Zida Zopindulitsa za Gold Ore - Kutsegula Mtengo Wobisika wa Ores Golide

M'dziko lovuta la migodi ya golide, ulendo wochokera ku miyala yaiwisi, yosadabwitsa kupita ku chitsulo chonyezimira, chamtengo wapatali umayendetsedwa ndi gawo limodzi lofunika kwambiri: kupindula.Golide ore beneficiation zidandiye maziko aukadaulo panjira imeneyi, yopangidwa kuti isiyanitse golide ndi miyala yake yamtengo wapatali, kukulitsa mitengo yobwezeretsa, komanso kuchepetsa kuwonongeka kwa chilengedwe. Makina awa samangokhudza kuchotsa; ndi za kugwiritsa ntchito zinthu mwanzeru.

Beneficiation ndondomeko imayamba ndi kuphwanya ndi akupera. Zophwanyira zibwano, zophwanya ma cone, ndi mphero za mpira zimagwira ntchito limodzi kuti zichepetse zitsulo zazikuluzikulu kukhala ufa wosalala, kumasula tinthu tagolide kuti tisiyanitse. Mtima wopindula, komabe, uli mu njira zolekanitsa. Apa, zida ngati ma centrifugal concentrators, monga ma Knelson ndi Falcon concentrators, amagwiritsa ntchito mphamvu yokoka kwambiri kuti apezenso tinthu tating'ono tagolide. Makina a jig amalekanitsa zida kutengera kusiyanasiyana kwa kachulukidwe, kupanga madzi othamanga omwe amalumikizana ndi miyala, zomwe zimapangitsa golide wolemera kukhazikika.

Kwa ores komwe golide amalumikizana ndi mchere wina, makina oyandama amalowa. Amayambitsa mankhwala omwe amapanga mchere wokhala ndi golidi kukhala hydrophobic, kuwapangitsa kumamatira ku thovu la mpweya ndikuyandama pamwamba kuti atolere. Pakali pano, matebulo ogwedezeka amagwiritsa ntchito kugwedezeka kokonzedwa bwino ndi kutuluka kwa madzi kuti alekanitse tinthu tating'ono ndi kachulukidwe ndi kukula, kumapanga mtsinje wa golide wokhazikika.

Kupindula kwamakono kumaposa kulekana chabe. Makina a Carbon-in-Leach (CIL) ndi Carbon-in-Pulp (CIP) amayimira matekinoloje apamwamba adsorption, pomwe mpweya wopangidwa ndi kaboni umagwira golide wosungunuka kuchokera ku zamkati za cyanide-leached. Machitidwewa amathandizidwa ndi zida zopangira ma electrowinning ndi smelting, zomwe zimamaliza ntchitoyi pochotsa golide woyenga kuchokera ku carbon yodzaza.

Mtengo weniweni wamakonozida zothandizira golidet zagona mu kuphatikiza kwake ndi luntha. Makina odziwongolera okha amakwaniritsa gawo lililonse - kuyambira kuchuluka kwa chakudya ndi kuchuluka kwa madzi mpaka mlingo wamankhwala - kuwonetsetsa kuti zikuyenda bwino kwambiri, kuchepetsa kugwiritsa ntchito mphamvu, komanso kutsika mtengo. M'nthawi ya ore yomwe ikuchulukirachulukira komanso malamulo okhwima azachilengedwe, zida izi zikusintha kuti zithetse njira zobiriwira, monga mabwalo amadzi otsekedwa ndi njira zina, zopanda poizoni.

Pamapeto pake, zida zopezera golide ndiye chinsinsi chosinthira ma depositi am'mphepete kukhala mabizinesi opindulitsa ndikukulitsa moyo wamigodi yomwe ilipo. Ndi ngwazi yosadziwika yomwe imatsimikizira kuti lonjezo la golide padziko lapansi silimangopezeka, koma limakwaniritsidwa mokwanira komanso moyenera.
