Gukoresha Polyacrylamide mu gukuramo zahabu na feza

Gucukura zahabu na feza mu mabuye y'agaciro neza ni inzira igoye isaba kugenzura neza imiti n'ubuhanga buhanitse bwo kuyitunganya. Mu bintu byinshi bikoreshwa mu bucukuzi bwa none,Polyacrylamide(PAM) igaragara nk'imwe mu miti icukura neza kandi ikoreshwa cyane mu bucukuzi bw'amabuye y'agaciro. Ifite ubushobozi bwiza bwo gukurura no guhuza n'ibice bitandukanye by'amabuye y'agaciro, PAM igira uruhare runini mu kunoza itandukana ry'amabuye y'agaciro, kongera umusaruro, no kugabanya ingaruka ku bidukikije mu gihe cyose cyo kugarura zahabu na feza.

Uburyo Polyacrylamide Ikora mu Gukuramo Ibinyabutabire

1. Gutegura amabuye y'agaciro

Iyi gahunda itangirana no gusya no gusya amabuye, aho amabuye mashya agabanywa akagera ku ngano ntoya ikwiriye gukurwamo. Hanyuma ayo mabuye ashwanyagujwe avanganywa n'amazi n'indimu kugira ngo habeho urusenda rumwe mu ruganda rukora umupira. Urusenda ruvuyemo rutanga urufatiro rw'ibikorwa by'icyuma byo mu mazi nko gusya, gusohora no gukurura.

2. Gutera imirasire no gukurura amazi mu mazi

Hanyuma, urusenda rushyirwa mu cyuma gifasha gukurura amazi. Aha nihoPolyacrylamide FlocculantsYongerwaho bwa mbere. Molekile za PAM zifasha guhuza uduce duto tw’ibice bikomeye, bigatuma dukora uduce duto cyangwa “uduce duto.” Utwo duce duto twinjira vuba hasi mu gikoresho cyo gukurura, bigatuma habaho igice cy’amazi gisobanutse neza hejuru. Iyi ntambwe ni ingenzi mu gukuraho ibintu bikomeye no kunoza imikorere y’ibinyabutabire bikurikiraho.

3. Gusukura Cyanide

Nyuma yo gutandukanya amazi akomeye n'amazi, urusenda rwagutse rwinjira mu bigega byinshi bikuramo amazi. Muri ibyo bigega, hongerwamo umuti wa cyanide kugira ngo ushongeshe zahabu na feza biri mu mabuye y'agaciro. PAM ifasha kubungabunga imiterere myiza y'urusenda kandi ikanoza imikoranire hagati ya cyanide n'utubumbe tw'amabuye y'agaciro. Uku kongera ubushobozi bwo gukorana byongera ubushobozi bwo gukuramo amazi, bigatuma zahabu na feza byinshi bigaruzwa mu bunini bumwe bw'amabuye y'agaciro.

4. Gukoresha karuboni mu gukurura

Iyo ibyuma by'agaciro bimaze gushonga mu gikoresho, igitereko cyinjira mu bigega byo gushonga karubone. Muri iki cyiciro, karubone ikora ifata zahabu na feza byashongeshejwe mu gikoresho. Gukoresha polyacrylamide bituma igitereko kigenda neza kandi kidafunganye, bigatuma bivanga neza kandi bigahita bishonga cyane. Uko ibi bikorwa neza, niko ibyuma by'agaciro bihita byiyongera.

5. Gusubiza no Gusubiza Ibyuma mu buryo bwa Elution

Hanyuma karubone yuzuye icyuma iratandukana ikajyanwa muri sisitemu yo gucukura, aho amazi ashyushye cyane cyangwa umuti wa cyanide ukuraho zahabu na feza muri karubone. Umuti wabonetse, ubu ukungahaye kuri iyoni z'icyuma, woherezwa mu ruganda rutunganya ubutare kugira ngo wongere utunganywe. Uduce dusigaye tw'amazi—bizwi nka tailings—twimurirwa mu bidendezi by'amazi. Aha, PAM yongera gukoreshwa mu gutuza ibisigazwa by'amazi, gutunganya amazi, no gushyigikira kubika imyanda y'amabuye y'agaciro mu buryo bwizewe kandi butangiza ibidukikije.

Ibyiza byo gukoresha Polyacrylamide mu gucukura zahabu

✅ Umusaruro mwinshi wo gucukura

Inyigo zo kunoza uburyo bwo gucukura amabuye y'agaciro zigaragaza ko imiti ya polyacrylamide ishobora kongera igipimo cyo kugarura zahabu na feza ku kigero kirenga 20%. Uko gutandukanya amabuye y'agaciro birushaho kuba byiza bituma habaho umusaruro mwinshi w'ibyuma no gukoresha neza umutungo kamere w'amabuye y'agaciro.

✅ Igihe cyo gutunganya vuba

Mu kwihutisha uburyo amazi akoreshwa mu gusya no kunoza uburyo amazi anyuramo, PAM ifasha kugabanya igihe cyo kubika amazi mu byuma binini n'ibigega. Ibi bishobora gutuma habaho kwihuta kugeza kuri 30% mu gutunganya, kunoza uburyo amazi akoreshwa no kugabanya igihe cyo kudakora neza.

✅ Ihendutse kandi irambye

Gukoresha polyacrylamide bifasha kugabanya ingano ya cyanide n'ibindi binyabutabire bikenewe, bigabanura ikiguzi cy'imiti. Byongeye kandi, kunoza uburyo bwo kongera gukoresha amazi no kugabanya ikoreshwa ry'imiti mu bucukuzi bw'amabuye y'agaciro bigira uruhare mu bucukuzi bw'amabuye y'agaciro burambye, bigafasha ibikorwa kubahiriza amabwiriza ya leta n'amahame agenga ibidukikije.

Umutanga serivisi wizewe wa Polyacrylamide mu gucukura amabuye y'agaciro

Nk'umunyamwugautanga imiti ikoreshwa mu gutunganya amazin'imiti ikoreshwa mu bucukuzi bw'amabuye y'agaciro, dutanga ubwoko bwose bw'ibicuruzwa bya polyacrylamide bikwiriye gucukurwamo zahabu na feza. Waba ukeneye anionic, cationic, cyangwa non-ionic PAM, dutanga:

• Isuku cyane kandi ifite ubuziranenge buhoraho
• Ubufasha mu bya tekiniki mu gupima no kunoza ikoreshwa ry'ibipimo
• Gupakira byihariye no gutanga ibicuruzwa byinshi
• Ibiciro bihiganwa no kohereza byihuse

Dukora kandi laboratwari zigezweho kandi dukomeza kugenzura neza ubuziranenge kugira ngo buri cyiciro cyujuje ibisabwa mu gutunganya.
