Hanyar dawo da karafa masu mahimmanci daga ruwan acidic ta amfani da shi Sodium hydrosulfide yana da babban farfadowa da fa'idodin tattalin arziki. Tsarin ya ƙunshi matakai masu zuwa:

01.Babban Tankin Adana Ruwa

Ruwan acidic da aka samar yayin aikin hakar ma'adinai ya fara fitowa daga babban tankin ajiyar ruwa zuwa cikin tankin cire baƙin ƙarfe na farko, inda aka ƙara lemun tsami. Ƙwayoyin ƙarfe masu trivalent a cikin ruwan acidic suna hazo tare da calcium sulfate, kuma yawancin ions na baƙin ƙarfe suna cirewa daga ruwan acidic.

02. Tankin Cire Karfe Na Farko

Ruwan amsa yana gudana daga tankin cire baƙin ƙarfe a cikin tanki na farko na degassing, inda aka ƙara flocculant.

03.Tsarin Cire Karfe Na Biyu

Danyen ruwan, wanda aka gauraya sosai da slurry na lemun tsami da flocculant, yana kwarara cikin tanki mai kauri, inda iron hydroxide da calcium sulfate ke tsirowa zuwa kasan tanki mai kauri.

04. Tankin Degasing na Farko

Ruwan acidic wanda ke ɗauke da ions ƙarfe masu mahimmanci, wanda aka cire adadi mai yawa na ion ƙarfe trivalent, yana gudana ta hanyar nauyi zuwa cikin injin ƙarfe sulfide reactor.

05.Metal Sulfide Reactor

A cikin karfe sulfide reactor, ruwan acidic yana haɗe sosai da ƙarfe sulfide precipitate da sodium hydrosulfide, yana haifar da barbashi sulfide.

06. Tankin Degas na Biyu

A gauraye ruwa dauke da karfe sulfide maida hankali gudãna da nauyi a cikin na biyu degassing tanki manne da karfe sulfide reactor, inda wani flocculant da aka kara inganta agglomeration na karfe sulfide barbashi zuwa manyan barbashi.

07.Karfe Sulfide Tank mai kauri

Ƙarfe na sulfide da aka tattara ya daidaita zuwa kasan tanki mai kauri na sulfide na ƙarfe. Sraper yana cire tsattsauran hazo zuwa tsakiyar kasan tanki mai kauri. Famfu na reflux yana ci gaba da sake yin amfani da wani yanki na hazo daga kasan tanki mai kauri yana komawa zuwa tankin cire baƙin ƙarfe, yayin da sauran hazo ana aika da shi zuwa tarin dutsen sharar gida ta famfo mai isarwa.

08.Karfe Sulfide Tank mai kauri

Famfu na zagayawa yana ci gaba da sake yin amfani da wani yanki na hazo daga kasan tanki mai kauri na sulfide zuwa karfen sulfide reactor. Ana aika da ɗayan ɓangaren hazo na ƙasa zuwa faranti-da-frame tace latsa don a mai da hankali cikin ma'aunin sulfide na ƙarfe.

Amfanin hanyar dawo da karafa masu mahimmanci daga ruwan acidic ta amfani da sodium hydrosulfide sune kamar haka:

Maido da karafa masu mahimmanci kai tsaye daga ruwan datti na acidic da ma'adinai ke samarwa ya kai kusan rabin hanyoyin sarrafa ma'adinai na gargajiya. Matsayin sulfides masu mahimmancin ƙarfe da aka gano ya kusan ninki biyu na hanyoyin sarrafa ma'adinai na gargajiya, tare da babban farfadowa da fa'idodin tattalin arziki. Ruwan datti bayan farfadowa ya ƙunshi ƙananan ions ƙarfe masu nauyi, wanda ke haifar da ƙananan farashin maganin ruwa da kuma fa'idodin muhalli masu kyau
