Uyihlengahlengisa njani idosi yesodium cyanide ngokweOre Particle Ubungakanani?

Kwintsimi yokulungiswa kwezimbiwa, ngakumbi kwi inkqubo ye-cyanidation ukukhutshwa kwegolide nesilivere, ukulungelelanisa Isodium cyanide Idosi ngokobungakanani besuntswana lentsimbi ibalulekile ekwenzeni ngcono ukusebenza kakuhle kwe-leaching kunye nokunciphisa iindleko zemveliso. Eli nqaku lijolise ekunikezeni isikhokelo esibanzi malunga nendlela yokwenza uhlengahlengiso olunjalo.

Indlela yeMpembelelo yoBubungakanani beNcam yentsimbi kwiSabelo seCyanidation

Ummandla oMphezulu kunye ne-Reaction Kinetics

Amasuntswana ore acolekileyo anommandla othile omkhulu ngakumbi. Nini sodium cyanide isisombululo sisabela ngentsimbi ekrwada, indawo enkulu yomphezulu ivumela iindawo zoqhagamshelwano ngakumbi phakathi kwe i-cyanide iion kunye neeminerali ekujoliswe kuzo (ezifana negolide okanye isilivere). Ngokutsho kwethiyori ye-reaction kinetics, ireyithi yokusabela ihambelana nommandla we-reactants. Umzekelo, kuphononongo malunga ne-cyanidation yegolide, kwafunyaniswa ukuba xa ubungakanani bamasuntswana e-ore buncitshisiwe ukusuka kubukhulu oburhabaxa ukuya ku -38 μm kunye nomlinganiselo womxholo wama-75%, umlinganiselo wokuvuza kwegolide unyuke kakhulu. Ngamasuntswana acwebileyo, iiathom zegolide ngaphezulu kumphezulu zivezwe kwi-ion ye-cyanide, iququzelela ukusabela okusebenzayo.

Amasuntswana arhabaxa, kwelinye icala, anommandla omncinci okhoyo wokusabela. Iiyoni ze-cyanide zinokusabela kuphela kunye nomaleko wangaphandle wamasuntswana, kwaye ukusasazwa kweeyoni ze-cyanide ngaphakathi kwamasuntswana arhabaxa kucotha. Oku kukhokelela kwireyithi yokusabela esezantsi kunye nokuvuza okungaphelelanga kweeminerali ekujoliswe kuzo ngaphakathi kwamasuntswana.

Umqobo wokusasaza

Kwimeko yentsimbi ekrwada ecolekileyo, umgama ekufuneka iiyoni zecyanide zisasazeke ukuze zifike kwiiminerali ekujoliswe kuzo mfutshane. Oku kunciphisa ukuxhathisa ukusasazwa kwaye kwenza ukusabela ngokukhawuleza. Njengoko ubungakanani bamasuntswana e-ore bukhula, indlela yokusasazwa kweeyoni ze-cyanide ngokusebenzisa i-porous structure yamasuntswana e-ore iba nde. Ubukho beminerali ye-ganggue kumasuntswana bunokusebenza njengomqobo wokusasaza. Umzekelo, ukuba kukho iileyibhile zeminerali ye-non-reactive gangue ejikeleze igolide-ethwele iiminerali kwisuntswana elirhabaxa, kuya kuthatha ixesha elide ukuba ii-ion ze-cyanide zingene kwaye zisabele kwigolide, nto leyo ekhokelela ekusebenzeni okusezantsi kokuvuza.

Umlinganiselo wobungakanani beNceba yentsimbi

Uhlalutyo lweSieving

I-Sieving yindlela eqhelekileyo kunye necacileyo yokumisela ubungakanani bamasuntswana e-ore. Iseti yeesefu eziqhelekileyo ezinobukhulu obahlukeneyo bomnatha ziyasetyenziswa. Isampulu yentsimbi ekrwada ibekwe kwisefu engaphezulu yesitaki, emva koko isitaki sishukunyiswa ngoomatshini kangangexesha elithile. Amasuntswana adlula kwisefu nganye ayaqokelelwa aze alinganiswe. Ngokubala ipesenti yobuninzi beengqungquthela ezigcinwe kwi-sieve nganye, ukusabalalisa ubungakanani be-particle ye-ore samples kunokufumaneka. Umzekelo, kwishishini lokulungisa intsimbi ekrwada, ukuba intsimbi ihluzwa ngoluhlu lwezihluzo ezinobukhulu obungama-200. 325. kunye no-400. ipesenti yamasuntswana amancinane kunobungakanani bomnatha ngamnye inokumiselwa, nto leyo inceda ekuqondeni ukucoleka kwentsimbi ekrwada.

Laser Diffraction Particle Ubungakanani Uhlalutyo

Le yindlela ephucukileyo nechanekileyo. Abahlalutyi be-laser diffraction basebenza ngokusekelwe kumgaqo wokuba xa i-laser beam idlula kwinkqubo ye-particle edibeneyo, iinqununu ziya kuchitha ukukhanya kwe-laser. I-angle kunye nokuqina kokukhanya okuhlakazekileyo kuhambelana nobukhulu beqhekeza. Ngokulinganisa ukukhanya okuhlakaziweyo, isixhobo sinokubala ukusabalalisa ubungakanani be-particle ye-ore sample. Inokubonelela ngeenkcukacha ezithe kratya malunga noluhlu lobungakanani bamasuntswana, kubandakanywa amasuntswana amahle kakhulu anokuba nzima ukulinganisa ngokuchanekileyo ngokusefa. Le ndlela iluncedo ngakumbi xa ujongana neentsimbi ezikrwada ezinoluhlu olubanzi lweesayizi zamasuntswana okanye xa imilinganiselo echanekileyo ephezulu ifunekayo ukulungiselela inkqubo ye-cyanidation.

