Ukusetshenziswa kwe-Sodium Cyanide Replacement Technologies Emayini Amancane

Isingeniso

Embonini yezimayini, ikakhulukazi for Izimayini Ezincane, ukukhishwa kwezinsimbi eziyigugu njengegolide nesiliva sekuyisikhathi eside kuncika kukho I-Sodium Cyanide. Nokho, ukusetshenziswa i-sodium cyanide iza nokukhathazeka okubalulekile kwezemvelo nokuphepha. Inobuthi obuphezulu futhi ingabangela ukungcoliswa okukhulu emithonjeni yamanzi futhi ilimaze izilwane zasemanzini. Ngokugxila okwandayo ekuvikelweni kwemvelo kanye nemithetho eqinile emhlabeni wonke, izimayini ezincane zingaphansi kwengcindezi enkulu yokuthola ezinye izindlela zokukhipha insimbi. Lesi sihloko sihlola ukusetshenziswa kwe I-sodium cyanideI-Replacement Technologys ezimayini ezincane, okuhloswe ngazo ukunikeza ukuqonda okuphelele kwalezi zixazululo ezisimeme.

Ukungalungi kweSodium Cyanide Emayini Amancane

Izingozi Zemvelo

Izimayini ezincane zivame ukungabi nezinhlelo ezithuthukisiwe zokulawula udoti. Lapho sodium i-cyanide isetshenziswa, kunengozi enkulu yokuvuza kwe-cyanide emanzini aseduze phakathi nenqubo yokukhipha. Ngisho nenani elincane le-cyanide lingaba yingozi kakhulu ku-ecosystem. Ngokwesibonelo, kungaholela ekufeni kwezinhlanzi nezinye izinto eziphilayo zasemanzini, kuphazamise lonke uchungechunge lokudla kwasemanzini. Ngaphezu kwalokho, i-cyanide ingaqhubeka isikhathi eside endaweni ezungezile, ibangele ukulimala kwesikhathi eside enhlabathini naseqophelweni lamanzi.

Izingozi Zokuphepha

Ukuphatha i-sodium cyanide kudinga izinyathelo zokuphepha eziqinile. Izimayini ezincane zingahle zingabi nazo zonke izinsiza zokutshala ezinsizeni ezifanele zokuphepha nokuqeqeshwa kwabasebenzi bazo. Ukuchayeka ngengozi ku-sodium cyanide kungabangela izinkinga zempilo ezimbi kubavukuzi, okuhlanganisa ukwehluleka ukuphefumula ngisho nokufa. Ngaphezu kwalokho, uma kwenzeka izinhlekelele zemvelo noma izingozi, ukugcinwa nokuthuthwa kwe-sodium cyanide ezimayini ezincane kungaba yingozi enkulu emiphakathini ezungezile.

Obunye Ubuchwepheshe ku-Sodium Cyanide

I-Thiosulfate Leaching

I-Thiosulfate leaching iyindlela engeyona enobuthi esikhundleni sokukhishwa okusekelwe ku-cyanide. Isebenzisa ion thiosulfate ukuncibilikisa igolide ores. Le ndlela ihambisana kakhulu nemvelo njengoba ingakhiphi izinto ezinobuthi obukhulu. Ezimayini ezincane, i-thiosulfate leaching ingaba inketho efanelekile njengoba ingasetshenziswa ezinhlotsheni ezihlukahlukene ze-ore. Nokho, inazo izinselele ezithile. Kungase kudinge ukuthuthukiswa kwenqubo eyengeziwe, njengokulawula i-pH kanye nezinga lokushisa lesisombululo se-leaching ngokunembe kakhudlwana. Futhi, izindleko zokusebenza ziphakeme uma kuqhathaniswa ne-cyanide leaching, ikakhulukazi ngenxa yezindleko zama-reagents e-thiosulfate kanye nesidingo semishini eyinkimbinkimbi kwezinye izimo.

I-Chloride Leaching

I-chloride leaching ihilela ukusebenzisa ama-ion e-chloride ukuncibilikisa igolide nezinye izinsimbi ezivela ku-ores. Iveza ubungozi obuphansi bemvelo uma kuqhathaniswa ne-cyanide. Izimayini ezincane zingazuza kule ndlela njengoba ingavumelana nezimo zendawo. Isibonelo, ezindaweni lapho i-chloride - izinto eziqukethe zifinyeleleka kalula, izindleko zama-reagents zingancishiswa. Kodwa-ke, ukuphatha imikhiqizo kagesi kanye nemfucuza evela ku-chloride leaching kungaba nzima. I-Chloride - udoti ocebile ungadinga ukwelashwa okukhethekile ukuvimbela ukugqwala kwemishini kanye nokungcoliswa kwemvelo.

I-Bioleaching

I-Bioleaching isebenzisa umsebenzi we-microbial ukukhipha izinsimbi ku-ores. Lena enye indlela esimeme futhi eco-friendly. Ama-microorganisms, njengama-bacteria athile, angakwazi ukudiliza insimbi futhi akhulule izinsimbi. Ezimayini ezincane, i-bioleaching inenzuzo yokuthi kulula ukuyimisa kwezinye izimo. Ayidingi imishini eyinkimbinkimbi kakhulu. Kodwa-ke, ukusebenza kahle kwe-bioleaching kungakhawulwa yizinto ezifana nohlobo lwe-ore kanye nomsebenzi wama-microorganisms. Amanye ama-ore angase angaboli kalula ama-microorganisms atholakalayo, futhi ukukhula nokusebenza kwama-microorganisms kungase kuthinteke izimo zemvelo ezifana nezinga lokushisa ne-pH.

