Pali mitundu yambiri yosiyanasiyana ya Iron Ore Beneficiation Technology kupezeka. Aliyense ali ndi ubwino ndi kuipa kwake ndipo aliyense amagwiritsa ntchito njira yosiyana kuti akwaniritse zotsatira zomwezo. Nkhani iyi, cha ku Switzerland Zida & Technology (STET), adzakuyendetsani mumayendedwe aukadaulo wosiyanasiyana wachitsulo.
Pali njira zitatu zazikulu zopangira chitsulo - migodi, processing, ndi pelletizing. Mining is the process of taking zitsulo kuchokera padziko lapansi; kukonza ndikuchotsa zinthu zonse zopanda pake (gange). Kupeza kalasi yeniyeni ya mankhwala ndi ma pelletizing ndikusandutsa zinthu zokonzedwa kukhala zazing'ono, chogwiritsidwa ntchito. adzakuyendetsani mumayendedwe aukadaulo wosiyanasiyana wachitsulo.
Madipoziti achitsulo akachotsedwa pansi, ziyenera kukonzedwa kuti ziwonjezere chitsulo ndikuchepetsa kuchuluka kwa mchere wa gangue. Chigawo chilichonse chili ndi mankhwala ake apadera. Pofuna kupanga chitsulo chogwiritsidwa ntchito (Fe), mchere wina ayenera kuchotsedwa mu miyala. Maminolo ena omwe amatha kuwononga chitsulo ndi silika- ndi mchere wokhala ndi aluminiyamu monga quartz, kaolinite, gibbsite, diaspore, adzakuyendetsani mumayendedwe aukadaulo wosiyanasiyana wachitsulo.
Zida zamakono zolekanitsa zimalola kuti chitsulo chotsika kwambiri chisinthidwe kukhala chitsulo chapamwamba kwambiri. adzakuyendetsani mumayendedwe aukadaulo wosiyanasiyana wachitsulo.
Mkati monyowa kupindula kwa iron ore luso, pali njira zingapo zosiyana. adzakuyendetsani mumayendedwe aukadaulo wosiyanasiyana wachitsulo.
asamire nthawi zambiri amagwiritsidwa ntchito limodzi ndi kupatukana kwa maginito. Njirayi imagwiritsa ntchito mankhwala opangira mankhwala omwe amachititsa kuti chitsulo chigwirizane ndi zomwe zimachitika ndikuzilekanitsa ndi zipangizo zina. Kuwonjezera pa kugwiritsa ntchito mankhwala, madzi amafunikira kuti zitsimikizire kuti zimagwira ntchito bwino. Zotsatira zake, madzi otayira ambiri amapangidwa ndipo kuyeretsa madzi kumafunika. Mofananamo, pofuna kuonetsetsa kuti tinthu tating'ono tating'ono ting'onoting'ono tapatukana ndi chitsulo, kufotokoza ndikofunikira. Komabe, adzakuyendetsani mumayendedwe aukadaulo wosiyanasiyana wachitsulo.
Kupatukana Kwamaginito Konyowa (Low Intensity ndi High Intensity) Ndi njira yonyowa yamaginito yolekanitsa zitsulo zachitsulo zimayikidwa mu ng'oma yokhala ndi maginito ndipo madzi amaponyedwa mmenemo kuti athandize kulekanitsa zipangizo.. Kutengera kapangidwe kazinthu mu ng'oma, mphamvu yotsika kapena yayikulu kwambiri ya maginito ingagwiritsidwe ntchito kulekanitsa tinthu tating'onoting'ono.. kachiwiri, madzi otayira amapangidwa ndipo kuthira madzi kumakhala kofunikira.
Mkati kulekana kwachitsulo chowuma, zilipo a njira zochepa zomwe zingagwiritsidwe ntchito. Amaphatikizapo kulekanitsa mphamvu yokoka, kugawanika kwa maginito owuma, ndi STET youma electrostatic kulekana.
Kupatukana kwa Mphamvu yokoka zimatengera momwe kuphwanyidwa ndi kukula kwa gawo la ndondomekoyo kudayendera. Ndi njira iyi, mphamvu yokoka imagwiritsidwa ntchito ngati mphamvu yaikulu yolekanitsa chitsulo ndi mchere wa gangue. Iron imakhala ndi mphamvu yokoka kwambiri kuposa mchere wina womwe umapezeka nawo, kotero ndi mphamvu yokoka, idzagwetsedwa pansi mofulumira kuposa mchere wina. adzakuyendetsani mumayendedwe aukadaulo wosiyanasiyana wachitsulo.
Kupatukana kwa Magnetic kowuma kwenikweni n'chimodzimodzi ndi kunyowa maginito kupatukana kupatula ngati si ntchito madzi kuthandiza kutsogolera njira kulekana.. m'malo, imadalira kokha mphamvu ya maginito ya mchere kuti iwalekanitse wina ndi mzake. adzakuyendetsani mumayendedwe aukadaulo wosiyanasiyana wachitsulo.
STET Dry Electrostatic Leparation ndiye chida chabwino kwambiri cholekanitsira chitsulo chowuma chopezeka bwino, mwinamwake unrecoverable chitsulo miyala. adzakuyendetsani mumayendedwe aukadaulo wosiyanasiyana wachitsulo.
Pali zambiri ubwino ku kugwiritsa STET youma electrostatic kulekana. Mosiyana ndi njira zina zosiyanitsira chitsulo chowuma, kulekana electrostatic amalola kuti achire chindapusa chitsulo ore kuti akanatayika mu madera ochiritsira processing. Kuphatikiza apo, imalola kutsika mtengo kwa ndalama / zogwirira ntchito ndikupangitsa kuti chilengedwe chiwonongeke (kulola kulola kosavuta). Mofananamo, kulekana kwa electrostatic kumalepheretsa kufunikira kwa madzi, kugwiritsa ntchito mankhwala, ndi kuthetsa kusungirako / kutaya tailings yonyowa.
Mukuyang'ana njira ina yopezera chitsulo chopanda madzi? STET youma electrostatic kulekana ndi yankho lanu. cha ku Switzerland Zida & Technology (STET) imapereka kulekanitsa kwachitsulo chabwino kwa makasitomala padziko lonse lapansi. Gulu lathu la akatswiri ladzipereka kukuthandizani. Lumikizanani nafe lero ndi kuthetsa kusungirako / kutaya tailings yonyowa.
