Habka Socodka Dabiiciga Dhoobada Oksaydhka Copper Ee SX-EW

Summary: Daraasad ku samee socodka guud ee habka VTS-EW ee macdanta Nautī. Baro sida loo burburi karo, loo kiciyo leaching, loo qaato xal&nis, iyo electrowinning ay u keento naxaas nadiif ah oo 99.99% ah...

In siyaasadda hadda jirta ee qiimaha sare ee naxaasta iyo kheyraadka sulfide-ka heerka sare ee dhaca, kheyraadka naxaasta oksaydhku waxay u soo baxeen inay yihiin qayb muhiim ah oo ka mid ah soo saarista naxaasta aduunka. Habka Iskaashiga Soo saarista iyo Koronto-qaadista (SX-EW) ayaa marqaati ka noqday inay tahay habka ugu waxtarka badan uguna kharash yar ee lagu daweeyo macdanta naxaasta oksaydhka ah, iyadoo la siinayo ikhtiyaar hoose ee maalgashiga oo loogu talagalay waddooyinka caadiga ah ee birta lagu sii daayo. Qaab-dhismeedka socodka habkaani wuxuu sharaxayaa wareeg buuxa oo hydrometallurgical ah oo beddelaya macdanta naxaasta oksaydhka ah ee ceeriin ah una beddelaya naxaas ka mid ah cathode-ka heer sare ah, kaas oo gaaraya tayada alaabta oo ka badan 99.99% naxaasta ku jirta.

Qalabkan Hawlgallada nuxurka macdanta oksaydka naxaasta ee habka SX-EW waxaa loo habeeyaa afar nidaam oo weyn oo isku dhafan: the Nidaamka Cadaadinta, Nidaamka shiida, qodista, iyo sifeynta, Nidaamka Soo Saarista Xalka (SX), iyo Nidaamka Electrowinning (EW)Nidaam kasta waxaa loo qaabeeyey inuu si wadajir ah u shaqeeyo, isagoo hubinaya soo kabashada qadaadiicda naxaasta ee ugu badan, isticmaalka walxaha wax lagu daaweeyo ee ugu yar, iyo habka loo maareeyo deegaanka si masuuliyadi ku jirto.

Phase I: Qalabkan Nidaamka Cadaadinta – Preparing the Feed

Waxtarka guud ee warshadda ayaa ku bilaabma dhimista cabbirka ugu habboon.

• Burushka Hore: Macdanta run-of-mine (ROM) waxaa la galiyaa bakhida macdanta ceermiga ah, kadibna waxaa loo gudbiyaa qalbi-dhigayaal culus si loo yareeyo heerka koowaad ee wax soo saarka.
• Goynta Sare iyo Saddexaad: Alaabta la burburiyey waxaa lagu sifeeyaa shinnidyo xarig ah oo ku socda jiirada isku xiran ilaa mashiinka burburiyaha godka ah ee hal-cylinder ah. Kadib waxaa la raacaa nidaam wareeg ah oo xiran oo meesha ay marayso waliba shaandheyn gariir ah. Walaxda ka weyn waxaa lagu soo celiyaa burburiyaha godka ah ee saddexaad ee hal-cylinder ah si loo farsameeyo si cad, iyadoo la ilaalinayo xakameyn aad u fiican oo cabbirka ah.
• Xakameynta Deegaanka Agabka wax ku qalma ee hooseeya ayaa loo gudbiyaa jirka hoostiisa. Urban ka soo baxda inta lagu jiro wareegtadan waxaa qabta qashin ururiyeha boodhka ee pulse-jet baghouse kahor inta aan si nabad ah loogu sii deynin hawada, taasoo hubinaysa goob nadiif ah oo u hoggaansan sharciyada.

Faa'iidooyinka II: Nidaamka Goynta, Soo Saarista, iyo Sifeeynta

Si loo kordhiyo aagga dusha sare ee falcelinta kiimikada, macdanta la burburiyay waa in la yareeyaa si ay u noqoto dareere.

• Jawi-xidhka Guga-Xidhka Qalabka ka soo baxa weelka wareejinta waxaa loo gudbiyaa mashiinka kubbadda ugu weyn. Soo-saarka mashiinka ayaa gasha biyo-qadadka pulp-ka waxaana lagu duro classifier cycloon ah. Qeybta hoose ee cycloonka ayaa ku noqota mashiinka kubbadda, halka dhinaca sare ee qalabka laga xaaqo uu u gudbaa xaalad dhumuc leh.
• Qaybinta Dhiirrigelinta Qoyaalka hoose ee xaalka waxaa lagu caanibaa silsilad ceelal liin-bax ah, halkaas oo aashitada sulfuric uu ku dhex jiro. Dhaqdhaqaaqa xooggan ee lagu sameeyo wuxuu xaqiijinayaa in dhalaalida copper-ka ay si degdeg ah oo badan u dhacdo.
• Kala soocidda Waaxtada iyo Biyaha Biyaha la soo saaray ee laga saaray ayaa marinaya habka dhaqdaanka iyo shaandhaynta ka hortagga ah ee isticmaalaya nidaam shaandhayn taagto leh oo afar-heer ah oo ku yaal shabag vacuum toosan ah. Tani waxay si nadiif ah uga soocaysaa Xalka Faaruqinta Weynta leh (PLS) ee qiimaha leh iyo qalfoofka wasakhda. Qalfoofka ayaa si nabad ah looga saaraa goobta, halka PLS-ka hodanka ku ah dahabka uu gala badda xalka uurka leh.

