Kugwiritsa Ntchito ndi Ubwino Wama Reagents mu Gold Mine Cyanidation Process

Golide mine cyanidation ndi njira yomwe imagwiritsidwa ntchito kwambiri povala golide, yomwe imagwiritsidwa ntchito kwambiri chifukwa chakuchita bwino kwake komanso momwe chuma chikuyendera. Nkhaniyi ipereka chidziwitso chatsatanetsatane cha ntchito ya reagent ndi zabwino zake mu Gold Mine cyanidation ndondomeko, kukuthandizani kumvetsa bwino ore kuvala luso.

I. Chidule cha Cyanidation

Cyanidation ndi njira yovala ya ore yomwe imatulutsa golide kuchokera ku miyala kudzera mu a cyanide yankho. Malingana ndi momwe miyala yamtengo wapatali imayendera komanso zofunikira za kuvala kwa ore, cyanidation ikhoza kugawidwa m'magulu awiri akuluakulu: Kuchuluka kwa cyanidation ndi Percolation cyanidation. Agitation cyanidation imagwiritsidwa ntchito makamaka pochiza golide woyandama kapena zonse - cyanidation ya matope, pomwe percolation cyanidation imagwiritsidwa ntchito kwambiri pochiza ores otsika - oxidized golide - okhala ndi miyala.

II. Kugwiritsa ntchito sodium cyanide

Sodium cyanide ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri popanga cyanidation. Ntchito yake yayikulu ndikusungunula golide mu njira ya cyanide kupanga golide wosungunuka - cyanide complexes. Kugwiritsa ntchito Sodium cyanide ndi yosavuta komanso yothandiza. Komabe, kawopsedwe ake ndi zovuta zowononga chilengedwe sizinganyalanyazidwe. Pofuna kuthana ndi izi, Xinhai Mining Technology Co., Ltd. Sodium Cyanide m'zigawo za golide wa cyanide. Chovala ichi cha ore sichingokhala ndi njira yogwiritsira ntchito ngati sodium cyanide, koma ilinso ndi chiwongola dzanja chofulumira, chiwongola dzanja chokwera, 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. Kuchira msanga: Wovala zovala za ore wokonda zachilengedwe amakhala ndi liwiro lothamanga kwambiri, lomwe limatha kutulutsa golide mu nthawi yochepa ndikuwongolera kupanga bwino.

2. Mtengo wokwera kwambiri: Kutsika kwa zinthu zokometsera zokometsera zokometsera zachilengedwe ndizokwera kuposa za sodium cyanide yachikhalidwe, yomwe imatha kubweza golide m'matanthwe mokwanira ndikuwongolera kagwiritsidwe ntchito kazinthu.

3. Kutsika mtengo: Mtengo wogwiritsira ntchito wopangira zovala zokometsera zachilengedwe ndi wotsika kuposa wa sodium cyanide, womwe ungathe kuchepetsa mtengo wopangira ndikuwongolera phindu lazachuma.

4. Malo ochezeka komanso kuipitsa - kwaulere: Chovala cha ore chosawononga chilengedwe sichikhala chapoizoni komanso chosavulaza, chochezeka ndi chilengedwe, chimakwaniritsa zofunikira za chilengedwe, ndikuchepetsa kuwononga 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.
