Kuwunika ndi Kuwongolera kwa Sodium Cyanide Concentration mu Gold Production

Introduction

Mu makampani opanga migodi ndi kuchotsa golide, kugwiritsa ntchito Sodium cyanide mu njira yochotsera golide ndi njira yodziwika bwino yochotsera golide kuchokera ku miyala. Kuchuluka kwa Sodium Cyanide mu njira yochotsera golide kumachita gawo lofunika kwambiri pakugwira bwino ntchito komanso kugwira ntchito bwino kwa kuchotsa golide . Kuyang'anira bwino ndi kuwongolera kuchuluka kwa golide kumeneku ndikofunikira kuti golide abwererenso bwino, kuchepetsa kuwonongeka kwa chilengedwe, komanso kusunga ndalama zomwe zikugwira ntchito.

Kufunika kwa Sodium Cyanide Concentration mu Gold Production

Gold Dissolution Kinetics

Kusungunuka kwa golide mu yankho la cyanide kumatsatira njira yovuta ya mankhwala. Kuchuluka kokwanira kwa sodium cyanide ndikofunikira kuti kuyendetse patsogolo njirayo. Kuchuluka kochepa kwa cyanide kungayambitse kusungunuka kwa golide pang'onopang'ono, zomwe zimapangitsa kuti golide asatuluke mokwanira komanso kuchepetsa kuchuluka kwa golide. Kumbali ina, kuchuluka kwambiri kungayambitse kugwiritsa ntchito mankhwala osafunikira, ndalama zambiri, komanso zoopsa zomwe zingachitike pa chilengedwe.

Makhalidwe a Ore

Mitundu yosiyanasiyana ya ores imakhala ndi mayankho osiyanasiyana ku cyanide. Ores okhala ndi sulfide wambiri kapena mineralogy yovuta angafunike kuchuluka kwa cyanide kuti achotse golide moyenera. Kuyang'anira ndende ya cyanide kumathandizira ogwiritsa ntchito kusintha njirayo malinga ndi mawonekedwe a ore omwe akukonzedwa, kukulitsa kuchira kwa golide ndikuchepetsa zinyalala za mankhwala.

Njira Zowunika Kuyika kwa Sodium Cyanide

Titration

Titration ndi njira yachikhalidwe komanso yogwiritsidwa ntchito kwambiri poyezera kuchuluka kwa cyanide. Mwanjira iyi, njira yokhazikika ya silver nitrate imawonjezeredwa ku chitsanzo chomwe chili ndi cyanide. Ma ions a siliva amachitira ndi ma cyanide ions kupanga siliva cyanide complex. Mapeto a titration amatsimikiziridwa pogwiritsa ntchito chizindikiro, ndipo ndende ya cyanide imatha kuwerengedwa kutengera kuchuluka kwa nitrate yasiliva yomwe imagwiritsidwa ntchito. Ngakhale kuti ndizosavuta komanso zotsika mtengo, zolemba za zilembo zimakhala ndi malire, monga kuwononga nthawi komanso kumafuna odziwa ntchito kuti atsimikizire zotsatira zolondola.

Ion - Ma Electrodes Osankha

Ma Ion - selective electrode (ISE) amapereka njira yowunikira mwachangu komanso mosalekeza. Elekitirodi yosankha ya cyanide imamizidwa mu yankho, ndipo kusiyana komwe kungachitike kumapangidwa potengera ntchito ya cyanide ion mu yankho. Kuthekera kumeneku kumayesedwa ndikulumikizidwa ndi ndende ya cyanide. Ma ISE amapereka zenizeni zenizeni zenizeni, kulola kusintha mwachangu pakuwonjezera kwa cyanide munjirayo. Komabe, angafunike kuwongolera pafupipafupi ndipo amatha kukhudzidwa ndi kusokoneza zinthu mu yankho.

Zojambulajambula

Njira za Spectrophotometric zimadalira kuyamwa kwa kuwala ndi cyanide - zokhudzana ndi mankhwala. Mwachitsanzo, ma reagents ena amachitira ndi cyanide kupanga mitundu yamitundu, ndipo kuyamwa kwa ma complexes pa utali wosiyanasiyana kumayesedwa. Kuchuluka kwa cyanide kungadziwike kuchokera pamapindikira a calibration. Spectrophotometry imapereka chidwi chachikulu komanso kulondola, koma nthawi zambiri imafunikira kukonzekera ndi zida zovuta kwambiri.

Njira Zowongolera za Sodium Cyanide Concentration

Makinawa Dosing Systems

Makina opangira madontho pawokha akukhala otchuka kwambiri muzomera zamakono zagolide. Machitidwewa ali ndi masensa omwe amawunika mosalekeza kuchuluka kwa cyanide mu njira ya leaching. Kutengera ndende yoyezera komanso milingo yomwe yakhazikitsidwa kale, dongosolo la dosing limangosintha kuchuluka kwa sodium cyanide yomwe yawonjezeredwa panjirayo. Izi zimawonetsetsa kuti ndende ya cyanide imakhalabe munjira yoyenera, kuchepetsa zolakwika za anthu ndikuwongolera kukhazikika kwadongosolo.

Kukhathamiritsa kwa Njira Kutengera zenizeni - Zanthawi Yanthawi

Kubwera kwaukadaulo wapamwamba wowongolera njira, opanga golide tsopano atha kuphatikizira zenizeni zenizeni zanthawi ya cyanide ndi magawo ena azinthu monga pH, kutentha, ndi liwiro la chipwirikiti. Mwa kusanthula deta iyi palimodzi, ogwira ntchito amatha kuzindikira maulalo ndikuwongolera njira yonse ya cyanidation. Mwachitsanzo, kusintha pH ya yankho kungakhudze kutchulidwa kwa cyanide ndi reactivity yake ndi golidi, ndipo kuwongolera kogwirizana kwa magawowa kungayambitse kutulutsa golide koyenera.

Kuganizira Zachilengedwe ndi Chitetezo

Sodium cyanide ndi mankhwala oopsa kwambiri, ndipo malamulo okhwima okhudza chilengedwe ndi chitetezo amalamulira kugwiritsidwa ntchito kwake mumakampani opanga golide. Kuyang'anira bwino ndi kuwongolera kuchuluka kwa cyanide sikuti kumangowonjezera magwiridwe antchito a golide komanso kumathandiza kuchepetsa kutayikira kwa cyanide komanso kuipitsa chilengedwe. Kuphatikiza apo, kusamalira bwino ndi kusungira sodium cyanide, komanso mapulani othandizira pakagwa ngozi, ndi zinthu zofunika kwambiri pa kayendetsedwe ka chitetezo m'migodi yagolide.

Kutsiliza

Kuwunika ndi kuwongolera kuchuluka kwa sodium cyanide pakupanga golide ndizofunikira kwambiri pakuchita bwino kwa cyanidation. Pogwiritsa ntchito njira zapamwamba zowunikira komanso njira zowongolera bwino, opanga golide amatha kupeza mitengo yapamwamba yobwezeretsa golide, kutsika mtengo wopangira, komanso kuwongolera chilengedwe. Pamene ntchito ya migodi ya golide ikupitirizabe kusintha, kufufuza kwina ndi chitukuko m'derali mosakayikira kudzatsogolera ku njira zogwirira ntchito zopezera golide.
