I-slag yensimbi, njenge-slag yokugcina yemfucuza ekhiqizwa ukuncibilikisa insimbi, iqukethe izakhi zensimbi eziningi. Ngenxa yokuminyana kwayo okuphezulu kanye nokuminyana kwayo okukhulu, ayikwazi ukuthandwa futhi isetshenziswe embonini yokwakha. Imithombo yensimbi eyigugu ayikatholakali kahle, okuholela enanini elithile lemfucuza. I-slag yensimbi kufanele isetshenziswe kabusha futhi isetshenziswe kabusha ngenqubo ethile yokuhlukanisa i-magnetic, futhi ihlangabezane nezidingo zezinga le-powder iron elidingwa yizinto eziqukethe insimbi zokuncibilikisa isithando somlilo, ukuze i-slag yensimbi ikwazi ukusetshenziswa kabusha. Ingasetshenziswa kangcono ekwakheni.
Njengamanje, inqubo ethile yokuhlukanisa i-magnetic iyindlela engenzeka kakhulu, futhi kubalulekile ukukhetha imishini efanelekile ukuze kufezwe ukuhlukaniswa kwensimbi kanye nokubuyiselwa okuphumelelayo. I-slag yensimbi iyagaywa ukuze kutholakale ukuhlukana kwayo, bese kuthi ngokuhlukaniswa kwe-powder ore okomile emoyeni, i-feed ore, i-concentrate kanye ne-tailings kwamukelwa ngokulandelana, bese kuhlaziywa izinga lensimbi eliphelele ukuze kutholakale izinqubo nemingcele yemishini engcono kakhulu. Nikeza ukwesekwa kobuchwepheshe okufanele ekukhiqizweni kwangempela.
Izakhiwo ze-slag zensimbi
I-slag yensimbi yi-slag yemfucuza ekhiqizwa ngokusebenzisa i-lime ene-magnesium ephezulu, i-lime esebenzayo nezinye izinto ezisizayo zokuhlanza nokuphefumula umoya-mpilo enkambisweni yokwenza insimbi, ngakho-ke iqukethe i-iron oxide ephezulu, ngokuvamile engu-20%-40%, kanti okuqukethwe yi-FeO kungaphezu kwe-Fe2O3, okokuqala ngokuvamile kungu-15%-25%, kanti okwesibili kungu-5%-15%, kokubili okubonisa amandla okuzibamba abuthakathaka.
Imishini yokuhlola
Imishini yokuhlola isebenzisa i-FX0665 powder ore air dry magnetic separator ye-Huate Company, esetshenziswa kakhulu ekukhetheni i-magnetite ngaphambi kokugaya noma ukukhiqizwa kwe-concentrate efanelekile evela ku-magnetite ephuthiwe.

igobolondo elingezansi
Isimiso sokusebenza se-powder ore air dry magnetic separator siboniswe esithombeni. Amaminerali afakwa ebusweni besigubhu sikagesi nge-ore feeding port 3, kanti amaminerali kazibuthe afakwa ebusweni besigubhu sikagesi ... Amaminerali angewona amagnetic noma imizimba ehlangene engaxubile ayifakwanga emlonyeni we-tailings ngaphansi kwesenzo samandla adonsela phansi kanye namandla e-centrifugal, futhi iba yi-tailings noma i-ore ephakathi.
Ukusungula izinto ezintsha kanye nobuchwepheshe obuyisihluthulelo bokuhlukanisa amandla kagesi omoya owomile we-powder ore
1. I-feeder edlidlizayo isetshenziselwa ukondla, futhi amapharamitha e-feeder angalungiswa ukuze kufezwe ukondla okufanayo;
2. Uhlelo lwe-magnetic lusebenzisa i-multi-pole, i-angle enkulu yokugoqa (kufika kuma-degree angu-200-260), ukwakheka kwamandla aphezulu ensimu (3000-6000Gs), kanye nesakhiwo sesistimu ye-magnetic singashintshwa ngokuya ngezakhiwo zamaminerali ukuze kufezwe izinkomba zokuzuza ezifanele;
3. Ijubane eliqondile lesilinda lilungiswa ngaphakathi kuka-1-20m/s, futhi ijubane eliqondile elifanele lingakhethwa ngokuya ngohlobo lwetshe eliyigugu; isilinda senziwe ngezinto ezingezona ezensimbi futhi sifakwe idivayisi yokuxuba enozibuthe ukuze kuthuthukiswe izinga lokugxila;
4. Inesakhiwo esithile sommese womoya, idivayisi yokunciphisa umoya kanye nedivayisi yokususa uthuli (amapharamitha afanele angakhethwa ngokuya ngohlobo kanye nezidingo zenkomba yensimbi); ubuso besilinda bunikezwa idivayisi yokukhulula, engenza ukukhishwa okuhlanzekile kwe-concentrate kuhlanzeke;
Isihlukanisi sikagesi se-FX powder ore air dry magnetic sakhiwe kakhulu ngedivayisi yokudlulisa, isigubhu sokuhlukanisa ugesi, idivayisi yokufutha, idivayisi yokususa uthuli oludonswayo, idivayisi yokuqoqa i-sedimentation, njll. Amandla kazibuthe esigubhu sokuhlukanisa ugesi angama-3500Gs. , amandla kazibuthe, amandla e-centrifugal ajikelezayo, njll., ingafinyelela ukukhethwa kwangaphambilini okomile kwe-magnetite engu-0-5mm noma ithuthukise kakhulu izinga le-magnetite yempuphu ecolekileyo. Imiphumela eyinhloko yile elandelayo:
A. Ibanga elikhethiwe le-magnetite engu-0-5mm lingandiswa lisuka ku-10% liye ngaphezu kuka-40%. Lingasetshenziswa njengokulahla ngaphambi kokugaya, okungathuthukisa kakhulu izinga lokungena futhi kuthuthukise ukusebenza kahle kwesigayo.
B.Ibanga elikhethiwe le-magnetite ehlungwe kahle engu--74um kanye ne--45um lingandiswa lisuka ku-10% liye ngaphezu kuka-60%, futhi ukugxila okufanelekile kungatholakala ngqo ngokukhetha okomile.
Indlela yokuhlola kanye nokuhlaziya.
①Ukuhlaziywa kwezinto ezivamile kanye nokutholakala kwezinto zensimbi.
