Kuwunika ndi Kuwongolera kwa Sodium Cyanide Concentration mu Gold Production

Introduction

M'makampani a migodi ndi kutulutsa golide, kugwiritsa ntchito Sodium cyanide mu njira ya cyanidation ndi njira yodziwika bwino yopezera golide kuchokera ku miyala. Kukhazikika kwa Sodium Cyanide mu leaching solution imagwira ntchito yofunika kwambiri pakuchita bwino komanso kuchita bwino Kuchotsa golide. Kuyang'anira bwino ndikuwongolera ndendeyi ndikofunikira kuti golide abwezeretsedwe bwino, kuchepetsa kuwonongeka kwa chilengedwe, ndikusunga chuma chantchitoyo.

Kufunika kwa Sodium Cyanide Concentration mu Gold Production

Gold Dissolution Kinetics

Kusungunuka kwa golide mu a cyanide njira amatsatira zovuta mankhwala anachita. Zokwanira sodium cyanide ndende m'pofunika kuyendetsa anachita patsogolo. Kuchuluka kwa cyanide kungayambitse kusungunuka kwa golide pang'onopang'ono, zomwe zimabweretsa kuchotsedwa kosakwanira komanso kuchepa kwa zokolola za golide. Komano, kuchulukitsidwa mopitirira muyeso kungayambitse kumwa mankhwala osafunikira, kukwera mtengo, ndi kuopsa kwa 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 a chilengedwe ndi chitetezo amayendetsa ntchito yake pamakampani a golide. Kuwunika kolondola komanso kuwongolera ndende ya cyanide sikungowonjezera luso la Kupanga golide komanso kuthandiza kuchepetsa chiopsezo cha cyanide kutayikira ndi kuipitsa chilengedwe. Kuonjezera apo, kusamalira bwino ndi kusunga sodium cyanide, komanso ndondomeko zoyankhira mwadzidzidzi ngati zitatayika, ndizofunikira kwambiri pa kayendetsedwe ka chitetezo chokwanira m'migodi ya golide.

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.
