I-Flotation Theory ye-Gold Ore

I-Flotation Theory ye-Gold Ore

Igolide livame ukukhiqizwa esimweni esikhululekile kuma-ores.Amaminerali avame kakhulu igolide lemvelo kanye nezinsimbi zegolide zesiliva.Wonke anokuntanta okuhle, ngakho ukuntanta kungenye yezindlela ezibalulekile zokucubungula amatshe egolide.Igolide livame ukuhlanganiswa namaminerali amaningi e-sulfide.I-Symbiotic, ikakhulukazi i-symbiotic ne-pyrite, ngakho-ke ukuntanta kwegolide nokuntanta kwezinsimbi ze-sulfide zensimbi njenge-pyrite enegolide kuhlobene eduze ekusebenzeni.Izinqubo zokuntanta zama-concentrator amaningana esizozethula ngezansi ngokuvamile amatshe egolide okuhlala kuwo igolide ne-sulfide minerals.

Ngokuya ngohlobo kanye nenani lama-sulfide, izinketho zokwelashwa ezilandelayo zingakhethwa.
① Uma i-sulfide ku-ore ngokuyinhloko iyi-pyrite, futhi ingekho enye i-sulfide yensimbi esindayo, futhi igolide ikakhulukazi liyizinhlayiya ezimaphakathi nezicolekileyo kanye ne-symbiotic ne-iron sulfide.I-ore enjalo iyantanta ukuze kukhiqizwe igolide le-sulfide, bese kuthi i-flotation igxiliswe i-atmosphere leaching, ngaleyo ndlela kugwenywe ukwelashwa kwe-cyanidation yayo yonke insimbi.I-flotation concentrate ingathunyelwa esitshalweni se-pyrometallurgy ukuze sicutshungulwe.Lapho igolide ikakhulukazi liwuhlobo lwezinhlayiya ezincane ezincane kanye ne-pyrite, umphumela oqondile we-cyanide leaching we-concentrate awumuhle, futhi kufanele iroswe ukuze kuhlukaniswe izinhlayiya zegolide bese lihushulwa umkhathi.

② Uma ama-sulfide ensimbi equkethe inani elincane le-chalcopyrite, i-sphalerite, ne-galena ngaphezu kwe-iron sulfide, igolide lihambisana nakho kokubili i-pyrite kanye nalawa ma-sulfide ensimbi esindayo.Uhlelo olujwayelekile lokwelapha: Ngokwenqubo evamile kanye nesistimu yamakhemikhali ye-non-ferrous metal sulfide ore, bamba bese ukhetha ukugxilisa okuhambisanayo.I-concentrate ithunyelwa ku-smelter ukuze icutshungulwe.Igolide lifaka ithusi noma umthofu (imvamisa ukugxilwa kwethusi eliningi) ligxile futhi litholwa ngesikhathi sokuncibilikiswa.Ingxenye lapho igolide ne-iron sulfide kuhambisana khona ingantanta ukuze kutholakale i-iron sulfide concentrate, engase itholakale ngokugazinga kanye nokucwiliswa komkhathi.

③ Uma kukhona ama-sulfide ayingozi emkhathini ku-ore, njenge-arsenic, i-antimony, nama-sulfide e-sulfide, i-sulfide concentrate etholwe ngokuntanta kufanele yosiwe ukuze kushiswe i-arsenic, i-sulfide nezinye izinsimbi ekugxiliseni zibe kalula Ukuze uthole ama-oxide ensimbi aguquguqukayo. , gaya i-slag futhi futhi usebenzise ipeni ukuze ususe ama-oxide ensimbi aguquguqukayo.

④ Uma ingxenye yegolide ku-ore ikhona endaweni ekhululekile, ingxenye yegolide ihambisana ne-sulfide, futhi ingxenye yezinhlayiya zegolide ifakwa kumaminerali e-ganggue.Insimbi enjalo kufanele ibuyiswe ngokuhlukaniswa kwamandla adonsela phansi ukuze kubuyiselwe igolide lamahhala, futhi kubuyiselwe i-symbiosis ne-sulfide ngokusebenzisa i-flotation Ukuze uthole igolide, kuye ngokuthi igolide linenani le-flotation tailings, kuyadingeka ukuthi kubhekwe ukuthi kufanele kusetshenziswe i-chemical leaching.I-flotation concentrate ingagaywa kahle bese icwiliswa ngqo, noma izinsalela ezishile zingagaywa kahle ngemva kokushiswa bese ziyacwiliswa.
