Inqubo Yokugeleza kwesihlabathi se-Copper Oxide Ore SX-EW

Summary: Hlola yonke inqubo ye-Copper Oxide Ore SX-EW. Khetha ukuthi ukugaya, ukugcoba ngokushaya, ukuthatha isixazululo nokukhipha ngogesi kukhiqiza insimbi yensimbi ehlanzekile engu-99.99%...

Okwiwo lwamanje lwezintengo eziphezulu zikablue neziqongo eziphelayo zesifindo se-sulfide eziphezulu, izinsiza zikablue ze-oxide zivele njengengxenye ebalulekile yokukhiqizwa kwamazwe wonke kawolwe. Inqubo ye-Extraction ye-Solvent kanye ne-Electrowinning (SX-EW) ibonakale njengendlela esebenza kahle futhi ecishe ishaye zonke ezinye indlela ngezindleko zokwelapha izinsalela zikablue ze-oxide, ijwayele ukufinyeleleka okuphansi kwezimali uma kuqhathaniswa nezindlela ezivamile zokushisa. Lo mfanekiso wombhalo wenqubo uchaza umjikelezo ophelele we-hydrometallurgical owuguqula i-ore ye-oxide enezinsalela zikablue ukuze kube ikhabhoni yekhodi ephezulu, efinyelela izinga lomkhiqizo elidlula i-99.99% ukuphatha ikaboni.

I- Inqubo yokugeza i-oxide yothuli lwekhabhoni nge-SX-EW ihlelwe izinhlelo ezine ezinkulu ezihlanganisiwe: lezi Uhlelo Lokucindezela, Uhlelo Lokuqhekeka, Ukukhipha Izingcezu Nokuhlunga, Uhlelo Oluhlinzekwa Ngezixazululo (SX)Futhi Uhlelo lwe-Electrowinning (EW)Isistimu ngayinye ihlelelwe ukusebenza ngokuhambisana, iqinisekise ukutholwa okuphezulu kwekhabhoni, ukusetshenziswa okuncane kwe-reagent, nokucutshungulwa okuzuzisa imvelo.

Phase I: I- Uhlelo Lokucindezela – Preparing the Feed

Ukusebenza kahle kwazo zonke izitshalo kuqala ngezinga elifanele lokwehliswa kobukhulu.

• Ukucindezela Okuyinhloko: Igolide ye-ROM (Run-of-mine) ifakwa ebhokisini legolide elisha, ngokulandelayo ihanjiswa ngumfundi onamandla endaweni yokuhlafuna ukuze yenze ukwehliswa okukhulu okukuvamile.
• Ukuphahlazeka kwesibili nesesithathu: Umkhiqizo oqotshwe uthuthwa nge-conveyor belt uye ku-crusher yomgogodla owodwa wekhoni. Lokhu kulandelwa ukwenza uhlelo lokuvala indawo lapho izinto zidlula khona esibonakaliso esixakile. Izinto ezinkulu kakhulu zibuyiselwa ku-crusher yomgogodla wekhoni yesithathu ukuze zilukaniswe ngobumnene, kuqinisekiswe ukulawulwa kobukhulu obukhulu.
• ULawulwa Kwezemvelo: Izinto ezingaphansi kwesilinganiso esifanele ziphAthwa ziye ekhishini lomhlaba. Umswakama oluvelayo kulolu hlelo luthathwa ngumqoqi womoya onomoya ophaphayo onobhedaya obonakalayo ngaphambi kokuthi kuphumele kahle emoyeni, kuqinisekisa indawo ehlanzekile futhi ehambisana nemithetho.

Isigaba II: Uhlelo lokugaya, ukukhipha izinto, nokuhlunga

Ukuze kuthuthukiswe indawo yobuso bemizwa yezibalo ze-chemical, ithuli lemineral elihlutyiwe kufanele liphansi libe umxube.

• Ukuqothula Okwimanqamu Okuvalekile Into eyi-transfer ichithwa ibothi ukuze iqhubeke ngayo emshinini omkhulu wokugayi. Ukuphuma komshini kugreda uye ku-pulp sump futhi kuphonswa ku-classifier ye-cyclone. I-underflow ye-cyclone ibuyela kumshini wokugayi, kuyilapho i-overflow ethambile ibika ku-thickener.
• Ukuqhudelana Ngokuhlweyisa Ukuphuma kwesikhuhli okukhulu kuhlutshwa emathangeni ahlukahlukene wokuhlwaya, lapho kufakwa khona i-oyela kawoyela omkhulu. Ukuqina okuqinile kuqinisekisa ukuchitheka okusheshayo nokukhipha kakhulu kwekhabhoni.
• Ukuhlukaniswa kwe-Solid-Liquid: I-slurry eshisiwe iyahlolwa ngokuwasha okuphikisana nomjikelezo nokuhlunga kusetshenziswa uhlelo lwefiltha yuphuza oluqondile lwehhovisi lwehhovisi lwehhovisi olunezitebhisi ezine. Lokhu kuhlukanisa ngokusobala i-Pregnant Leach Solution (PLS) enenani elikhulu kakhulu kusuka kumashilwa. I-residue ithunyelwa ngokuphepha ngaphandle kwe-site, kuyilapho i-PLS enothombo lwekhabhoni iyageshwa epondini le-Pregnant Solution.

Isigaba III: Uhlelo Lokuhweba I-Solvent Extraction (SX)

Lesi sigaba sithuthukisa futhi sihlanza isixazululo sikashukela ocebile.

