Zotsika - Mtengo, Wapamwamba - Kubwerera: Ukadaulo wa Sodium cyanide Heap Leaching Umapatsa Mphamvu Kugola Golide

Pankhani ya migodi ya golide , kufunafuna ukadaulo wothandiza komanso wokwera mtengo wochotsera golide kwakhala chinthu chofunikira kwambiri pakukula kwa makampaniwa. Ukadaulo wochotsa golide m'mabokosi, makamaka njira yogwiritsira ntchito Sodium Cyanide ngati wothandizira kuchotsa golide, pang'onopang'ono ukukhala chisankho chachikulu kwa mabizinesi ambiri ochotsa golide kuti apeze phindu lotsika mtengo komanso lokwera mtengo.

Heap Leaching: A Revolutionary Wet Metallurgy Technology

Kuchotsa miyala yamtengo wapatali, monga ukadaulo wogwiritsa ntchito zitsulo zonyowa , kwabweretsa kusintha kwakukulu pa migodi ya golide. Mwachikhalidwe, kumanga ndi kupereka chilolezo ku fakitale yogwiritsira ntchito zinthu zomwe zachotsedwa m'migodi nthawi zambiri kumafuna nthawi yayitali yokonzekera ya zaka zosachepera khumi, limodzi ndi ndalama zambiri zogulira. Izi mosakayikira ndi vuto lalikulu kwa mabizinesi ambiri akumigodi ya golide, makamaka mabizinesi ang'onoang'ono ndi apakatikati. Komabe, kubuka kwa ukadaulo wochotsa miyala yamtengo wapatali kwathetsa vutoli. Mtengo wake wogwirira ntchito ndi wotsika kwambiri kuposa wa ukadaulo wachikhalidwe wopangira, zomwe zimapangitsa kuti migodi ya golide ikhale yosavuta komanso yotsika mtengo.

Udindo Wofunikira wa Sodium Cyanide mu Mulu Leaching

Sodium cyanide imagwira ntchito yofunika kwambiri paukadaulo wochotsa miyala yamtengo wapatali. Imatha kuchita zinthu pogwiritsa ntchito mankhwala ndi zinthu zagolide zomwe zili mu miyala yamtengo wapatali yagolide, kusungunula golide kuchokera mu miyala yamtengo wapataliyo ndikupangitsa kuti ichotsedwe bwino. Makampani ambiri ofukula golide apeza phindu lalikulu pazachuma potengera ukadaulo wochotsa miyala yamtengo wapatali ya sodium cyanide.

Mlandu 1: Mgodi wa Golide wa Carlin ku Nevada, USA

Mwachitsanzo, mgodi wa Carlin Gold Mine womwe uli ku Nevada, USA usanayambe kugwiritsa ntchito ukadaulo wa sodium cyanide heap leaching, mgodiwu unakumana ndi vuto la ndalama zambiri zogulira migodi komanso ndalama zochepa zobweza. Pambuyo pogwiritsa ntchito ukadaulo uwu, mphamvu ya mgodi wagolide yakhala ikuyenda bwino kwambiri. Mgodi wa Carlin Gold Mine umayendetsa heap leaching pa miyala yophwanyika mumgodi wotseguka, kupopera mulu wa miyala ndi yankho la Sodium cyanide mumtsuko kuti usungunule golide mu yankho. Pambuyo pa chithandizo chotsatira, kuchuluka kwa golide komwe kumabwezedwa kwawonjezeka bwino, ndipo mtengo wokonza pa tani imodzi ya miyala wachepetsedwa. Malinga ndi ziwerengero, pambuyo pogwiritsa ntchito ukadaulo uwu, mtengo wopangira Mgodi wa Carlin Gold wachepetsedwa ndi pafupifupi 30%, pomwe kupanga golide kwawonjezeka kwambiri, zomwe zimapangitsa kuti bizinesiyo ipeze phindu lalikulu.

Mlandu 2: Migodi Yaing'ono Yagolide ku Kyrgyzstan

M’migodi ina yaing’ono ya golide ku Kyrgyzstan, amapindulanso ndi ukadaulo wa sodium cyanide heap leaching. Chifukwa cha ndalama zochepa, migodi ya golide yaing'onoyi singakwanitse kuchita zachikhalidwe komanso zovuta zochotsa golide. Kukhazikitsidwa kwaukadaulo wa sodium cyanide heap leaching kwawathandiza kuti ayambe ntchito zamigodi pamtengo wotsika. Mwachitsanzo, mgodi wawung'ono wa golide watulutsa bwino golide kuchokera ku miyala yamtengo wapatali pomanga milu yotayira pamalo osavuta komanso kugwiritsa ntchito sodium cyanide solution pobowoleza miyalayo. Ngakhale kuti ndalama zoyambilira ndizochepa, ndi kupita patsogolo kopanga, ndalama za mgodi wa golidi uyu zikuchulukirachulukira chaka ndi chaka.

Ubwino ndi Tsogolo la Sodium Cyanide Heap Leaching Technology

Ukadaulo wochotsa sodium cyanide heap leaching sumangowonjezera luso la migodi ya golide komanso umachepetsa kwambiri ndalama. Njira yodziwika bwino komanso yotsika mtengo yochotsera zitsulo zamtengo wapatali iyi yagwiritsidwa ntchito kwambiri ndi makampani osiyanasiyana akuluakulu ndi ang'onoang'ono akumigodi ya golide. Pakupanga ndi kukulitsa migodi yatsopano, ukadaulo wochotsa sodium cyanide heap leaching ukuganiziridwanso kwambiri. Umapereka njira yabwino yochotsera golide kwa opanga golide, zomwe zimawathandiza kuyika zinthu mwachangu popanga, zomwe zimawonjezera mpikisano pamsika wamakampani akumigodi ya golide ndikubweretsa mwayi watsopano wopititsa patsogolo makampani akumigodi ya golide. Ndi kukhathamiritsa kosalekeza ndi kukonza ukadaulo, ukadaulo wochotsa sodium cyanide heap leaching ukuyembekezeka kukhala ndi gawo lofunika kwambiri pakukumba golide mtsogolo, kuthandiza makampani ambiri akumigodi ya golide kukwaniritsa cholinga chokweza ndalama zotsika mtengo komanso zokwera mtengo.
