Kugwiritsa Ntchito ndi Ubwino Wama Reagents mu Gold Mine Cyanidation Process

Kupaka utoto wa golide mu migodi ya golide ndi njira yomwe imagwiritsidwa ntchito kwambiri popaka utoto wa golide, yomwe imagwiritsidwa ntchito kwambiri chifukwa cha luso lake lapamwamba komanso makhalidwe ake azachuma. Nkhaniyi ipereka chiyambi chatsatanetsatane cha kugwiritsa ntchito reagent ndi ubwino wake mu njira yopaka utoto wa golide mu migodi ya golide , kukuthandizani kumvetsetsa bwino ukadaulo uwu wopaka utoto.

I. Chidule cha Cyanidation

Cyanidation ndi njira yopangira miyala yomwe imatulutsa golide kuchokera ku miyala pogwiritsa ntchito cyanide solution. Malinga ndi makhalidwe a miyala ndi zofunikira za kupanga miyala, cyanidation ingagawidwe m'magulu awiri akuluakulu: Agitation cyanidation ndi Percolation cyanidation . Agitation cyanidation imagwiritsidwa ntchito makamaka pochiza ma flotation gold concentrates kapena zonse - slime cyanidation, pomwe percolation cyanidation imagwiritsidwa ntchito makamaka pochiza ma ores okhala ndi golide wochepa.

II. Kugwiritsa ntchito sodium cyanide

Sodium cyanide ndi imodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri popanga cyanidation. Ntchito yake yayikulu ndikusungunula golide mu yankho la cyanide kuti apange golide wosungunuka - cyanide complexes. Kugwiritsa ntchito Sodium cyanide ndikosavuta komanso kothandiza. Komabe, mavuto ake a poizoni ndi kuipitsa chilengedwe sanganyalanyazidwe. Pofuna kuthana ndi izi, Xinhai Mining Technology Co., Ltd. yapanga chotsukira golide chachilengedwe kuti chilowe m'malo mwa Sodium Cyanide pochotsa golide wa cyanide. Chotsukira ichi sichimangokhala ndi njira yofanana yogwiritsira ntchito ndi sodium cyanide , komanso chimakhala ndi liwiro lobwezeretsa mwachangu, liwiro lotulutsa madzi ambiri, komanso mtengo wotsika.

III. Kugwiritsa ntchito Reagent mu Agitation Cyanidation

The golide m'zigawo ndondomeko mukubwadamuka cyanidation makamaka zikuphatikizapo mitundu iwiri ya flowsheets: mmodzi ndi mosalekeza potsimikizira - kutsuka panopa, ndi cyanidation - nthaka m'malo ndondomeko (CCD njira ndi CCF njira) kuti achire golide m'malo ndi precipitating ndi nthaka ufa (waya); ina ndi fyuluta - free cyanide carbon - mu - zamkati ndondomeko (CIP njira ndi CIL njira) kuti mwachindunji adsorbs ndi achire golide ku cyanide zamkati ntchito adamulowetsa mpweya popanda kusefera ndi kuchapa. Munjira izi, sodium cyanide kapena wokometsera golide wokometsera golide ndiye chinthu chofunikira kwambiri. Kuphatikiza apo, ma reagents othandizira monga zinc ufa ndi activated carbon amafunikanso.

IV. Kugwiritsa ntchito Reagent mu Percolation Cyanidation

Percolation cyanidation ndi yoyenera ma depositi a placer ndi zida zotayirira komanso porous. Njira zodziwika bwino zimaphatikizapo kukhetsa matanki ndi kukhetsa milu. Njira yodulira milu imakhala yotsika mtengo yopangira, imatha kukhala masikelo osiyanasiyana, ndipo imakhala yosinthika kwambiri. Panthawi yokhetsa milu, cyanide leaching solution imatulutsa golide kuchokera ku miyala yamtengo wapatali kudzera mu kupopera kapena kupukuta. The leaching solution imabwerezedwanso kangapo ndikupopera pa mulu wa miyalayo mobwerezabwereza. Kenako, yankho la leaching limasonkhanitsidwa ndikuthandizidwa ndi ayoni - kusinthana utomoni, activated carbon adsorption, kapena zinc ufa (waya) m'malo. Sodium cyanide kapena wokometsera golide wotengera zachilengedwe amatenga gawo lalikulu pakuchita izi.

V. Ubwino wa Othandizira Kuvala Ore Osateteza zachilengedwe

Poganizira zovuta za sodium cyanide ndi zomwe zikuchitika pano zachilengedwe, Xinhai Mining Technology Co., Ltd. Chovala ichi cha ore sichingangolowetsa m'malo mwa sodium cyanide, komanso chimakhala ndi izi:

1. Kubwezeretsa mwachangu : Chotsukira miyala chomwe sichiwononga chilengedwe chimakhala ndi liwiro lotulutsa golide mwachangu, chomwe chingatulutse golide kuchokera mu miyalayo m'kanthawi kochepa ndikuwonjezera magwiridwe antchito opangira.

2. Kuchuluka kwa kuchotsedwa kwa golide : Kuchuluka kwa kuchotsedwa kwa chitsulo chosungira golide chomwe sichiwononga chilengedwe ndi kwakukulu kuposa kwa sodium cyanide yachikhalidwe, yomwe imatha kupeza golide kuchokera ku chitsulocho mokwanira ndikuwonjezera kugwiritsa ntchito bwino chuma.

3. Mtengo wotsika : Mtengo wogwiritsa ntchito chotsukira miyala choteteza chilengedwe ndi wotsika kuposa wa sodium cyanide, zomwe zingathandize kuchepetsa ndalama zopangira ndikuwonjezera phindu pazachuma.

4. Wochezeka komanso wopanda kuipitsa chilengedwe : Chotsukira miyala chochezeka ndi chopanda poizoni komanso chopanda vuto, chochezeka ku chilengedwe, chimakwaniritsa zofunikira pakali pano, ndipo chimachepetsa kuipitsa chilengedwe.

VI. Mapeto

Kugwiritsiridwa ntchito kwa reagent mu ndondomeko ya golide ya cyanidation ndi ulalo wofunikira paukadaulo wovala wa ore. Sodium cyanide ndi wovala golide wokonda zachilengedwe amatenga gawo lofunikira munjira zosiyanasiyana za cyanidation. Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kugogomezera kwambiri pachitetezo cha chilengedwe, kukulitsa ndi kugwiritsa ntchito zida zowongolera bwino komanso zoteteza zachilengedwe kudzakhala chitsogozo chofunikira pakukula kwa msika wamigodi wa golide.
