② Lokacin da sulfides da ke cikin ma'adinan sun ƙunshi ƙaramin adadin chalcopyrite, sphalerite, da galena ban da baƙin ƙarfe sulfide, zinare yana da alaƙa da pyrite da waɗannan sulfide masu nauyi.Tsarin jiyya na gabaɗaya: Dangane da tsarin al'ada da tsarin sinadarai na ƙarfe sulfide tama mara ƙarfe, kama kuma zaɓi abin da ya dace.Ana aika da hankali zuwa ga smelter don sarrafawa.Zinariya tana shiga jan ƙarfe ko gubar (yawanci ƙarin abubuwan jan ƙarfe) suna tattarawa kuma ana samun su yayin aikin narkewa.Bangaren da zinariya da baƙin ƙarfe sulfide ke zama symbiotic za a iya yawo don samun ƙarfin baƙin ƙarfe sulfide, wanda za'a iya dawo da shi ta hanyar gasasshen yanayi da leaching.

③ Lokacin da akwai sulfides masu cutarwa ga yanayi a cikin ma'adinai, irin su arsenic, antimony, da sulfide na sulfide, adadin sulfide da aka samu ta hanyar flotation dole ne a gasa shi don ƙone arsenic, sulfide da sauran karafa a cikin hankali cikin sauƙi Don ƙarancin ƙarfe oxides. , sake niƙa slag ɗin kuma yi amfani da alkalami don cire oxides na ƙarfe mara ƙarfi.

④ Lokacin da wani ɓangare na zinariya a cikin ma'adinan ya kasance a cikin 'yanci, wani ɓangare na zinariya yana da alama tare da sulfide, kuma wani ɓangare na gwal yana cikin ma'adinan gangue.Irin wannan ma'adinai dole ne a dawo da su tare da rabuwar nauyi don dawo da zinariya kyauta, da kuma dawo da symbiosis tare da sulfide ta hanyar hawan ruwa Don zinariya, dangane da abun ciki na zinariya na wutsiyar ruwa, yana da muhimmanci a yi la'akari da ko amfani da leaching sinadarai.Za a iya niƙa maƙarƙashiya mai laushi sannan a zube kai tsaye, ko kuma za a iya niƙa ragowar da aka kone bayan an kone su sannan a zube.
