Kugwiritsa Ntchito Polyacrylamide mu Golide ndi Siliva Ore Extraction

Kutulutsa bwino golide ndi siliva kuchokera ku miyala yamtengo wapatali ndi njira yovuta yomwe imafuna kulamulira bwino mankhwala ndi njira zamakono zopangira zinthu. Pakati pa zinthu zambiri zomwe zimagwiritsidwa ntchito mu migodi yamakono,Polyacrylamide(PAM) imadziwika kuti ndi imodzi mwa mankhwala ogwira mtima kwambiri komanso ogwiritsidwa ntchito kwambiri m'migodi. Ndi mphamvu zabwino zoyeretsera nthaka komanso kusinthasintha kwa mitundu yosiyanasiyana ya miyala, PAM imagwira ntchito yofunika kwambiri pakukweza kulekanitsa, kuwonjezera zokolola, komanso kuchepetsa kuwonongeka kwa chilengedwe panthawi yonse yobwezeretsa golide ndi siliva.

Momwe Polyacrylamide Imagwirira Ntchito Pochotsa Madzi

1. Kukonzekera kwa miyala

Njirayi imayamba ndi kuphwanya ndi kupukuta miyala, pomwe miyala yosaphika imachepetsedwa kukhala tinthu tating'onoting'ono toyenera kuchotsedwa. Mchere wophwanyikawu umasakanizidwa ndi madzi ndi laimu kuti upange matope ofanana mu mphero. Madzi otulukawo amapereka maziko a ntchito zachitsulo monga kukhetsa, kuchotsa, ndi kulowetsa.

2. Kutulutsa dothi ndi kusungunuka kwa madzi

Kenako matopewo amalowetsedwa mu chokhuthala cha pre-leach. Apa ndi pomweMa Flocculants a PolyacrylamideChoyamba amawonjezedwa. Mamolekyu a PAM amathandiza kumangirira tinthu tating'onoting'ono tolimba pamodzi, zomwe zimapangitsa kuti tipange magulu akuluakulu kapena "ma floc." Ma floc amenewa amakhazikika mofulumira pansi pa thanki yokhuthala, zomwe zimapangitsa kuti pamwamba pakhale gawo lamadzimadzi lokonzedwa bwino. Gawoli ndi lofunika kwambiri pochotsa zinthu zolimba zochulukirapo ndikuwonjezera mphamvu ya njira zamankhwala zotsatira.

3. Kuchotsa Cyanide

Pambuyo polekanitsa madzi olimba ndi olimba, matope okhuthala amalowa m'matanki angapo otulutsa madzi. M'matanki awa, yankho la cyanide limawonjezedwa kuti lisungunuke golide ndi siliva kuchokera mumkuwa. PAM imathandiza kusunga kusinthasintha kwa matope abwino komanso kukonza mgwirizano pakati pa cyanide ndi tinthu ta mchere. Kulumikizana kumeneku kumawonjezera mphamvu yotulutsa madzi, zomwe zimathandiza kuti golide ndi siliva wambiri apezekenso kuchokera ku kuchuluka komweko kwa miyala yaiwisi.

4. Kutengera Mpweya wa Kaboni

Zitsulo zamtengo wapatali zikasungunuka mu yankho, matope amalowa m'matanki osungira kaboni. Pa gawo ili, kaboni woyatsidwa umayamwa golide ndi siliva wosungunuka kuchokera mu yankho. Kugwiritsa ntchito polyacrylamide kumaonetsetsa kuti matopewo amayenda mofanana komanso osatsekeka, zomwe zimapangitsa kuti kusakaniza bwino komanso kuti madziwo azitha kulowa bwino. Kulumikizana kumeneku kukakhala kogwira mtima, kuchuluka kwa zitsulo zamtengo wapatali kumawonjezeka.

5. Kukonza ndi Kubwezeretsa Zitsulo

Mpweya wodzaza ndi chitsulo umalekanitsidwa ndikusamutsidwira ku dongosolo loyeretsera, komwe madzi otentha kwambiri kapena yankho la caustic cyanide limachotsa golide ndi siliva kuchokera ku kaboni. Yankho lobwezedwa, lomwe tsopano lili ndi ma ayoni achitsulo, limatumizidwa ku malo oyeretsera kuti liwonjezedwenso. Dothi lotsalalo—lomwe nthawi zambiri limatchedwa tailings—limasamutsidwira ku maiwe a tailings. Pano, PAM imagwiritsidwanso ntchito kukhazikika zinthu zotsala, kuyeretsa madzi, ndikuthandizira kusungidwa bwino kwa zinyalala za migodi.

Ubwino Wogwiritsa Ntchito Polyacrylamide Pokumba Golide

✅ Kutulutsa Kochuluka

Malinga ndi kafukufuku wokhudza kukonza njira zogwirira ntchito m'migodi, zinthu zopangidwa ndi polyacrylamide flocculants zimatha kuwonjezera kuchuluka kwa golide ndi siliva ndi zoposa 20%. Kuchuluka kwa njira zolekanitsira zinthu kumapangitsa kuti zitsulo zituluke bwino komanso kuti zinthu zopangidwa ndi miyala zigwiritsidwe ntchito bwino.

✅ Nthawi Yokonza Mofulumira

Mwa kufulumizitsa kusungunuka kwa madzi ndikuwongolera kuyenda kwa madzi oundana, PAM imathandiza kuchepetsa nthawi yosungira madzi m'matangi ndi m'mafakitale. Izi zingayambitse kukonza mofulumira ndi 30%, kukonza mphamvu yogwiritsira ntchito madzi komanso kuchepetsa nthawi yogwira ntchito.

✅ Yotsika Mtengo Komanso Yokhazikika

Kugwiritsa ntchito polyacrylamide kumathandiza kuchepetsa kuchuluka kwa cyanide ndi zinthu zina zofunika, zomwe zimathandiza kuchepetsa ndalama zogwiritsira ntchito mankhwala. Kuphatikiza apo, kubwezeretsanso madzi m'madzi komanso kuchepetsa kutulutsa mankhwala kumathandiza kuti migodi izigwira ntchito bwino, zomwe zimathandiza kuti ntchito zikwaniritse malamulo aboma komanso miyezo ya chilengedwe.

Wogulitsa Wodalirika wa Polyacrylamide pa Ntchito za Migodi

Monga katswiriwogulitsa mankhwala oyeretsera madzindi mankhwala opangidwa ndi migodi, timapereka mitundu yonse ya zinthu za polyacrylamide zoyenera kuchotsedwa mu golide ndi siliva. Kaya mukufuna anionic, cationic, kapena non-ionic PAM, timapereka:

• Kuyera kwambiri komanso khalidwe logwirizana
• Thandizo laukadaulo pakugwiritsa ntchito bwino mlingo ndi kugwiritsa ntchito
• Kulongedza mwamakonda ndi kutumiza zinthu zambiri
• Mitengo yampikisano komanso kutumiza mwachangu

Timagwiranso ntchito ma laboratories apamwamba komanso timayang'anira bwino kwambiri khalidwe kuti tiwonetsetse kuti gulu lililonse likukwaniritsa zofunikira zanu.
