Imayini ye-Lead-Zinc, ingakhetha kanjani?

Phakathi kwezinhlobo eziningi zamaminerali, i-lead-zinc ore iyi-ore enzima ukuyikhetha. Ngokuvamile, ukuhola, i-zinc ore kunama-ores ampofu kakhulu kune-ores enothile kanye nezinto ezihambisana nazo ziyinkimbinkimbi kakhulu. Ngakho-ke, indlela yokuhlukanisa kahle i-Holy neZinc Ares futhi kuyinkinga ebalulekile embonini yokusebenza kwamaminerali. Njengamanje, amaminererali aholayo kanye nama-zinc atholakala ekusetshenzisweni kwezimboni ikakhulukazi ikakhulukazi i-spharerite, futhi afaka futhi ama-smithsonite, amaminerali e-lead-zinc angahlukaniswa ngamanani okuhola-zinc sulfide ore, ukuhola I-zinc onide ore, kanye ne-lead-zinc ore exubile. Ngezansi sizokuhlaziya ngokuqondile inqubo yokuhlukanisa ye-lead-zinc ore ngokususelwa kwi-oxidation degree of thead-zinc ore.

Inqubo yokuhlukaniswa kwe-lead-zinc sulfide are
Phakathi kokuhola-zinc sulfide ore kanye no-lead-zinc ongi, i-lead-zinc sulfide ore kulula ukuhlela. I-Lead-Zinc Sulfide Ore imvamisa iye yahlala i-Galena, i-Spalerite, i-pyrite, ne-chalcoryyrite. Amaminerali amakhulu weGangz afaka i-carcite, i-quartz, i-dolomite, i-mica, i-chlorite, njll. Ngakho-ke, ngokusho kobudlelwano obushumekiwe bamaminerali abalulekile anjengokuhola noma inqubo yokugaya izigaba eziningi .

Inqubo yokugaya esiteji esisodwa ivame ukusetshenziselwa ukucubungula ama-ores we-lead-zinc sulfide ngosayizi wokusanhlamvu kwama-coarbilic noma ubudlelwane obulula;

Inqubo yokugaya esiteji eminingi icubungula i-lead-zinc sulfide ores ngobudlelwano obuyinkimbinkimbi bokuxhumana noma osayizi wezinhlayiyana ezinhle.

Okwe-Holy-Zinc Sulfide Ores, Ukulungiswa kabusha kwe-Tailings noma i-Coarse Precentar Esigabeni sokwehlukanisa, i-lead-zinc sulfide ore ivame ukwamukela inqubo ye-flotation. Izinqubo ze-flotation ezisetshenzisiwe njengamanje zifaka: inqubo ebaluleke kakhulu, inqubo exubile ye-flotation, njll. Ngaphezu kwezinqubo ezingejwayelekile, izinqubo zokugeleza zokwehlukana ezibucayi, njll. Zithuthukisiwe, okukhethwe ikakhulu ngokusekelwe osayizi bawo obuhlukile bezinhlayiya kanye nobudlelwano obushumekiwe.

Phakathi kwazo, inqubo enjalo ye-flotation inezinzuzo ezithile kwinqubo yokuhola ye-lead-zinc ngoba ihlanganisa inqubo yokufakelwa kwamakhemikhali ahlukile kanye namakhemikhali ahlukene futhi adla amakhemikhali amancane, ikakhulukazi uma kulula -uku-ores okuhlukile ku-ore. Lapho kunezinhlobo ezimbili zokuhola kanye namaminerali ama-zinc antantayo futhi anzima ukuntanta, inqubo yokuthwebula isinqumo esifanelekile.

Hola i-zinc ongi i-ore ukwehlukaniswa kwenqubo yokuhlukanisa
Isizathu esenza kuholele-u-ore-oride o-oide kunzima ukukhetha kunokuhola kwezonto ezijwayelekile, izingxenye ezihambisana nezinto ezihlotshaniswa, nosayizi ofanayo wezinhlayiyana, kanye nokufunyaneka okufanayo kwamaminerali e-Gangee kanye ne-mineral slime. , okubangelwa yimiphumela emibi kasawoti oncibilikayo.

Phakathi kokuhola-i-zinc onide oride, labo abanenani lezimboni bafaka i-arrite (PBCO3), i-vitriol (i-Smithso4), i-smithsonite (zgo3), i-SI2O7] (OH) 2), njll. 2), njll. , ukuhola i-vitriol ne-molybdenum ore kulungile ku-sulfide. Ama-sulfiviting agents anjenge-sodium sulfide, i-calcium sulfide ne-sodium hydrosulfide ingasetshenziselwa ukwelashwa kwe-sulfurization. Kodwa-ke, i-vitriol eholayo idinga isikhathi eside sokuxhumana ngesikhathi senqubo yokuvuselela. I-ejenti ye-Vulcaning umthamo nayo inkulu kakhulu. Kodwa-ke, i-Arsenite, chromite, chree, njll. Inani elikhulu lamaminerali awusizo azolahleka ngesikhathi senqubo yokuhlukanisa. Ukuze uthole i-Lead-Zic onide Ores, inqubo ebaluleke kakhulu ye-flotation ikhetheke njengenqubo enkulu yokuhlukanisa, futhi imisebenzi yokudla ye-desteliming yenziwa ngaphambi kokuthwebula ukuthuthukisa izinkomba ze-flotation kanye nemithamo yamakhemikhali. Ngokuya kokukhethwa kwe-ejenti, i-xanthate ende ye-xanthate ingumqoqi ojwayelekile futhi osebenzayo. Ngokusho kwemiphumela ehlukene yokuhlola, ingashintshwa nge-zhongoctyl xanthate noma Cha. 25 Imithi Emnyama. Abaqoqi be-fatty acid njenge-oleic acid kanye ne-oxidised paraffin insipho banokukhetha kabi futhi balungele kuphela ama-ores ahola amabanga aphezulu ngezinsimbi eziphakeme njenge-milicates njenge-gang gang.