Ukusetshenziswa Kwemvelo - Ama-ejenti Okugqoka Egolide anobungane

Kunezinhlobo eziningana ze-gold dressing agents ezinobungane nemvelo ezitholakala emakethe ezingathatha indawo ye-sodium cyanide. Isibonelo, i-"Jinchán" friendly Environmental dressing agent ye-gold dressing agent eyenziwe yi-Guangxi Senhe High - tech Co., Ltd. inezinzuzo zobuthi obuphansi, izinga eliphezulu lokululama, kanye nokusebenza okulula. Lezi zinhlobo ze-agents zingasetshenziswa ezinqubweni ezifanayo ne-sodium cyanide, njenge-heap leaching, i-pool leaching, kanye I-Carbon - izinqubo ze-pulp. Bangakwazi ukukhipha igolide ngempumelelo ezinhlotsheni ezahlukene zama-ore, kufaka phakathi lawo anezinhlanganisela eziyinkimbinkimbi. Esinye isibonelo yi-CNFREE sodium cyanide substitute, engasetshenziswa ngqo ekugcotshweni nasekuhluzweni kwe-ore yegolide ngaphandle kokushintsha imishini yokuqala kanye nenqubo ye-cyaning, okufeza ngempela umgomo wokuvikelwa kwemvelo okuluhlaza.

Izinselelo Nezixazululo Ekusebenziseni Obunye Ubuchwepheshe Ezimayini Ezincane

Izindleko - ukusebenza kahle

Enye yezinselelo eziyinhloko zezimayini ezincane ekwamukeleni obunye ubuchwepheshe yizindleko - ukusebenza kahle. Izindlela eziningi ezihlukile, ezifana ne-thiosulfate leaching, zingase zibe nezindleko zokutshala eziphakeme zokuqala zemishini nama-reagents. Ukuze kubhekwane nalokhu, izimayini ezincane zingacabangela ukusebenzisana nezikhungo zocwaningo noma izinkampani ezinkulu zezimayini ukuze zabelane ngezindleko zocwaningo nokuthuthukiswa kwezinqubo ezingabizi kakhulu. Ukwengeza, uxhaso lukahulumeni noma izinxephezelo zinganikezwa ukukhuthaza izimayini ezincane ukuthi zamukele lobu buchwepheshe obuqhubekayo.

Isazi Sezobuchwepheshe

Izimayini ezincane zingase zintule ubuchwepheshe obudingekayo ukuze zisebenze futhi zithuthukise lobu buchwepheshe obuhlukile. Izinhlelo zokuqeqesha zingahlelwa yizinhlangano zezimboni noma ama-ejensi kahulumeni ukuze kufundiswe abavukuzi ngokusetshenziswa okufanele kwezindlela ezintsha zokumba. Isibonelo, ukuqeqeshwa kokuthi ungalawula kanjani amapharamitha ku-thiosulfate leaching noma indlela yokuphatha indawo ye-microbial ku-bioleaching. Ngaphezu kwalokho, abahlinzeki bezobuchwepheshe banganikeza - ukwesekwa kwezobuchwepheshe esizeni ezimayini ezincane phakathi nezigaba zokuqala zokwamukela ubuchwepheshe obusha.

Ukuguqulwa Kwezimiso

Imvelo yokulawula yezimayini ishintsha njalo. Izimayini ezincane kudingeka ziqinisekise ukuthi obunye ubuchwepheshe ezibusebenzisayo buhambisana nemithetho yasekhaya neyamazwe ngamazwe. Lokhu kudinga ukuxhumana okuseduze neziphathimandla ezilawulayo. Izigungu ezilawulayo zingabamba iqhaza futhi ngokunikeza imihlahlandlela ecacile emazingeni amukelekayo omthelela wendawo kanye namazinga okuphepha kwezinye izindlela zobuchwepheshe, okwenza kube lula ngezimayini ezincane ukuzivumelanisa nezimo.

Isiphetho

Ukusetshenziswa kobuchwepheshe bokubuyisela i-sodium cyanide ezimayini ezincane kubalulekile ekuthuthukisweni okusimeme embonini yezimayini. Nakuba kunezinselele ezifana nezindleko - ukusebenza kahle, uchwepheshe bezobuchwepheshe, nokuzivumelanisa nezimo zokulawula, izinzuzo zalobu buchwepheshe obuhlukile ngokuphathelene nokuvikelwa kwemvelo nokuphepha zibalulekile. Ngokubhekana nalezi zinselele ngokusebenzisana, ukuqeqeshwa, kanye nokuxhumana okungcono neziphathimandla ezilawulayo, izimayini ezincane zingadlulela ngempumelelo ekusebenziseni izindlela zokumba ezisimeme, ziqinisekise ukusebenza kwesikhathi eside kokusebenza kwazo kuyilapho zinciphisa umthelela wazo endaweni ezungezile nasemphakathini.
