Inqubo Ye-Carbon Slurry Yokudonswa Kwegolide: Ukuzuza Izinga Eliphezulu Lokutholwa Kwegolide elingu-94%.

Emkhakheni wokumbiwa nokumbiwa kwegolide, ukusebenza kahle kanye namazinga aphezulu okuthola kabusha kubaluleke kakhulu. I Inqubo ye-Carbon Slurry iye yavela njengendlela ehamba phambili, edume ngekhono layo lokuzuza inani elimangalisayo Igolide Lokubuyisela Izinga kufika ku-94%. Lesi sihloko sigxila ezinkingeni ze- I-Carbon inqubo yodaka, ukuhlola izinzuzo zayo, izindlela zokusebenza, kanye nokubaluleka kwayo embonini yezimayini zegolide zanamuhla.

Ukuqonda Inqubo Ye-Carbon Slurry

Inqubo ye-carbon slurry iyindlela esetshenziswa kakhulu yokukhipha igolide ku-ore. Kubandakanya uchungechunge lwezinyathelo ezihlelwe kahle ezivumela ukuhlukaniswa kahle kwegolide kumaminerali azungezile.

Ukulungiselela Ore

Inqubo iqala ngokukhishwa kwegolide - insimbi enensimbi emayini. Itshe lensimbi libe selithuthwa liyiswe lapho ligaywa khona, lapho ligaywa khona futhi ligaywe. Lesi sinyathelo sibalulekile njengoba sehlisa insimbi ukuze ilingane kahle, ikhulise indawo engaphezulu etholakalayo ukuze kusetshenziswe amakhemikhali alandelayo. I-ore egayiwe kanye nephansi ibe isihlanganiswa namanzi ukuze kwakheke udaka, olulungele isigaba esilandelayo senqubo.

I-Cyanidation

I-Cyanidation iyisinyathelo esibalulekile enqubweni ye-carbon slurry. Kulesi sigaba, isisombululo se i-cyanide yengezwe ku-slurry. I-cyanide ihlangana negolide ku-ore, iguqule ibe yigolide elincibilikayo - i-cyanide complexes. Lokhu kusabela kwenzeka emathangini amakhulu anyakazayo, okuqinisekisa ukuthi isixazululo se-cyanide sixubana kahle ne-ore slurry, okwandisa ukukhishwa kwegolide.

I-Carbon Adsorption ecushiwe

Uma igolide selishintshiwe laba izinto ezincibilikayo, ikhabhoni ecushiwe yengezwa odaka. Ikhabhoni ecushiwe inesakhiwo esinezimbobo kakhulu, esihlinzeka ngendawo enkulu yokukhangisa. Izakhiwo zegolide - i-cyanide zikhangwa ngaphezulu kwekhabhoni ecushiwe, lapho zikhangiswa khona. Le nqubo ikhetha kakhulu, lapho ikhabhoni ecushiwe ikhetha ngokukhethekile izingxube zegolide - i-cyanide ngaphezu kwezinye izinto eziku-slurry. Ukufakwa kwegolide kukhabhoni ecushiwe kuyinqubo yekhemikhali ephathekayo, lapho ama-ion egolide - i-cyanide ebanjwa endaweni yekhabhoni ngokusebenzisa amandla ahlukahlukene kanye nokusebenzisana kwamakhemikhali namaqembu asebenzayo kukhabhoni.

Ukuhlukaniswa Kwekhabhoni Elayishiwe

Ngemuva kwenqubo ye-adsorption, ikhabhoni ecushiwe, manje elayishwe igolide, idinga ukuhlukaniswa ne-slurry esele. Lokhu ngokuvamile kufinyelelwa kusetshenziswa izikrini noma ezinye izindlela zokuhlukanisa. Ikhabhoni elayishiwe ehlukanisiwe ibe isilungele isinyathelo esilandelayo senqubo, esibandakanya ukutholwa kwegolide kukhabhoni.

Ukutholwa Kwegolide Kusuka Kukhabhoni Elayishiwe

Kunezindlela eziningana zokuthola igolide kukhabhoni elayishiwe. Enye indlela evamile i-desorption, lapho igolide - i-cyanide complexes ikhishwa kukhabhoni kusetshenziswa isixazululo esishisayo, esigxilile. I-Sodium Cyanide kanye ne-sodium hydroxide. Ikhambi legolide elincibilikisiwe - i-cyanide libe selifakwa ngaphansi kwe-electrolysis noma ezinye izindlela zokwehlisa igolide ngesimo salo sensimbi. Enye indlela ukuncibilika ngokuqondile kwekhabhoni elayishiwe, lapho ikhabhoni ishiswa khona esithandweni, bese igolide litholwa emlotheni owumphumela.

