Embonini yegolide ye-cyanidation, ukuthuthukisa ukusebenza kahle kwe-leaching kuwumgomo obalulekile wokukhulisa ukusetshenziswa kwezinsiza kanye nembuyiselo yezomnotho. Ukuze kubhekwane nalokhu, kwenziwa uchungechunge lwezifundo zokuhlola ezibanzi mayelana nokusetshenziswa kwe-leaching enomoya-mpilo onomfutho womoya osemkhathini esitshalweni se-cyanidation, kugxilwe ekugxilweni kwegolide kwesitshalo.
Ukusetha Kokulinga
Izikali ezintathu ezihlukene zokuhlola-isilinganiso sebhentshi, i-semi-industrial, nezimboni-zenziwe. Ukuhlolwa kwesikali sebhentshi kwakuyisiqalo, okuhloswe ngaso ekuqaleni ukuhlola amandla enqubo yokucwilisa komoya-mpilo. Okulandelayo, ukuhlolwa kwe-semi-industrial kusebenze njengebhuloho phakathi kwelabhorethri kanye nokuqaliswa okuphelele kwezimboni, okuhlinzeka ngemininingwane esebenzayo eyengeziwe. Ekugcineni, ukuhlolwa kwezimboni kwaqinisekisa ukusebenza kahle kwenqubo ngaphansi kwezimo zangempela zokukhiqiza zomhlaba.
Imiphumela yokuhlola
Ibhentshi - Isikali Sokulinga
Imiphumela yokuhlolwa kwesikali sebhentshi ibonise ukuthi inqubo yokucwiliswa komoya-mpilo enothile ingakhuphula izinga lokucwiliswa kwegolide ngo-0.30%. Le mpumelelo yokuqala ikhombise ukusebenza kobuchwepheshe.
I-Semi-industrial Experiment
Ngesikhathi sokuhlolwa kwe-semi-industrial, kwabonakala ukuthi izinga lokucwiliswa kwegolide laliphezulu kakhulu uma liqhathaniswa nenqubo yokukhishwa komoya. Lokhu kushesha kwejubane le-leaching kwakuyinkomba enamandla yokuphakama kwenqubo yokucwilisa komoya-mpilo.
Ukuhlolwa Kwezimboni
Uhlolo lwezinyanga ezintathu lwezimboni lwaqinisa izinzuzo zokucwiliswa komoya-mpilo onothile. Uma kuqhathaniswa nenqubo evamile ye-air-leaching, inqubo ye-leaching enothile nge-oxygen ayizange nje ikhulise izinga le-leaching ngo-0.18% kodwa futhi yasheshisa kakhulu isivinini sokuvuza. Ukwengeza, izinga lesiliva endaweni esele ye-leaching lehle ngo-5×10⁻⁶ - 6×10⁻⁶. Ngokomnotho, inzuzo yezomnotho yaminyaka yonke ikhuphuke ngama-yuan ayizigidi ezingu-4.901, okugqamisa izinzuzo ezinkulu zezezimali ezihlobene nenqubo entsha.
Isiphetho
Lolu cwaningo mayelana nenqubo yokungenisa umoya-mpilo enomfutho womoya osemkhathini luzuze imiphumela emihle kakhulu yezomnotho nezobuchwepheshe. Okutholiwe kungasebenza njengesithenjwa esibalulekile samabhizinisi egolide afuna ukuthuthukisa izinqubo zawo ze-cyanidation leaching. Ngaphezu kwalokho, lolu cwaningo lunomthelela ekuthuthukisweni kobuchwepheshe be-cyanidation leaching, okuvula amathuba amasha emboni yezimayini zegolide ukuthuthukisa ukusetshenziswa kwezinsiza kanye nokwenza inzuzo.
