Ingabe amaVats eConkriyiti angathuthukisa izinqubo zokukhishwa kwegolide?
Isikhathi:23 October 2025
Ukukhishwa kwegolide kuyinqubo ebalulekile embonini yokumbiwa, ikakhulukazi esetshenziselwa ukukhipha igolide emadlaleni. Ukusebenza kahle kwale nqubo kuthinta kakhulu inhlangano yokwenza inzuzo nokugcina izinqubo zokumbiwa. Ngokwesiko, ukukhishwa bekwenziwa ezinkambini zensimbi ezinkulu, kodwa ukuthuthuka kwamuva kubonisa ukuthi amavatha e-concrete angahlinzeka ngesisombululo esingcono. Le ndatshana ihlola amathuba wamavatha e-concrete ukuze athuthukise izinqubo zokukhishwa kwegolide.
Ukuqonda Ukukhipha Igolide
Ukukhishwa kwegolide kuhilela ukuguqulwa kwegolide ukusuka kumthelela wayo kusetshenziswa izixazululo zamakhemikhali. Indlela evamile kakhulu iwukucwaningwa kwecyanide, lapho isixazululo secyanide sisetshenziselwa ukuguqula igolide. Le nqubo ivamise ukuhlanganisa izinyathelo ezithile:
- Ukuphuka nokugaya: I-ore iyaphukiswa futhi igaywe ukuze kutholakale amaphuzu egolide.
- Ukuphuma: I-ore elisemhlabeni ixutshwa nesixazululo se-cyanide emathankini amakhulu.
- Ukuphendula: Ama-complex we-gold-cyanide adlula ku-carbon evulekile.
- Ukubuyiselwa: Igolide ikhishwa kwi-carbon, futhi isisombululo siyabuyiselwa.
Ithangi le-Leaching las传统
Ngokwesiko, ukukhishwa kwegolide kwenziwa ezitsheni zensimbi ezinkulu. Lezi zitsheni zakhelwe ukumelana nobungozi bokubola bezixazululo ze-cyanide kanye nomphumela ophukisayo wesiphethu somkhiqizo. Nokho, izitsheni zensimbi zinezinselelo eziningi:
- Izindleko Zokuqala Eziphakeme: Ukwakhiwa nokufakwa kwezitsha zensimbi kudla imali eningi.
- Ukugcinwa: Amathangi ensimbi adinga ukugcinwa njalo ukuze avimbele ukuhuzuka.
- Izinkinga Zemvelo: Ukukhiqiza insimbi kunezimpawu ezinkulu zemvelo.
Izinzuzo zeBhakede Lesigcino
Izitsha zendlela yensimbi zikhombisa indlela ephumelelayo yokukhetha izitsha zokusebenza. Nazi ezinye izinzuzo ezingenzeka:
Izindleko-Efekthive
- Izindleko Zokwakha Eziphansi: Ikonkrithi ngokuvamile ibiza kancane kunezinsimbi, yehlisa imali yokuqala yokutshala.
- Ukuphila: Ivathe zethusi azinakuphupha kalula, zizokwehlisa izindleko zok maintenance ngokuhamba kwesikhathi.
Izinto Ezinhle Zemvelo
- Ukuqina: Ukukhiqizwa kweconcrete kunezinyathelo eziphansi zokukhishwa kwekhabhoni uma kuqhathaniswa nensimbi.
- Ukusebenza kabusha: Amathangi enkanyezi angase asetshenziswe kabusha noma abuyele emuva ekupheleni kwesikhathi sawo sokuphila.
Ukusebenza kahle kwezokusebenza
- Ukuvikelwa Kwezehlakalo: I-Concreate inikeza ukuvikelwa kwezehlakalo okungcono, okungathuthukisa ukusebenza kahle kwenqubo yokukhipha.
- Ukuvumelana: Amavathi e-concrete angakhuphukiswa kalula ukuze ahambisane nezidingo ezithile zokusebenza nemininingwane yesiza.
Izinkinga Nezinto Okufanele Zicatshangelwe
Nakuba ama-vat e-concrete enza izinzuzo eziningi, kukhona nezinselelo nezinto okufanele zicatshangelwe:
Ukumelana Nezinto Zamakhemikhali
- I-Cyanide Compatibility: I-concrete kumele iphathwe noma ifakwe ukuvikela izinto eziyingozi zokuhlaselwa kwezixazululo ze-cyanide.
- Ubumsulwa Bamamaterial: Ukuqinisekisa ubumsulwa besikhathi eside bokhonkolo endaweni enokhemikhali eyinqaba kubalulekile.
Ukuklama Kwesakhiwo
- Umthamo Wokuthwala: Izitsha zekhonkolo kumele zenzelwe ukumelana nesisindo kanye nomfutho we-ore slurry.
- Ukwenza: Ukufaka kahle kubalulekile ukuvikela uku leak kanye nokuqinisekisa ukuphepha kwemvelo.
Izifundo Zobuciko Nezinhlelo
Ukwakha okuningi sekudale ukukhangwa kwezinsiza ezisebenzayo zokukhishwa kwegolide. Izibonelo ezibalulekile zifaka:
- Iphrojekthi A: Imithetho yokumba enkulu elinganiselwe eNingizimu Melika yaphumelele ukufaka amashubhu e-concrete, kuholele ekwenyukeni kwexabiso lokusebenza ngo-15%.
- Project B: Ukuhlinzekwa okukhulu e-Afrika kubike ukuqhubeka kwezindleko zokukhipha okuthile kanye nokuncipha kwesikhathi sokulungisa ngemva kokushintshela ezitsha ze-concrete.
Isiphetho
Iziphuzo zomxube zinekhulu lokuthuthukisa izinqubo zokukhishwa kwegolide ngokunikeza ukonga kwemali, izinzuzo zemvelo, kanye nokusebenza kahle. Nokho, ukubheka kahle ukumelana nezinhlaka zamakhemikhali nokwakheka kwesakhiwo kubalulekile. Njengoba imboni yokumbiwa kwemigodi iqhubeka ifuna izixazululo eziqhubekayo nezisebenzayo, iziphuzo zomxube zingase zibe ukukhetha okuthandwayo kakhulu ezindleleni zokukhishwa kwegolide.
Ngokusebenzisa izinzuzo zezimboni zensimbi, izinkampani zokumba zingathuthukisa izinqubo zazo, zehlise izindleko, futhi zinciphise umthelela kwemvelo, ekugcineni zibe nomthelela omuhle ezindleleni zokumba ezinzile.
