Chepetsani kutaya kwa mankhwala a sodium cyanide solution - Tetezani maziko

Mayankho a sodium cyanide amagwira ntchito yofunika kwambiri pakufukula zitsulo zamtengo wapatali, makamaka m'migodi ya golide. Popeza amagwiritsidwa ntchito kwambiri, kusunga bata la mayankhowa kumakhala kofunikira kwambiri. Komabe, kusinthasintha kwa mankhwala a sodium cyanide kumapangitsa kuti ikhale ndi zotayika zambiri popanda chitetezo choyenera.

Udindo Wosiyanasiyana wa Chitetezo cha Alkali

Kusunga Umphumphu Wothetsera Mavuto

Kuwonjezera kuchuluka koyenera kwa alkali—kotchedwa alkali yoteteza —kumathetsa vuto la kusakhazikika. Kumagwira ntchito ngati chothandizira chokhazikika, kuchepetsa kutayika kwa mankhwala a Sodium cyanide.

Neutralizing Reactive Compounds

Alkali yotetezayi imaletsanso mpweya wa carbon dioxide mu yankho. Kuphatikiza apo, imalimbana ndi ma asidi omwe amapangidwa ndi okosijeni wa mchere wa sulfide, ndikusunga malo abwino okhala ndi mankhwala.

Zoopsa za Kuchulukitsitsa kwa Alkalinity

Ngakhale kufunikira kwake, kuchuluka kwambiri kwa alkalinity kumatha kulepheretsa kutulutsa. Choyamba, zimachepetsa mlingo umene golide amasungunuka mu cyanide solution. Kuphatikiza apo, zimapangitsa kuti zinki zichuluke panthawi yosamukira, zomwe ndizofunikira pakubwezeretsa golide.

Laimu: Alkali Wotetezedwa Wokondedwa

Mtengo - Kuwongolera Mwachangu kwa Alkalinity

Laimu ndi chisankho chodziwika bwino pakusunga alkalinity yofunikira chifukwa cha mtengo wake - wogwira mtima. Imagwira bwino ntchito za alkali zoteteza.

Ubwino wa Flocculation

Kupitilira muyeso wa alkalinity, laimu amathandizira pakuyandama kwa mchere wopangidwa bwino ndi ma slimes mu zamkati. Izi zimathandizira kulekanitsa ndi kukonza mchere, kupititsa patsogolo kugwira ntchito bwino.

Mulingo woyenera Parameter Control mu Industrial Settings

pH ndi Calcium Oxide Concentration

Mu mafakitale opanga, kusunga pH ya yankho pakati pa 11 ndi 12 ndikofunikira kwambiri. Izi zimachitika poyang'anira mosamala kuchuluka kwa calcium oxide (CaO) yaulere kufika pa magawo 1 - 3 pa 10,000. Kuwongolera molondola magawo awa ndikofunikira kwambiri kuti njira yopangira cyanidation igwire bwino ntchito . Kumawonjezera kubwezeretsa kwa zitsulo zamtengo wapatali pomwe kumachepetsa kutayika kwa mankhwala komanso ndalama zopangira.
