Iko Kukosha uye Kuchengetedza Kutarisira kweSodium Cyanide muIndasitiri yeMigodhi

ziviso

Mu Mining Indasitiri, Sodium Cyanide inoita basa rakakosha mukutorwa kwesimbi dzinokosha, kunyanya goridhe nesirivha. Nekudaro, chimiro chayo chine chepfu zvakanyanya chinoda kuomarara Safety Management kuve nechokwadi chekugara zvakanaka kwevashandi, kuchengetedza zvakatipoteredza, uye kuchengetedza kushanda kwakasimba kwemabasa emigodhi.

Kukosha kweSodium Cyanide muMigodhi

Kuchera Goridhe neSirivha

Kunyanya kushandiswa kwe sodium cyanide mumigodhi iri muchirongwa checyanidation chekuchera goridhe nesirivha. Ndarama nesirivha zvinowanzoitika mune yakaderera - giredhi ores, uye cyanide inoumba simbi inonyungudika nesimbi dzinokosha idzi. Muhupo hweokisijeni nemvura, Sodium cyanide inopindirana negoridhe kana sirivheri mune ore, ichiita simbi - cyanide complex ion, se[Au(CN)₂]⁻ kana [Ag(CN)₂]⁻. Iyi yakaoma inogona kubva yapatsanurwa zviri nyore kubva kune ore matrix, kazhinji kuburikidza nemaitiro eadsorption pane activated kabhoni kana nekushandisa dzimwe nzira dzemakemikari kuti uwedzere kucheneswa.

Mutengo - kubudirira

Kuenzaniswa nedzimwe nzira dzekubvisa, iyo cyanidation process uchishandisa sodium cyanide inodhura - inoshanda. Inobvumira kutorwa kwesimbi dzinokosha kubva kune dzakasiyana siyana dzemhando dzeore, kusanganisira iyo ine yakaoma mineralogy. Kudhura uku kunoita kuti makambani emigodhi akwanise kushanda zvine pundutso, kunyanya paanenge achibata mabasa ezvicherwa zvakakura uko kunokwanisa kuwaniswa upfumi hwenyika.

High Recovery Rates

Kana ikashandiswa nemazvo, iyo cyanidation process inogona kuwana yakakwirira kudzoreredza mitengo yegoridhe nesirivha. Nekugadzirisa mamiriro akaita sepH, cyanide concentration, uye kuwanikwa kweokisijeni, makambani emigodhi anogona kutora chikamu chikuru chesimbi dzinokosha dziri mu ore. Kudzoreredza kwakakwira hakungo wedzera pundutso yebasa rekuchera migodhi chete asiwo kunobatsira mukushandiswa nemazvo kwezviwanikwa zvishoma.

Kuchengetedzwa Kwekuchengetedza kweSodium Cyanide muMigodhi

Kuteerera Kwemitemo

Makambani emigodhi anofanirwa kunyatsotevedzera mirau yemuno, yenyika, neyepasirese maererano nekushandiswa, kuchengetedza, uye kutakura kwesodium cyanide. Iyi mirau inowanzo vhara zvinhu zvakaita seyakanyanya kubvumidzwa cyanide kunyura mumvura yetsvina, kunyora kwakaringana uye kurongedzerwa kwezvinhu zvecyanide, uye zvinodiwa zvekuchengetedza kudzidziswa kwevashandi vanobatanidzwa mumabasa ane chekuita necyanide. Kutevedzwa nemirau iyi haingori chisungo chemutemo chete asiwo inhanho yakakosha mukuona kuchengetedzwa.

Kuchengetedza Zvivakwa

Sodium cyanide inofanira kuchengetwa munzvimbo dzakatsaurirwa, dzakagadzirwa zvakanaka. Zvivako izvi zvinofanirwa kuvakwa nezvinhu zvisingaite ngura ne cyanide solutions. Dzinofanirwawo kunge dziri munzvimbo dziri kure nenzvimbo dzinogara vanhu, zvitubu zvemvura, uye dzimwe nzvimbo dzakaoma. Matangi ekuchengetera uye midziyo inofanirwa kuve neinovuza - yekuona masisitimu uye chechipiri chemukati zvimiro kudzivirira kuburitswa kwecyanide kana yekutanga mudziyo kutadza.

Kufambisa Kwekuchengetedza

Panguva yekufambisa, sodium cyanide inofanira kutakurwa maererano nemitemo yakasimba. Mota dzekutakura dzakakosha dzinodiwa, dzakagadzirirwa kuderedza njodzi yekuteuka uye tsaona. Mota idzi dzinofanirwa kunge dzakashongedzerwa makiti emhinduro dzechimbichimbi, kusanganisira maajenti ekubvisa cyanide. Nzira dzezvifambiso dzinofanirwa kunyatsorongwa kudzivirira nzvimbo dzakakwirira - dzemotokari uye nzvimbo dzine mukana mukuru wekukuvadza kwezvakatipoteredza kana pakaitika tsaona.

Kudzidziswa kwevashandi uye Kuchengeteka

Vese vashandi vanobatanidzwa mukubata sodium cyanide vanofanirwa kuwana kudzidziswa kwekuchengetedza kwakadzama. Kudzidziswa uku kunofanirwa kuvhara zvimiro zvesodium cyanide, kusanganisira huturu hwayo, mabatiro akachengeteka uye kuendesa cyanide mhinduro, uye kushandiswa kwakakodzera kwemidziyo yekuzvidzivirira (PPE). Vashandi vanofanira kudzidziswa nzira dzekupindura nechimbichimbi, sekuti vangapindura sei pakuteuka kwecyanide kana nyaya yekufumurwa kwecyanide. Nguva dzose kudzidzira kuchengetedza kunofanirwa kuitwa kuti kuve nechokwadi chekuti vashandi vakanyatsogadzirira chero zvingaitika zviitiko.

Tupuka Management

Indasitiri yezvicherwa inogadzira huwandu hwakawanda hwecyanide - ine tsvina. Kutarisira tsvina kwakakodzera kwakakosha kudzivirira kuburitswa kwecyanide munzvimbo. Mvura yakasviba ine cyanide inofanira kurapwa kuderedza cyanide concentration kusvika kumazinga anogamuchirwa asati abuda. Nzira dzekurapa dzinogona kusanganisira makemikari oxidation, biological treatment, kana musanganiswa wezvose. Tsvina dzakasimba, dzakaita semaswe, dzinofanirawo kuchengetedzwa nenzira inoderedza njodzi yekunyura kwe cyanide muvhu rakapoteredza nemvura.

mhedziso

Sodium cyanide chinhu chakakosha muindasitiri yezvicherwa, zvichiita kuti simbi dzinokosha dzibviswe nenzira inoshanda uye inodhura. Nekudaro, huturu hwayo hunoda kutevedzwa kwemaitiro akasimba ekuchengetedza kuchengetedza. Nekusimbisa Kuteerera Kwemitemo, kuchengetedza kwakakodzera, kutakura, kudzidziswa kwevashandi, nekugadzirisa marara, indasitiri yemigodhi inogona kuramba ichishandisa sodium cyanide ichideredza njodzi dzinobatanidzwa kune hutano hwevanhu uye zvakatipoteredza.
