Le ndlela esetshenziselwe ukuqeda isikhumba se-oxide nokugqwala ebusweni bensimbi kusuka ezintweni zensimbi nensimbi, kusebenzisa izixazululo ze-acidiic, kuthiwani.
Ama-iron oxides anjenge-oxide scale kanye nokugqwala (Fe3o4, FE2O3, FEO, njll.) Bhekana namakhemikhali ngezixazululo ze-acid, kwakha amasawoti ancibilika kwikhambi le-acid futhi asuswe.
Hlala uphinde uphendule ngamakhemikhali ngezixazululo ze-acidic, okuholela ekwakhekeni kosawoti obuthabile okukhishwe ngemuva kwalokho. Ama-Acid kwinqubo yokukhulisa ehlanganisa i-sulfuric acid, i-hydrochloric acid, i-phosphoric acid, i-nitric acid, i-chromic acid, i-hydrofluoric acid, nama-acid ahlanganisiwe. Kaningi, i-sulfuric acid ne-hydrochloric acid zithandwa izinketho. Izindlela zokukhanyisa ngokuyinhloko zifaka ukukhetha kokucwilisa, ukukhahlela, kanye nokubheja ukugqwala kokugqwala.

Ngokuvamile, ukucwilisa ukucwilisa kuvame ukusetshenziswa, kanye nendlela yokufafaza ingasetshenziswa ekukhiqizeni inqwaba

Izingxenye zensimbi zihambisana nokuthathwa emhlanganweni ku-10% kuya ku-20% (ngevolumu) Isixazululo se-sulfuric acid ekushiseni okusebenzayo kwe-40 ° C. Ukufakwa esikhundleni kwesisombululo sokukhamba kuba ukufana lapho okuqukethwe kwe-iron kudlula i-80g / l kanye ne-ferrous sulfate kudlula i-215g / L kwikhambi.

Emazingeni okushisa ekamelo,ukugoqa insimbiNge-20% kuya ku-80% (ivolumu) I-Hydrochloric acid Solution ayithambekele ekugqwaneni kanye ne-hydrogen emflittlement.
Ngenxa yokuthola ukuqina okukhohlisiwe kwama-acid ansocis abheke ezinsimbi, kwethulwa ama-inhibitors ahlanzayo. Ukuhlanza ngemuva, ingaphezulu lensimbi libonisa ukubukeka okumhlophe kwesiliva, ngasikhathi sinye senzelwa ukwengeza izimfanelo zokumelana nokugqwala kwensimbi engenasici.

Ukwethemba lokhu okucacisiwe kufakazela okunenzuzo. Uma kuvela eminye imibuzo, ngicela ungangabazi ukuxhumana.
