Okuphansi - Izindleko, Eziphakeme - Ukubuya: I-Sodium cyanide Heap Leaching Technology Inika Amandla Ezimayini Zegolide

Emkhakheni wokumba igolide , ukuphishekela ubuchwepheshe bokukhipha obusebenza kahle futhi obungabizi kakhulu bekulokhu kuyimbangela ebalulekile yokuthuthukiswa kwemboni. Ubuchwepheshe bokukhipha inqwaba, ikakhulukazi inqubo esebenzisa i-Sodium Cyanide njenge-ejenti yokukhipha igolide, kancane kancane buba yinto eyinhloko emabhizinisini amaningi okumba igolide ukuze athole imbuyiselo ephansi nephezulu.

I-Heap Leaching: I-Revolutionary Wet Metallurgy Technology

Ukuhlanza i-heap leaching, njengobuchwepheshe be -wet metallurgy , kulethe izinguquko eziningi ekumbeni igolide. Ngokwesiko, ukwakha nokunikeza ilayisense ifektri yokucubungula izinsiza ezimbiwe kuvame ukudinga isikhathi eside sokulungiselela okungenani iminyaka eyishumi, okuhambisana nokutshalwa kwezimali okukhulu. Lokhu ngokungangabazeki kuyinselele enkulu emabhizinisini amaningi okumba igolide, ikakhulukazi amabhizinisi amancane naphakathi. Kodwa-ke, ukuvela kobuchwepheshe bokuhlanza i-heap leaching kuqede lesi sidingo. Izindleko zayo zokusebenza ziphansi kakhulu kunezobuchwepheshe bokucubungula bendabuko, okunikeza indlela elula nengabizi kakhulu yokumba igolide.

Iqhaza Elibalulekile Le-Sodium Cyanide Ku-Heap Leaching

I-sodium cyanide idlala indima ebalulekile kubuchwepheshe bokukhipha inqwaba. Ingasabela ngamakhemikhali nezinto zegolide ezitsheni zegolide, ichithe igolide ezitsheni zegolide ngaleyo ndlela ivumele ukukhishwa okuphumelelayo. Amabhizinisi amaningi okumba igolide athole izinzuzo ezinkulu kwezomnotho ngokusebenzisa ubuchwepheshe bokukhipha inqwaba ye-sodium cyanide .

Ikesi 1: Imayini yegolide yakwaCarlin eNevada, e-USA

Thatha iCarlin Gold Mine eseNevada, e-USA njengesibonelo. Ngaphambi kokusebenzisa ubuchwepheshe bokuhlanzwa kwe -sodium cyanide heap, imayini ibhekane nenkinga yezindleko eziphezulu zokumba kanye namazinga aphansi okubuyisa. Ngemva kokusebenzisa lobu buchwepheshe, ukusebenza kahle kokumba kwemayini yegolide kuthuthukiswe kakhulu. I-Carlin Gold Mine yenza ukuhlanzwa kwe-heap kuma-ore achotshoziwe emayini evulekile, ifafaza i-ore mount ngesisombululo se -Sodium cyanide ukuze incibilikise igolide esixazululweni. Ngemva kochungechunge lwezindlela zokwelapha ezilandelayo, izinga lokubuyisa igolide likhushulwe ngempumelelo, futhi izindleko zokucubungula ngethani le-ore zincishisiwe. Ngokwezibalo, ngemuva kokusebenzisa lobu buchwepheshe, izindleko zokukhiqiza ze-Carlin Gold Mine zincishisiwe cishe ngo-30%, kuyilapho ukukhiqizwa kwegolide kukhuphuke kakhulu, okuletha inzuzo eningi ebhizinisini.

Icala 2: Izimayini Zegolide Ezincane e-Kyrgyzstan

Kwezinye izimayini zegolide ezincane e-Kyrgyzstan, bayazuza futhi kubuchwepheshe be-sodium cyanide heap leaching. Ngenxa yezimali ezilinganiselwe, lezi zimayini zegolide ezincane azikwazi ukukhokhela inqubo yendabuko kanye neyinkimbinkimbi yokukhipha igolide. Ukwethulwa kobuchwepheshe be-sodium cyanide heap leaching kubenze bakwazi ukuqala imisebenzi yezimayini ngezindleko eziphansi. Isibonelo, imayini encane yegolide ikhiphe ngempumelelo igolide kuma-ore esezingeni eliphansi ngokwakha inqwaba yezindawo zokulethela inqwaba endaweni elula futhi isebenzisa i-sodium cyanide solution ukuze ixove insimbi. Nakuba utshalomali lokuqala luncane uma kuqhathaniswa, nenqubekelaphambili eqhubekayo yokukhiqiza, imali engenayo yale mayini yegolide iye yanda unyaka nonyaka, okufeza inqubo yokuthuthukiswa kusukela kwezimayini ezincane kuya ekwandeni kancane kancane.

Izinzuzo kanye Namathemba Esikhathi esizayo we-Sodium Cyanide Heap Leaching Technology

Ubuchwepheshe bokukhipha i-sodium cyanide heap leaching abugcini nje ngokuthuthukisa ukusebenza kahle kokumba igolide kodwa futhi bunciphisa kakhulu izindleko. Le ndlela yokukhipha insimbi eyigugu efakazelwe kahle futhi engabizi kakhulu iye yamukelwa kabanzi yizinkampani ezahlukene ezinkulu nezincane zokumba igolide. Ekwakhiweni nasekukhuliseni izimayini ezintsha, ubuchwepheshe bokukhipha i-sodium cyanide heap leaching nabo bucatshangelwa kakhulu. Buhlinzeka ngesisombululo sokukhipha esisebenziseka kalula kubakhiqizi begolide, okubenza bakwazi ukufaka izimpahla ngokushesha ekukhiqizeni, okuthuthukisa kakhulu ukuncintisana kwemakethe kwamabhizinisi okumba igolide futhi kulethe amathuba amasha okuthuthukiswa embonini yokumba igolide. Ngokuthuthukiswa okuqhubekayo nokuthuthukiswa kobuchwepheshe, ubuchwepheshe bokukhipha i-sodium cyanide heap leaching kulindeleke ukuthi budlale indima ebaluleke kakhulu ekumbeni igolide esikhathini esizayo, kusize amabhizinisi amaningi okumba igolide afinyelele umgomo wokuthuthukiswa wenzuzo ephansi nephezulu.
