Flotation Theory yeGoridhe Ore

Flotation Theory yeGoridhe Ore

Ndarama inowanzogadzirwa mune yakasununguka mamiriro mune ores.Maminerari anonyanyozivikanwa igoridhe rechisikigo uye sirivha-goridhe ores.Vese vane zvakanaka kutenderera, saka flotation ndiyo imwe yenzira dzakakosha dzekugadzirisa ores dzegoridhe.Ndarama inowanzosanganiswa nemamineral akawanda e sulfide.Symbiotic, kunyanya inowanzo symbiotic nepyrite, saka kutenderera kwegoridhe uye kuyerera kwesimbi sulfide ores senge goridhe-inobereka pyrite zvine hukama padhuze mukuita.Maitiro ekuyangarara emaconcentrator akati wandei atichasuma pazasi anonyanya kuve ores egoridhe umo goridhe uye sulfide zvicherwa zvinogara pamwe chete.

Zvichienderana nerudzi uye huwandu hwe sulfides, nzira dzinotevera dzekurapa dzinogona kusarudzwa.
① Kana iyo sulfide mu ore ichinyanya pyrite, uye pasina imwe inorema simbi sulfides, uye goridhe rinonyanya riri pakati nepakati uye zvidimbu zvidimbu uye symbiotic ine iron sulfide.Maore akadaro anotenderedzwa kuti abudise sulfide goridhe concentrate, uye flotation concentrates inobva yanyudzwa neatmosphere leaching, nekudaro kudzivirira kurapwa kwecyanidation yeore yese.Iyo flotation concentrate inogona zvakare kutumirwa kune pyrometallurgy chirimwa kuti chigadziriswe.Kana iyo goridhe iri kunyanya muchimiro che submicroscopic particles uye pyrite, yakananga cyanide leaching maitiro eiyo concentrate haina kunaka, uye inofanirwa kugochwa kuti isiyanise zvimedu zvegoridhe uye yobva yanyudzwa nemhepo.

② Kana ma sulfide ari muore aine kachalcopyrite, sphalerite, uye galena kuwedzera kune iron sulfide, goridhe inowirirana nezvose zviri zviviri pyrite uye idzi heavy metal sulfides.General kurapwa chirongwa: Zvinoenderana neyakajairwa maitiro uye makemikari sisitimu yeasina-ferrous metal sulfide ore, tora uye sarudza inowirirana concentrate.Iyo concentrate inotumirwa kune smelter kuti igadziriswe.Ndarama inopinda mhangura kana mutobvu (kazhinji mhangura yakawanda) inonangana uye inodzoserwa panguva yekunyungudutswa.Iyo chikamu icho goridhe nesimbi sulfide zviri symbiotic inogona kutenderedzwa kuti iwane iron sulfide concentrate, iyo inogona kudzoserwa kuburikidza nekugocha uye mhepo yekudonha.

③ Kana paine ma sulfide anokuvadza mumhepo mune ore, senge arsenic, antimony, uye sulfide ye sulfide, iyo sulfide inosanganisirwa inowanikwa nekuyangarara inofanira kugochwa kupisa arsenic, sulfide nedzimwe simbi dziri mu concentrate kuita nyore Kune inovhuvhuta simbi oxides. , kukuya slag zvakare uye shandisa peni kuti ubvise mhepo inopisa oxides.

④ Kana chikamu chegoridhe chiri mu ore chiri munzvimbo yakasununguka, chikamu chegoridhe chinowirirana ne sulfide, uye chikamu chegoridhe chinoiswa mumaminerari e gangue.Zvicherwa zvakadaro zvinofanirwa kudzoserwa negiravhiti kupatsanurwa kudzoreredza goridhe remahara, uye kudzoreredza symbiosis ne sulfide kuburikidza ne flotation Kune goridhe, zvichienderana negoridhe riri mukati meiyo flotation tailings, zvinodikanwa kufunga kana kushandisa kemikari leaching.Iyo flotation concentrate inogona kukuyiwa zvakatsetseka yobva yanyudzwa zvakananga, kana zvinosara zvakatsva zvinogona kukuyiwa zvakatsetseka mushure mekupiswa uye nekunyudzwa.
