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

Emkhakheni we izimayini zegolide, ukuphishekela ubuchwepheshe bokumba obusebenzayo nobungabizi kakhulu bekulokhu kungumfutho oyinhloko wokuthuthukisa imboni. Ubuchwepheshe be-heap leaching, ikakhulukazi inqubo esetshenziswayo I-Sodium Cyanide njenge-ejenti ye-leaching, kancane kancane iba yisinqumo esibalulekile ezinkampanini eziningi zezimayini zegolide ukuze zizuze inzuzo ephansi nephezulu.

I-Heap Leaching: I-Revolutionary Wet Metallurgy Technology

Ukukhishwa kwenqwaba, njenge-a i-metallurgy emanzi ubuchwepheshe, bulethe izinguquko eziningi ezimayini zegolide. Ngokwesiko, ukwakha kanye nokunikeza amalayisense efekthri ukuze kucutshungulwe izinsiza ezimbiwayo ngokuvamile kudinga isikhathi eside sokulungiselela okungenani iminyaka eyishumi, siphelezelwa yimali enkulu yokutshalwa kwezimali. Lokhu ngokungangabazeki kuyinselelo enkulu emabhizinisini amaningi okumba igolide, ikakhulukazi amabhizinisi amancane naphakathi nendawo. Kodwa-ke, ukuvela kobuchwepheshe be-heap leaching kuphule lo mgomo. Izindleko zayo zokusebenza ziphansi kakhulu kunezobuchwepheshe obujwayelekile bokucubungula, okunikeza indlela elula nephansi - yezindleko zokumbiwa kwegolide.

Iqhaza Elibalulekile Le-Sodium Cyanide Ku-Heap Leaching

I-sodium cyanide idlala indima ebalulekile kubuchwepheshe bokukhipha inqwaba. Ingasabela ngamakhemikhali nezinto zegolide ezitsheni zegolide, incibilikise igolide elisuka ezitsheni ezinsimbi bese ngaleyo ndlela inikeze amandla ukukhishwa okuphumelelayo. Amabhizinisi amaningi ezimayini zegolide azuze izinzuzo ezinkulu zezomnotho ngokwamukela i i-sodium cyanide heap leaching ubuchwepheshe bokukhipha.

Ikesi 1: Imayini yegolide yakwaCarlin eNevada, e-USA

Thatha iCarlin Gold Mine eseNevada, e-USA njengesibonelo. Ngaphambi kokufaka isicelo i-sodium cyanide ubuchwepheshe be-heap leaching, imayini ibhekane nenkinga yezindleko eziphezulu zezimayini kanye namazinga aphansi okubuyisela emuva. Ngemva kokwamukela lobu buchwepheshe, ukusebenza kahle kwezimayini zemayini yegolide kuye kwathuthukiswa kakhulu. I-Carlin Gold Mine ivuza inqwaba ensimbi echotshoziwe emayini yomgodi ovulekile, ifafaze inqwaba yensimbi ngensimbi. I-sodium cyanide isisombululo sokuncibilikisa igolide ekhambi. Ngemva kochungechunge lwezindlela zokwelapha ezalandela, izinga lokutholwa kwegolide linyuswe ngempumelelo, futhi izindleko zokucubungula ngethani ngalinye lensimbi yehlisiwe. Ngokwezibalo, ngemva kokusebenzisa lobu buchwepheshe, izindleko zokukhiqiza zeCarlin Gold Mine ziye zancishiswa cishe ngama-30%, kanti ukukhiqizwa kwegolide kuye kwanda kakhulu, okuletha inzuzo ecebile 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 inqwaba ye-sodium cyanide heap leaching abuthuthukisi nje ukusebenza kahle kwezimayini zegolide kodwa futhi kunciphisa kakhulu izindleko. Le ndlela - efakazelwe kahle futhi enezindleko - esebenzayo yokukhipha insimbi eyigugu iye yamukelwa kabanzi yizinkampani ezinkulu nezincane zezimayini zegolide. Ekwakhiweni nasekunwetshweni kwezimayini ezintsha, ubuchwepheshe be-sodium cyanide heap leaching nalo bucatshangelwa ngokwandayo. Ihlinzeka ngesisombululo esisebenziseka kalula sokukhipha igolide kubakhiqizi begolide, okubenza bakwazi ukufaka izimpahla ngokushesha ekukhiqizweni, okuthuthukisa kakhulu ukuncintisana kwemakethe wamabhizinisi ezimayini zegolide kanye nokuletha amathuba amasha entuthuko embonini yezimayini zegolide. Ngokuthuthukiswa okuqhubekayo kanye nokuthuthukiswa kobuchwepheshe, ubuchwepheshe be-sodium cyanide heap leaching kulindeleke ukuthi bubambe iqhaza elibaluleke nakakhulu ekumbiweni kwegolide esikhathini esizayo, ukusiza amabhizinisi amaningi ezimayini zegolide ukuthi afinyelele umgomo wokuthuthukiswa wezindleko eziphansi kanye nembuyiselo ephezulu.
