Kugwiritsa ntchito Polyacrylamide mu Golide ndi Silver Ore Extraction

Kutulutsa bwino kwa golidi ndi siliva kuchokera ku ore ndi njira yovuta yomwe imafuna kuwongolera kolondola kwamankhwala ndi njira zotsogola. Mwa ma reagents ambiri omwe amagwiritsidwa ntchito mumigodi yamakono,Polyacrylamide(PAM) imadziwika kuti ndi imodzi mwamankhwala othandiza kwambiri komanso ogwiritsidwa ntchito kwambiri pamigodi. Ndi zinthu zabwino kwambiri zoyandama komanso kusinthika kwamitundu yosiyanasiyana ya ore, PAM imakhala ndi gawo lofunikira pakuwongolera kulekanitsa, kuchulukitsa zokolola, komanso kuchepetsa kukhudzidwa kwa chilengedwe munthawi yonseyi yobwezeretsa golide ndi siliva.

Momwe Polyacrylamide Imagwirira Ntchito Pochotsa

1. Kukonzekera Ole

Njirayi imayamba ndi kuphwanya miyala ndikupera, pomwe miyala yaiwisi imachepetsedwa kukhala tinthu tating'onoting'ono toyenera kutulutsa. Mwala wophwanyidwa uwu umasakanizidwa ndi madzi ndi laimu kuti apange slurry yunifolomu mu mphero ya mpira. Chifukwa cha slurry chimapereka maziko opangira zitsulo zotsika pansi monga sedimentation, leaching, ndi adsorption.

2. Sedimentation ndi Flocculation

Kenako slurry amalowetsedwa mu pre-leach thickener. Apa ndi pamenePolyacrylamide Flocculantsamawonjezedwa koyamba. Mamolekyu a PAM amathandizira kumanga tinthu tating'ono tolimba palimodzi, ndikupangitsa kuti tipange magulu akuluakulu kapena "mizere". Ziphuphuzi zimakhazikika mofulumira pansi pa thanki ya thickener, zomwe zimapangitsa kuti pakhale madzi omveka bwino pamwamba. Izi ndizofunikira pakuchotsa zolimba zochulukirapo ndikuwongolera magwiridwe antchito amankhwala omwe amatsatira.

3. Cyanide Leaching

Pambuyo pa kupatukana kolimba-kwamadzimadzi, slurry wokhuthala amalowa m'matangi angapo a leaching. M'matangi awa, njira ya cyanide imawonjezeredwa kuti asungunuke golide ndi siliva kuchokera ku miyala. PAM imathandizira kuti slurry isagwirizane bwino komanso imathandizira kuyanjana pakati pa cyanide ndi tinthu tambiri ta mchere. Kulumikizana kowonjezereka kumeneku kumapangitsa kuti golide ndi siliva wochulukirako zibwezedwe kuchokera ku miyala yaiwisi yomweyi.

4. Carbon Adsorption

Zitsulo zamtengo wapatalizo zikasungunuka mumtsuko, slurry amathamangira mu akasinja a carbon adsorption. Munthawi imeneyi, kaboni woyatsidwa umatsitsa golide ndi siliva wosungunuka kuchokera mu yankho. Kugwiritsiridwa ntchito kwa polyacrylamide kumatsimikizira kuti slurry imayenda mofanana komanso popanda kutseka, kulola kusakaniza bwino komanso kutsekemera kwambiri. Kulumikizana kumeneku kumapangitsa kuti zitsulo zamtengo wapatali zibwezeretsedwe.

5. Elution ndi Metal Recovery

Mpweya wodzaza zitsulo umasiyanitsidwa ndikusamutsidwa ku njira yowunikira, kumene madzi otentha kwambiri kapena caustic cyanide solution amachotsa golide ndi siliva ku carbon. Mankhwala ofufuzidwa, omwe tsopano ali ndi ayoni azitsulo, amatumizidwa kumalo osungunula kuti akayeretsedwenso. Dothi lotsalalo, lomwe nthawi zambiri limatchedwa tailings, limasamutsidwa ku maiwe otsekera. Apa, PAM imagwiritsidwanso ntchito kukhazikika zolimba zotsalira, kumveketsa bwino madzi, ndikuthandizira kusungidwa kotetezeka, kosamalira zachilengedwe kwa zinyalala zamigodi.

Ubwino Wogwiritsa Ntchito Polyacrylamide mu Migodi ya Golide

✅ Zokolola Zapamwamba Zazikulu

Polyacrylamide flocculants akhoza kuwonjezera golide ndi siliva kuchira mitengo ndi oposa 20%, malinga ndi migodi ndondomeko kukhathamiritsa maphunziro. Kuchita bwino kwa kulekanitsa kumabweretsa kutulutsa kwazitsulo zambiri komanso kugwiritsa ntchito bwino zinthu zachitsulo.

✅ Nthawi Yokonza Mwachangu

Mwa kufulumizitsa sedimentation ndikuwongolera kutuluka kwa slurry, PAM imathandizira kuchepetsa nthawi yosungira muzitsulo ndi akasinja. Izi zitha kubweretsa mpaka 30% kukonza mwachangu, kuwongolera kupitilira komanso kuchepetsa nthawi yogwira ntchito.

✅ Ndiwotsika mtengo komanso Wokhazikika

Kugwiritsa ntchito Polyacrylamide kumathandizira kuchepetsa kuchuluka kwa cyanide ndi ma reagents ena ofunikira, ndikuchepetsa mtengo wamankhwala. Kuonjezera apo, kukonzanso madzi obwezeretsanso komanso kuchepa kwa mankhwala kumathandizira kuti migodi ikhale yosasunthika, zomwe zimathandiza kuti ntchito zigwirizane ndi malamulo a boma ndi zachilengedwe.

Wodalirika Wopereka Polyacrylamide pa Ntchito Zamigodi

Monga katswiriwogulitsa mankhwala ochizira madzindi mankhwala migodi, timapereka uthunthu wonse wa mankhwala polyacrylamide oyenera golide ndi siliva miyala m'zigawo. Kaya mukufuna anionic, cationic, kapena non-ionic PAM, timapereka:

• Kuyera kwambiri komanso kusasinthasintha khalidwe
• Thandizo laukadaulo la mlingo ndi kukhathamiritsa kwa ntchito
• Kuyika mwamakonda ndi kutumiza zambiri
• Mitengo yampikisano komanso kutumiza mwachangu

Timagwiranso ntchito ma laboratories apamwamba ndikuwongolera mosamalitsa kuti gulu lililonse likwaniritse zomwe mukufuna kukonza.
