Chifukwa chiyani Sodium Cyanide Imagwiritsidwa Ntchito Kwambiri M'zigawo Zagolide?

Pankhani yochotsa golide , sodium cyanide imakhala ngati chothandizira chachikulu pamakampani. Koma n’chifukwa chiyani chimachipangitsa kukhala chofunikira kwambiri? Tiyeni tione zifukwa zomwe zimachigwiritsira ntchito kwambiri.

1. Chemical Reactivity

Kugwira ntchito kwa sodium cyanide pochotsa golide makamaka chifukwa cha mphamvu zake zapadera. Golide, monga momwe alili, ndi wosagwira ntchito ndipo sachita zinthu zambiri zodziwika bwino. Komabe, Sodium Cyanide ikalowetsedwa mu njira yochotsera, imachita zinthu ndi golide pamaso pa mpweya ndi madzi kuti ipange golide-cyanide wosungunuka. Kuchita izi kumasintha tinthu ta golide tosasungunuka kukhala sungunuka, zomwe zimapangitsa kuti pakhale kusiyana kosavuta kuchokera ku matrix ya ore. Kuthekera kopanga zinthu zokhazikika komanso zosungunuka ndi golide ndi chinthu chofunikira kwambiri pakugwiritsa ntchito kwambiri Sodium cyanide mumigodi ya golide.

2. Kuchita bwino ndi Ungwiro

Chimodzi mwa ubwino waukulu wogwiritsa ntchito sodium cyanide pochotsa golide ndi mphamvu yake yapamwamba. Kuchotsa cyanide kumatha kubweretsa golide wambiri, nthawi zambiri kumachotsa golide wokwana 90% kapena kuposerapo womwe uli mumkuwa, kutengera mawonekedwe a mkuwawo. Poyerekeza ndi njira zina zochotsera, monga kuphatikiza kwa MERCURY , kuchotsa cyanide kumakhala kothandiza kwambiri pochotsa golide kuchokera ku mitundu yosiyanasiyana ya mkuwa, kuphatikizapo miyala yotsika mtengo.

Kuphatikiza apo, golide-cyanide yomwe imapangidwa panthawi yolowera imatha kukonzedwanso kuti ipeze golide woyenga kwambiri. Kupyolera mu njira zotsatila monga mvula yokhala ndi zinki kapena electrolysis, golidiyo amatha kubwezeredwa m'malo abwino kwambiri, kukwaniritsa zofunikira zamtengo wapatali za zodzikongoletsera, zamagetsi, ndi misika yamalonda.

3. Mtengo - wogwira mtima

Kuchokera pazachuma, sodium cyanide imapereka mtengo - wogwira mtima. Ngakhale kuti sodium cyanide palokha ndi chinthu chapoizoni, mtengo wake wopanga ndi kugula ndi wololera poyerekeza ndi zopangira zina zomwe zingagwiritsidwe ntchito pochotsa golide. Kuonjezera apo, ndondomeko ya cyanidation yakhazikitsidwa bwino komanso yokonzedwa bwino kwa zaka zambiri. Zomangamanga ndi zida zomwe zimafunikira pakubowoleza kwa cyanide ndizokhazikika, zomwe zimachepetsa kufunikira kwaukadaulo wamtengo wapatali, wapadera. Izi zikutanthauza kuti makampani opanga migodi atha kupeza golide woyenga bwino pamtengo wotsika kwambiri pagawo lililonse la golide wopangidwa, zomwe zimapangitsa kuti ikhale njira yowoneka bwino m'makampani omwe akupikisana nawo kwambiri.

4. Zomangamanga Zokhazikitsidwa ndi Zodziwika

Makampani opanga migodi golide akhala akugwiritsa ntchito sodium cyanide pochotsa golide kwazaka zopitilira zana. Zotsatira zake, pali maziko opangidwa bwino ozungulira kugwiritsa ntchito sodium cyanide. Makampani amigodi ali ndi mwayi wopeza njira yodalirika ya sodium cyanide, kuchokera pakupanga kupita kumayendedwe ndi kusungirako.

Kuphatikiza apo, akatswiri opanga migodi, akatswiri, ndi ogwira ntchito amadziwa bwino za cyanidation. Amaphunzitsidwa kugwiritsa ntchito sodium cyanide mosamala, kugwiritsa ntchito zida za leaching, ndikuwongolera njira yonse yochotsa. Chidziwitso ndi ukadaulo wosonkhanitsidwawu umapangitsa kuti ntchito zamigodi zikhale zosavuta kugwiritsa ntchito ndikusunga njira ya cyanidation, kuchepetsa njira yophunzirira komanso zoopsa zomwe zingachitike potengera njira zatsopano komanso zosayesedwa.

5. Kusintha kwa Mitundu Yosiyanasiyana ya Miyala

Sodium cyanide - njira zopangira zotengera zimatha kusinthana ndi mitundu yosiyanasiyana ya golide. Kaya ndi yaulere - milling ores pomwe golide amamasulidwa mosavuta ku thanthwe lanyumba, kapena ma ore ovuta kwambiri omwe amafunikira masitepe owonjezera, cyanide leaching imatha kusinthidwa ndikuwongoleredwa. Kwa ore osakanizidwa, njira monga kukazinga, kutsekemera kwa okosijeni, kapena bio-oxidation imatha kuphatikizidwa ndi cyanide leaching kuti iwononge kapangidwe ka miyala ndikuwonetsa golide ku yankho la cyanide, zomwe zimapangitsa kuti azitha kutulutsa bwino. Kusinthasintha uku kumapangitsa kuti sodium cyanide ikhale chisankho chokondedwa kwa makampani amigodi omwe amagwira ntchito ndi ma depositi osiyanasiyana.

Komabe, ndikofunikira kudziwa kuti ngakhale sodium cyanide imapereka zabwino zambiri pakuchotsa golide, kugwiritsidwa ntchito kwake kumadzetsanso nkhawa kwambiri zachilengedwe ndi chitetezo chifukwa cha kawopsedwe wake wambiri. Zotsatira zake, makampaniwa akufufuza mosalekeza ndikupanga njira zina zochotsera ndikuwongolera njira zotetezera kuti achepetse zoopsa zomwe zimagwirizanitsidwa ndi kugwiritsa ntchito sodium cyanide ndikukwaniritsa kufunikira kwa golide padziko lonse lapansi.
