Zida zopezera golide ndi chiyani?

Momwe mungatulutsire golide ku matabwa ozungulira?

Integrated zida m'zigawo golide: lalikulu electroplating wathunthu zida / golide ndi siliva electrolysis kuchira makina, mpweya kabati, madzi kuthira makina, galasi anachita ketulo, aqua regia kusefera galimoto, Ph basi dosing dongosolo, kuchepetsa ndi kusefera Integrated makina, siponji golide kusefera mbiya, PP kuchepetsa anachita thanki, neutralization thanki, awiri wosanjikiza ketulo anachita golide wosungunula zipangizo, anali etc.

Mtengo wake wa zida zoyengera golide zama board ozungulira ndi waukulu kwambiri, kuyambira makumi masauzande mpaka masauzande. Mtengo umakhudzidwa ndi zinthu monga kukula kwachitsanzo cha zida, zinthu zopangira, mtundu, kapangidwe kake, ndi kukula kwake, ndipo zimatha kusinthasintha m'mwamba ndi pansi. Ndizovuta kudziwa mtengo wokhazikika, ndipo opanga atha kungopereka mawu enieni atatha kudziwa zomwe mukufuna komanso momwe mumagwirira ntchito.

Zida zoyenga zazitsulo zamtengo wapatali zimagwiritsidwa ntchito makamaka pochotsa zitsulo zamtengo wapatali monga golidi, siliva, platinamu, palladium, ndi zina zotero. Panopa, Fuxin Environmental Refining makamaka imagwiritsa ntchito njira monga kuyeretsa chlorine, kuyeretsa aqua regia, electrolysis kuyeretsa, kuyeretsa chloramine, ndi zina zotero.

Zida zomwe zimagwiritsidwa ntchito nthawi zambiri zikuphatikizapo: makina akuluakulu a electroplating athunthu / golide ndi siliva electrolysis kuchira makina, mpweya mpweya, madzi splash makina, galasi reaction ketulo, aqua regia fyuluta galimoto, Ph basi dosing dongosolo, kuchepetsa ndi kusefera Integrated makina, siponji golide fyuluta mbiya, PP kuchepetsa reaction thanki, neutralization thanki, awiri wosanjikiza ketulo anachita kusungunula golide, ndi zinyalala zipangizo mankhwala.

Kodi njira zochotsera zitsulo zamtengo wapatali ku golidi ndi ziti?

Golide ndi chinthu chachilengedwe chomwe sichingapangidwe mwaluso, ndipo chimagawidwa kukhala golide wakuda ndi golide wophika. Golide yemwe wafika pachiyero chambiri atayeretsedwa amatchedwa golide woyenga bwino, nthawi zambiri amatanthauza golide wokhala ndi mafinya opitilira 99.6%. Golide woyeretsedwa nthawi zambiri amakhala wachiyero kwambiri, ndipo ena amatha kugwiritsidwa ntchito mwachindunji kupanga mafakitale.

1. Mmene Mungayeretsere Golide

Single flotation ndi oyenera pokonza coarse ndi sing'anga grained zachilengedwe golide chitsulo ore. Mwala wophwanyidwawo umadyetsedwa mu mphero ya mpira, ndikuugwetsa mu slurry, ndiyeno kulowa pansi. Kuyandama kosanganikirana kwa mercury ndikoyenera kukonza golide wachilengedwe wokhala ndi tinthu tating'ono tomwe timasungidwa, kusungidwa mu pyrite ndi miyala ina ya sulfide. Mosiyana ndi kuyandama kumodzi, kuwonjezera mbale ya mercury pambuyo pogaya kuti golide abwezeretsedwe amatha kuchira 30-45%. Kutumiza kwa lamba mu bwalo la tailings; Mchenga wa ore womwe suli wokulirapo kuposa dzenje la sieve umalowetsedwa mu makina ozungulira ozungulira a 1-3 kudzera mu chosakanizira chapagulu, ndipo nsongayo imalowa patebulo logwedezeka kudzera pamakina atatu opukutira pamakina owoneka bwino, abwino komanso osesa kuti apange miyala yabwino yamchenga. Njira imeneyi nthawi zambiri imagwiritsidwa ntchito popanga migodi yamchenga, ndipo miyala yabwino yophwanyidwa ingagwiritsidwenso ntchito.

2. Chiyambi cha Njira Yochotsera Golide mwa Kusakaniza Mercury ndi Kuyeretsa Golide

Iyi ndiyo njira yakale yoyeretsera golide, malinga ngati muli ndi chipiriro, mukhoza kutchula chiyero chapamwamba. Njira zenizeni ndi izi:

Madzi a golidi + mercury +, akugaya mosalekeza mpaka palibe tinthu tating’ono ta golide, ndipo golidi ndi mercury zimapanga mankhwala a intermetallic. Pogaya ndi kusakaniza ufa wa sulfure ndi golide wopangidwa ndi mercury, ndi kutentha ndi kuwotcha mu mpweya. Panthawiyi, mercury yotsalayo imasanduka nthunzi, ndipo zitsulo zapansi zimayamba kupanga sulfides zitsulo, zomwe pambuyo pake zimapanga zitsulo zazitsulo. Bwerezerani ntchitoyi kangapo ndikuwonjezera borax kuti isungunuke muzitsulo zagolide. Ma base metal oxides amakhudzidwa ndi borax kuti apange zinthu zochepa zosungunuka, zomwe zimayandama pamwamba pamadzimadzi. Golide woyenga adzagwiritsa ntchito njirayi pansi kuti ateteze ku poizoni wa mercury vapor.

3. Chiyambi cha Njira Yoyeretsera Golide Yonyowa pochotsa Golide

Njira yoyeretsera golide yonyowa imatenga njira yosungunulira golide mu aqua regia ndikuwonjezera chochepetsera kuchepetsa golide, kapena ngati masking agent amagwiritsidwa ntchito kuzinthu zovuta zosokoneza, ndikutsatiridwa ndi kuchotsedwa ndi wothandizira kapena chotsitsa choyambirira. Kupangaku kumadutsa munjira zakale monga kusungunuka kwa kutentha kwambiri ndi njira zina zosavuta zoyeretsera kuti mupeze golide wapamwamba kwambiri. Poyerekeza ndi matekinoloje omwe alipo kale, zomwe zidapangidwa pano zimakhala ndi chiyero chapamwamba chazinthu, kuchepetsa mtengo wopangira, komanso njira zosavuta komanso zothandiza. Njira ina ndi kuyeretsedwa konyowa kwa ndondomeko ya golide, yomwe imaphatikizapo kuyika golide wakuda mu chidebe, ndikuwonjezera ku aqua regia yomwe yangokonzedwa kumene kuti imirire golide wosakanizidwa, ndikuwotcha kuti isungunuke kwa mphindi 15-25. Ngati golidi wakuda sakusungunuka kwathunthu, aqua regia akhoza kuwonjezeredwa kuti asungunuke mobwerezabwereza mpaka atasungunuka kwathunthu.

Pomaliza, gwiritsani ntchito makina opangira zitsulo zamtengo wapatali a Hasung popanga mipiringidzo yagolide yonyezimira, ndi makina opangira matabwa. makina opangira golide makina osungunula induction , etc.