Izinzuzo Zenqubo Ye-Carbon Slurry

Izinga eliphezulu Lokubuyisela Igolide

Inqubo ye-carbon slurry isebenza kahle kakhulu ekubuyiseni igolide ensimbini ensimbi, ngenani eliphelele lokutholwa kwegolide elifinyelela ku-94%. Leli zinga eliphezulu lokutakula lidalwe ukuhlanganiswa kwe I-Cyanidation inqubo, encibilikisa ngempumelelo igolide, kanye ne-adsorption ekhethiwe yegolide - i-cyanide complexes ngekhabhoni ecushiwe. Ikhono lokubuyisa ingxenye enkulu yegolide elikhona ensimbini liyinzuzo ephawulekayo, njengoba likhulisa inani lezomnotho lomsebenzi wokumba.

Ukufaneleka Kwezinhlobo Ezihlukene Zensimbi

Inqubo ye-carbon slurry inemisebenzi eminingi futhi ingasetshenziswa ezinhlobonhlobo zegolide - ore, kuhlanganise ne-low-grade ores, ores oxidized, nama-ores ane-mineralogy eyinkimbinkimbi. Lokhu kuvumelana nezimo kukwenza kube ukukhetha okuthandwayo emisebenzini eminingi yezimayini zegolide emhlabeni jikelele, njengoba kuvumela ukukhishwa kwegolide ezinsimbini ezingase zibe nzima noma ezingenamnotho ukucutshungulwa kusetshenziswa ezinye izindlela.

Inqubo Eyenziwe Lula

Uma kuqhathaniswa nabanye bendabuko Ukukhishwa Kwegolide izindlela, inqubo carbon slurry has inqubo kuqhathaniswa lula. Iqeda isidingo sokuqina okuqinile nokubizayo - amasu okuhlukanisa uketshezi avame ukudingeka kwezinye izinqubo. Ukusetshenziswa kwekhabhoni ecushiwe ye-adsorption ngqo kusuka ku-slurry kunciphisa inani lezinyathelo zokucubungula, okuholela emalini ephansi kanye nezindleko zokusebenza.

Izinzuzo Zemvelo

Mayelana nomthelela wemvelo, inqubo ye-carbon slurry inezinzuzo eziningana. Ukusetshenziswa kwe-cyanide endaweni elawulwayo nequkethwe, kanye nezindlela ezifanele zokuphatha imfucuza, kusiza ukunciphisa ukukhululwa kwezinto eziyingozi endaweni ezungezile. Ukwengeza, izinga eliphezulu lokutholwa kwegolide lisho ukuthi insimbi encane idinga ukucutshungulwa ukuze kutholwe inani elifanayo legolide, kuncishiswe ingqikithi yemvelo yomsebenzi wokumba.

Izindleko - Ukusebenza kahle

Inhlanganisela yamazinga aphezulu okubuyisela, inqubo eyenziwe lula, kanye nomthelela oncishisiwe wemvelo kwenza inqubo ye-carbon slurry ibe nezindleko - ngempumelelo. Nakuba kunezindleko zokuqala zekhephithali ezihambisana nokusetha indawo yokucubungula, izindleko zokusebenza zesikhathi eside ziphansi. Ikhono lokukhipha igolide ngendlela ephumelelayo ezinhlobonhlobo zezinsimbi liphinde likhulise inzuzo yokusebenza kwezimayini, njengoba livumela ukuxhashazwa kwezinsiza okungenzeka bezibhekwa njengencane ngaphambili.

Izicelo Embonini Yezimayini Zegolide

Inqubo ye-carbon slurry isetshenziswa kakhulu emisebenzini yokumba igolide ngezinga elikhulu emhlabeni jikelele. Izimayini ezisezifundeni ezinjenge-Afrika, i-Australia, neNyakatho Melika zivame ukusebenzisa le nqubo ukuze zikhiphe igolide endaweni yazo yensimbi. Isibonelo, kwezinye izimayini zase-Afrika, inqubo ye-carbon slurry isetshenziswe ngempumelelo ukuze kucutshungulwe amatshe egolide asezingeni eliphansi, ane-oxidized kakhulu, okwenza ukuba ukumbiwa kwegolide okwakungenawo umnotho kubuyiselwe. E-Australia, inqubo isetshenziswa ezimayini ezinemizimba ye-ore eyinkimbinkimbi, lapho ukuguquguquka kwayo kanye namazinga aphezulu okuthola kabusha kuye kwafakazela ukuthi kubaluleke kakhulu.

Isiphetho

Inqubo ye-carbon slurry yokukhipha igolide inikeza inqwaba yezinzuzo, namandla ayo okuthola inani eliphelele lokutholwa kwegolide elifika ku-94% libe isici esivelele. Ngokusebenzisa inhlanganisela ye-cyanidation, i-carbon adsorption ecushiwe, nezindlela eziphumelelayo zokuhlukanisa, le nqubo iguqule imboni yezimayini zegolide. Ukuguquguquka kwayo, ubulula, izinzuzo zemvelo, kanye nezindleko - ukusebenza kahle kuyenza ibe inketho ekhethwayo kubavukuzi begolide emhlabeni wonke. Njengoba isidingo segolide siqhubeka sikhula, inqubo ye-carbon slurry ngokungangabazeki izodlala indima ebalulekile ekuqinisekiseni ukukhishwa okusimeme nokusebenza kahle kwale nsimbi eyigugu.
