal; keetac project yog lub tuam txhab American steel.