Imigaqo kunye neendlela zoLungiso lweSodium Cyanide Dosage

Imigaqo ngokubanzi

Ubudlelwane obulinganayo phakathi koluhlu oluthile

Ngokubanzi, phakathi koluhlu oluthile, inani le Isodium cyanide eyongeziweyo ilingana nommandla womphezulu wamasuntswana ore. Njengoko i-ore isayizi ye-ore iya icoleka (ummandla omkhulu womphezulu), i-sodium cyanide eninzi iyafuneka ukuqinisekisa ukusabela okupheleleyo kunye neeminerali ekujoliswe kuzo. Nangona kunjalo, olu lwalamano alukho mgca ngokungenasiphelo. Xa isixa se-sodium cyanide sidlula kwinqanaba elithile, ukusebenza kakuhle kwe-leaching akunakunyuka kakhulu, kwaye kuya kubangela inkunkuma yeekhemikhali kunye nokwandisa iindleko zokuvelisa.

Ukuqwalaselwa kweempawu zeOre

Iindidi ezahlukeneyo ze-ores zinemichiza eyahlukeneyo kunye nezakhiwo. Ezinye ii-ores zinokuba neeminerali ezidla ii-ion ze-cyanide, ezifana neeminerali ezithile ze-sulfide. Kwiimeko ezinjalo, nangona ubungakanani besuntswana elifanayo, i-sodium cyanide eninzi inokufuneka ukufezekisa umphumo oyifunayo. Ngokomzekelo, ukuba i-ore iqulethe i-pyrite ephezulu, i-pyrite inokusabela kunye ne-cyanide ions kunye ne-oksijini kwisisombululo, idla i-cyanide. Ngoko ke, idosi ye-cyanide kufuneka ihlengahlengiswe ngokuhambelana nokwakheka kweminerali ethile ye-ore.

Iindlela Zokulungisa

Uvavanyo Lelebhu

Ngaphambi kokuveliswa kwamashishini amakhulu, iimvavanyo zaselabhoratri kufuneka zenziwe. Lungisa iisampulu ezikrwada ezinobungakanani bamasuntswana ahlukeneyo ngokusila nokusefa. Emva koko, yenza uvavanyo lwe-cyanidation leaching kwezi sampuli ngeedosi ezahlukeneyo zesodium cyanide. Ukulinganisa izinga lokuvuza kwezimbiwa ekujoliswe kuzo (umzekelo, igolide okanye isilivere) phantsi kweemeko ezahlukeneyo. Ngokuhlalutya idatha yovavanyo, misela ubudlelwane phakathi kobungakanani be-ore, umthamo we-sodium cyanide, kunye nesantya sokuvuza. Ngokomzekelo, kwi-ore yegolide enobungakanani be-particle -200 mesh (malunga ne-74 μm), uvavanyo lwebhubhoratri lunokubonisa ukuba xa idosi ye-sodium cyanide inyuswa ukusuka kwi-1 kg / t ukuya kwi-2 kg / t, izinga legolide le-leaching linyuka ukusuka kwi-70% ukuya kwi-85%, kodwa ukwandisa umthamo ukuya kwi-3 kg / t ukuya ku-87% kuphela. Le datha ingasetyenziswa njengesalathiso kwimveliso yeshishini.

Ukubeka iliso kwi-Intanethi kunye noLungiso kwiMveliso yoShishino

Kwimveliso yoshishino, abahlalutyi besayizi ye-intanethi ye-intanethi banokufakelwa ukujonga ngokuqhubekayo ubungakanani be-particle ye-ore engena kwinkqubo ye-cyanidation. Ngokusekwe kubudlelwane obusekiweyo phakathi kobungakanani besuntswana kunye nedosi yesodium cyanide evela kuvavanyo lwaselabhoratri, inkqubo yokudosa ngokuzenzekelayo inokulungiswa ngexesha lokwenyani. Ngokomzekelo, ukuba i-analyzer yesayizi ye-particle ye-intanethi ibona ukuba i-avareji yesayizi ye-ore ilungile, inkqubo yokudosa ngokuzenzekelayo inokunyusa idosi ye-sodium cyanide ngokufanelekileyo ukugcina ukusebenza kakuhle kwe-leaching.

Ekugqibeleni, ukulungelelanisa umthamo we-sodium cyanide ngokwe-ore particle ubungakanani ngumsebenzi onzima kodwa obalulekileyo kwinkqubo ye-cyanidation. Ngokuqonda indlela yempembelelo yobungakanani bamasuntswana e-ore, ukulinganisa ngokuchanekileyo ubungakanani bamasuntswana, kunye nokulandela imigaqo yohlengahlengiso olufanelekileyo kunye neendlela, ishishini lokulungisa izimbiwa linokuphucula ukusebenza kakuhle kwe-cyanidation leaching, ukunciphisa ukusetyenziswa kweekhemikhali, kunye nokuphucula izibonelelo zoqoqosho kunye nokusingqongileyo ngokubanzi.
