Izvo Zvinonyanya Kubatsira zveSodium Cyanide Heap Leaching yekubvisa Goridhe

Sodium cyanide heap leaching inzira inoshandiswa zvakanyanya muindasitiri yekuchera goridhe yekuchera goridhe kubva kune yakaderera-giredhi ores. Kuita uku kunosanganisira kututira matombo egoridhe akaderera-giredhi kana kuti mitsara padhidhi uye kumwaya mushonga wecyanide pamusoro pemurwi kunyungudutsa goridhe nesirivheri, kugadzira mhinduro ine goridhe yekuzopora. Heano mabhenefiti makuru eiyi tekinoroji:

Mutengo - kubudirira

1.Low capital investment: Imwe yemabhenefiti akakosha e Sodium cyanide heap leaching ndiyo yakaderera capital capital inodiwa. Kuenzaniswa nedzimwe nzira dzakaomarara dzekuchera goridhe senge chigayo nekunyungudutsa, izvo zvinoda hupfumi hwakasimba nemidziyo, murwi wekucheka unongoda zvivakwa zvakakosha senge leaching pad, nzira yekuunganidza mhinduro, uye nzira yekutenderera kwemhinduro. Hapana chikonzero chekuvaka zvirimwa zvakakura uye zvinodhura zvekugadzirisa, izvo zvinoita kuti ive sarudzo inokwezva, kunyanya kune zviduku-kusvika-pakati-zvakakura zvekuchera migodhi kana kuti zvicherwa zvicherwa zvine zviwanikwa zvishoma.

2.Kuderedza mari yekushandisa:

• Low simba rakawanda: Nzira yekubvisa mirwi ine simba shoma rinodiwa. Izvo hazvisanganisire yakakwirira - simba - rakasimba mashandiro sekukuya ores kune yakatsetseka poda muguyo rebhora, izvo zvinowanzoitika mune dzimwe nzira dzekubvisa. Iko kushanda kuri nyore kwemhinduro yekupfapfaidza uye percolation kuburikidza nemurwi weore inoda simba shoma, zvichiita kuti simba ridzike.

• Mari yakaderera reagent (zvinoenderana nedzimwe nzira): Kunyangwe cyanide iri kiyi reagent uye kubata kwayo kunoda matanho ekuchengetedza akasimba, maererano nehuwandu hwekubvisa goridhe, huwandu hwecyanide hunodiwa pamurwi leaching hunogona kuvandudzwa. Kana ichienzaniswa nemamwe maajenti ekubvisa goridhe, cyanide inogona kudhura-inoshanda mune mamwe mamiriro ezvinhu, kunyanya tichitarisa huwandu hwakakura hwegiredhi ores anogona kugadziriswa uchishandisa nzira iyi.

Kukodzera kune yakaderera-giredhi ores

1.Economical kutorwa kubva pasi-giredhi deposits: Sodium cyanide heap leaching inonyanya kunyatso-inokodzera kurapa yakaderera-giredhi ores egoridhe, kazhinji ayo ane mamakisi anotangira pa0.5 - 3g/t. Izvi zvakawedzera zvakanyanya huwandu hwehupfumi hwegoridhe zviwanikwa. Kare, madhipoziti mazhinji egiredhi yakaderera aionekwa seasina hupfumi kune yangu. Nekudaro, nekuvandudzwa kwehunyanzvi hwekuita murwi, madhipoziti aya zvino anogona kushandiswa zvine pundutso. Semuyenzaniso, mune mamwe matunhu ane madhipoziti makuru, egiredhi repamusoro ari kushomeka, kucherwa kwegoridhe kubva mumatombo egiredhi yakaderera kuburikidza nekucheneswa kwemirwi kwave kunonyanya kugadzira goridhe.

2.Kushandiswa kwezviwanikwa zvisati zvamboshandiswa: Inobvumira kushandiswa kwemhando dzakasiyana-siyana dzezviwanikwa zvisati zvamboshandiswa, zvakadai semarara emugodhi, kusanganisira miswe kubva pakucherwa kwekare uye zvicherwa zvakaderera zvakasiiwa panguva yekuchera. Nekugadzirisa zvinhu izvi, kwete chete kuti imwe goridhe inogona kudzoserwa, asi inobatsirawo mukudzikisa tsoka yezvakatipoteredza ine chekuita nekuchengetedza huwandu hwakawanda hwemarara.

Maitiro ari nyore

1.Kusununguka kwekushanda: Iyo mirwi leaching process iri nyore mukushanda kwayo. Kana murwi weore wavakwa padhidhi rakagadzirirwa leaching, basa guru rinosanganisira kuramba vachimwaya mushonga wecyanide pamusoro pemurwi. Maitirwo acho haadi vanhu vane hunyanzvi hwekuita mabasa ezuva nezuva. Vashandi vanogona kudzidziswa nekukasira kuita mabasa akadai sekupfapfaidza kwemhinduro, kuongorora mafambiro ekuyerera, uye kuunganidza sampuli. Kureruka uku kunobatsirawo kudzikisira mitengo yevashandi ine chekuita nekudzidziswa uye kuhaya vashandi vane hunyanzvi.

2.Mashoma ekugadzirisa matanho: Kuenzaniswa nemaitiro akaomarara ekuchera goridhe, murwi leaching ine mashoma matanho ekugadzirisa. Iko hakuna kudikanwa kwemaitiro akajeka ekuparadzanisa zvicherwa senge froth flotation, iyo inosanganisira akawanda matanho ekuwedzera akasiyana reagents kuparadzanisa goridhe - inotakura zvicherwa kubva kune gangue zvicherwa. Mumurwi wekucheka, mushonga wecyanide unobata zvakananga ore iri mumurwi, kunyungudutsa goridhe nesirivheri, kurerutsa maitiro ese ekubvisa.

Kufambira mberi kwetekinoroji kunowedzera kushanda zvakanaka

1.Improved agglomeration maitiro: Kuvandudzwa kwemaitiro ekugadzirisa agglomeration kwakawedzera zvakanyanya kushanda kwe Sodium cyanide murwi leaching. Kune zvicherwa zvisingapindike zvakanaka kana kuti ivhu rakawanda, kuungana kunogona kushandiswa kunatsa kuyerera kwemushonga wecyanide kuburikidza nemurwi weore. Nekuwedzera mabhainda akadai seraimu kana Portland simende kune ore uyezve kunyorova uye nemuchina agglomerating musanganiswa, kuumbwa kwenzira dzemhinduro percolation kunosimudzirwa. Izvi zvinokonzeresa kubatana kwakasimba pakati peiyo cyanide mhinduro uye goridhe-inotakura zvicherwa, zvichikonzera kuwedzera kudzoreredza goridhe mitengo.

2.Kushandiswa kwezvinowedzera kuwedzera leaching: Kuwedzerwa kwezvimwe zvekuwedzera kunogona kuwedzera kuvandudza maitiro ekusiya. Semuenzaniso, kushandiswa kweokisijeni - kuburitsa maajenti senge okisijeni yakachena kana calcium peroxide inogona kuwedzera iyo oxidation mukana weiyo leaching mhinduro, ichiwedzera kunyungudika kwegoridhe. Pamusoro pezvo, pamusoro - anoshanda maajenti anogona kuwedzerwa kunatsiridza kunyorova kweiyo ore zvimedu necyanide mhinduro, kuvandudza iyo yakazara leaching kunyatsoita. Kufambira mberi kwehunyanzvi uku kwaita Sodium Cyanide mirwi yekucheka yakatonyanya kushanda uye inoshanda mukubvisa goridhe kubva kumhando dzakasiyana dzeores.