• Isigaba Sokukhipha IPLS izoshiswa iya kuma-mixer-settlers. Ku-mixers, i-PLS yamanzi iyaxutshwa kahle nge-organic extractant phakathi kweziteji ezimbili zokukhipha ngokumelene. I-phase ye-organic ikhetha ngokukhethekile ukuhlanganisa namagiya e-copper.
• Uphathiswa Rafinethi Ingxenye yamanzi engenalutho engenalutho (raffinate) icaciswa ukuze kususwe noma yimuphi umphumela we-organic ophoqelekile futhi iqhutshwa ehlathini lokugcina ukuze isetshenziswe kabusha njenge-solushoni sokugeza ohambweni lwe-leaching, kunciphisa ukusetshenziswa kwe-asidi namanzi.
• Ukuhlambulula nokukhipha uwoyela Iphase ye-organic ekhonjiswe ngekhabhoni iyadlula esigabeni esisodwa sokuhlanza ukuze kukhubazeke izimpukumo, emva kwalokho ihamba iya kutanki yokugcina. Bese ixhumana nesixazululo segesi esinamandla kakhulu ekuhlanzweni kwegesi. Lokhu kuphoqelela ikhabhoni ukuthi iphume kwi-fluid ye-organic futhi ingene kwi-phase yomanziphondwe, kuholela ku-Advance Electrolyte ehlanzekile, enokwandisa okuphezulu, ilungele esigabeni sokugcina.

Isigaba IV: Uhlelo lwe-Electrowinning (EW)

Ukuguqulwa kokugcina kusuka kwindawo yoketshezi kuya kwinsimbi eqinile kwenzeka endaweni yokugcina izinsimbi.

• Ukuhlelwa kweziceli I-electrolyte yesizindalwazi ishesha phakathi kwesihlungi samaphilisi wokulawula izinga lokushisa ngokunembile ngaphambi kokungena esitsheni sekhanda. Bese kuthi ngokudonsa komoya goqoka ukugeleza amajele ngamunye we-electrowinning polymer.
• Ukuvuma kwe-Electro-Chemical Ngaphakathi kwamangqamuzana, ama-anode angeke axazululeke (awenziwa ngensimbi ye-Pb-Ca-Sn) nama-cathode ephampu yokuqala ahlelekile. Ugesi oqondile uqhuba insimbi yensimbi kusukela esixazululweni iye kuma-cathode.
• Ukuqoqwa kwekhabhoni Ngemva kwesikhathi sokuzungeza okuthile, izikuluzi ezinkulu eziyinqaba zithola ama-cathode alayishwe futhi aziseke esithangamini sokuwasha. Ama_phutha ahlanzwe ahanjwa ngemishini ekhethekile yokususa nokuyisa ukuze akhiqize umkhiqizo wokugcina: ikhabhoni wensimbi ye-cathode 99.99% ihlanzekile, ilungele ukupakishwa nokuthunyelwa emakethe yomhlaba wonke.

Umgudu Omuhle Wokukhiqiza Ikhabhoni Ephakeme Ngokuhlanzeka

Inqubo ye-SX-EW echazwe ngenhla imele indlela esekwe kahle, ethembekile, futhi ekhanga kakhulu kwezokukhiqiza insimbi yomcaba ye-oxide. Ngokuhlanganisa ukugayiwa, ukugaya, ukukhipha, ukukhishwa kwe-solvent, nokugaya kwe-electrowinning kube uhlelo olulodwa oluhlelekile, lomhlangano wombalawenza ufinyelele imigomo eminingi ebalulekile:

• Ukutholakala okuphezulu komphumela we-metali Izikhathi zokubhidliza nokugubha zomjikelezo ovaliwe ziqinisekisa usayizi omuhle kakhulu wamangqamuzana okuthola, kuyilapho ukukhishwa okuphikisanayo ku-SX circuit kwehlisa kakhulu ukusebenza kahle kokudlulisa insimbi yekhwalithi.
• Ikhwalithi Yomkhiqizo: Ukuhlanganiswa kokukhetha ukwahlukana kwe-solvent nokuphuma kokukhishwa okuphakathi kokulawulwa kukhiqiza insimbi yekhathi ye-copper ehambisana nezimfuneko zokuhlanzeka eziphezulu (99.99% Cu), efanele izicelo ezidinga kakhulu.
• Ukusebenza kahle komsebenzi: Recycle streams—such as raffinate return to the leaching circuit and organic phase reuse—minimize reagent consumption and reduce liquid effluent discharge.
• Isibopho Semvelo Izinhlelo ukuqoqa uthuli, izitshalo zokuxazulula ezishintshwayo, kanye nezinqubo zokuphatha izingcezu ziqinisekisa ukuthi ukusebenza kuhambisana nezindinganiso zanamuhla zemvelo.

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.

Njengoba umfuno wekhabhoni uqhubeka nokukhula futhi imboni icabanga ngokuya emithonjeni ye-oxide ukuze enze ukusiza ukukhiqizwa kwe-sulfide, inqubo ye-SX-EW isalona uhlobo lobuchwepheshe obuphambili bokubuyisela ikhabhoni ngokuphumelelayo, ngokonga izindleko, futhi obuqinisekisa imvelo.

Sezizenjani ukukwenza ngcono ukuhamba komsebenzi wakho wokucubungula i-copper? Ungashi lakho lemiphumela yokubuyiselwa kulo. Xhumana nethimba lethu lobunjiniyela bezemayini namuhla ukuze uthole umklamo wangokwezifiso wokugeleza, usayizi lwezisetshenziswa, kanye nokuhlaziywa okuphelele kwe-Total Cost of Ownership (TCO).