Wajiga III: Nidaamka Jariiraha Macdanta Biyuhu (SX)

Waqtigan wuxuu cusbooneysiinayaa oo nadiifiyaa xal xoogaa daciif ah oo dahabka ah.

• Marxaladda Soo saarista: PLS waxaa lagu wataa mashiinka isku-dhiska oo isku-dhafka ah. Mashiinka isku-dhafka ah, PLS biyuhu si fiican ayaa loogu walaaqayaa wax-soo-saarka organic ee dhinaca labaad ee ka soo baxa qaadista ka soo horjeeda. Cuqdigu wuxuu ku xidhmayaa si gaar ah oo leh qaybta organic.
• Maareynta Raffinate Waqtiga haray ee xaaladda biyaha aan wax dhalin (raffinate) ayaa la caddeeyay si loo saaro waxyaabaha organic-ka ah ee ku dhex jiray loona tuuraa barxad kayd ah si dib loogu isticmaalo sida xal habka weelka lagu dhaqo, iyadoo la yareynayo isticmaalka asiidka iyo biyaha.
• Nadiifinta iyo ka saarida maqaarka (Scrubbing and Stripping) Faasaska organic-ka ah ee leh birta ah ayaa maraya hab kaliya oo nadiifin ah si looga saaro wasakhda, dabadeedna waxay u qulqulayaan taangiga kaydinta. Kadib waxaa lala xiriiriyaa xal sosoc ah oo asiid weyn leh heerka qalliin-ka nadiifinta. Tani waxay xoogga saareysaa in birta laga soo saaro dareeraha organic-ka ah una wareegto qaybta biyaha, taasoo keenta Advance Electrolyte nadiif ah oo heer sare ah oo diyaar u ah marxaladda ugu dambeysa.

Fasalka IV: Nidaamka Koronto-soo Saarista Electrowinning (EW)

Beddelka ugu dambeeya ee laga bilaabo dareeraha ilaa bir adag wuxuu ka dhacaa xanibaadda alaabta.

• Diyaarinta Unugga: Ul AA hore ee korontada waxay dhaaftaa qalabka kululaynta saxda ah ee shaandhada kulaylka si loo xakameeyo heerkulka ka hor inta aanay galin tanka madaxda. Ka dib waxay ku qulqulisaa cufnaanta dabiiciga ah unugyada polymer-ka electrowinning gaar ah.
• Rarid Kiimiko Koronto Gudaha unugyada, anoodooyin aan milmi karin (oo ka samaysan alloy ternary Pb-Ca-Sn) iyo katoodooyinka warqadda bilawga ayaa si sax ah loo kala fogeeyey. Koronto toos ah ayaa keenta in koperka uu ka baxo xalinta oo uu ku dhaco katoodooyinka.
• Goosashada Tombokta Ka dib markii wareeg cayiman uu dhamaado, xarigyada kore ee shabahada waxay soo qaadaan kaatoodooyinka la raran yahay waxayna u wareejiyaan weelka dhaqidda. Foorarka la dhaqay ayaa loo soo maraa mashiinnada goynta gaarka ah iyo mashiinnada laba jeer lagu simiyo si loo soo saaro wax soo saarka ugu dambeeya: naxaasta katoodo oo nadiif ah 99.99%, oo diyaar u ah in la baakado lana geeyo suuqyada caalamka.

Waddo la Tijaabiyey oo lagu Sii Wado Soo Saarista Qalabka Copper ee Nadiifsan

Habka SX-EW ee kor ku xusan wuxuu matalaa hab waayo-arag leh, lagu kalsoonaan karo, oo dhaqaale ahaan soo jiidasho leh oo lagu farsameeyo copper oxide. Marka la isku keeno burbura, shiidi, kala dheereyn, qaadashada xalalka, iyo koronto soo saarid, qaab-dhismeedkani wuxuu gaaraa dhowr yool oo muhiim ah:

• Soo kabashada Dhoobada Sareeya: Marxaladda xirnaanta wareega burburinta iyo shiidi doonta ayaa hubisa in cabbirka xumbada uu noqdo mid ku habboon daadsinta, iyadoo la adeegsanayo habka soo jiidashada ee lidka ah ee ku dhex jira silsiladda SX si loo kordhiyo waxtarka wareejinta dahabka.
• Tayada Alaabta: Isku darka soo saarista biyaha kala soocidda ah iyo koronto-taliminta la xakameeyo waxay soo saaraan koperat cathode oo buuxiya shuruudaha nadaafadda ugu sarreeya (99.99% Cu), ku habboon codsiyada ugu baahida badan.
• Waxtarka Hawlgalka: Recycle streams—such as raffinate return to the leaching circuit and organic phase reuse—minimize reagent consumption and reduce liquid effluent discharge.
• Mas'uuliyadda Deegaanka: Nidaamyada uruurinta boorka, halbawlaha xalalka gidaarka leh, iyo habraacyada maaraynta qashinka dambe waxay xaqiijinayaan in hawlgalka uu la jaanqaado qiyamka deegaanka ee casriga ah.

For mine owners and project developers evaluating oxide copper resources, the SX-EW process offers a proven pathway from ore to metal. With appropriate equipment selection and process design tailored to specific ore characteristics, this flow sheet can be adapted to operations of varying scale—from small, high-grade deposits to large, low-grade bulk tonnage projects.

Maaddaama baahida copper-ka ay sii kordheyso oo warshaddu ay si badan ugu jeeddo ilo oksayd ah si ay ugu darto wax-soo-saarka sulfide-ka, habka SX-EW ayaa ah tignoolajiyada doorbidaya ee wax-soo-saarka copper-ka ee hufan, qiimo-ool ah, isla markaana deegaan ahaan waxtar leh.
