Kiyobora-zinc, guhitamo gute?

Mu bwoko bwinshi bw'amabuye y'agaciro, ubutare-zinc ni ubutare bworoshye guhitamo.Muri rusange, ubutare-zinc bufite ubutare bubi kuruta amabuye akungahaye kandi ibice bifitanye isano biragoye.Kubwibyo, uburyo bwo gutandukanya neza amasasu na zinc nacyo nikibazo cyingenzi mubikorwa byo gutunganya amabuye y'agaciro.Kugeza ubu, imyunyu ngugu ya sinc na zinc iboneka mu gukoresha inganda ahanini ni galena na sphalerite, kandi harimo na smithsonite, cerussite, nibindi. ubutare bwa zinc, hamwe nuruvange rwa gurş-zinc.Hano hepfo tuzasesengura byumwihariko inzira yo gutandukanya ubutare-zinc dushingiye kurwego rwa okiside yubutare bwa zinc.

Kurongora-zinc sulfide ubutare bwo gutandukana
Mu bucukuzi bw'amabuye y'agaciro ya sulfide na sisitemu yo mu bwoko bwa gurşide-zinc, ubutare bwa zinc sulfide biroroshye gutondeka.Amabuye ya gurş-zinc sulfide akunze kuba arimo galena, sphalerite, pyrite, na chalcopyrite.Amabuye y'agaciro ya gangue arimo calcite, quartz, dolomite, mika, chlorite, nibindi. .

Inzira imwe yo gusya ikoreshwa kenshi mugutunganya amabuye ya gurş-zinc sulfide hamwe nubunini bwimbuto nini cyangwa imibanire yoroshye ya symbiotic;

Inzira nyinshi zo gusya zitunganya inzira-zinc sulfide amabuye hamwe nubusabane bugoye cyangwa ingano nziza.

Kumabuye ya sisitemu-zinc sulfide, imirizo igarura cyangwa igororotse yibanda cyane ikoreshwa, kandi uburyo bwo guhinduranya amabuye yo hagati ntibukoreshwa gake.Mu cyiciro cyo gutandukana, ubutare-zinc sulfide ubutare bukoresha inzira ya flotation.Muri iki gihe ikoreshwa rya flotation harimo: inzira yibanze ya flotation, inzira ivanze ya flotation, nibindi. Byongeye kandi, ukurikije uburyo busanzwe bwo guhinduranya ibintu, inzira zingana zingana, uburyo bworoshye bwo gutandukana, uburyo bwo gutandukanya amashami, nibindi byateguwe, zikaba zatoranijwe cyane cyane zishingiye kubunini bwazo butandukanye nubusabane bwashizwemo.

Muri byo, uburyo buringaniye bwa flotation bufite inyungu zimwe murwego rwo guhinduranya amabuye y'agaciro ya gurş-zinc kuko ahuza inzira yo guhinduranya amabuye y'agaciro atoroshye-gutandukana kandi byoroshye-gutandukanya amabuye y'agaciro kandi akoresha imiti mike, cyane cyane iyo hari byoroshye -kutandukanya amabuye y'agaciro mu bucukuzi.Iyo hari ubwoko bubiri bwa sisitemu na minerval zinc zireremba kandi bigoye kureremba, inzira ya flotation nuburyo bwiza bwo guhitamo.

Kuyobora inzira ya zinc oxyde yo gutandukanya
Impamvu ituma amabuye y'agaciro ya gurşide-zinc bigoye guhitamo kuruta amabuye y'agaciro ya gurş-zinc sulfide biterwa ahanini n'ibigize ibintu bigoye, ibice bifitanye isano bitajegajega, ingano y’ibice byinjizwamo neza, hamwe no kureremba bisa n’amabuye y'agaciro ya gurş-zinc na minerval ya gangue. amabuye y'agaciro., biterwa n'ingaruka mbi z'umunyu ushonga.

Mu bucukuzi bw'amabuye y'agaciro ya aside-zinc, abafite agaciro mu nganda harimo cerusite (PbCO3), vitriol (PbSO4), smithsonite (ZnCO3), hemimorphite (Zn4 (H2O) [Si2O7] (OH) 2), n'ibindi Muri bo, cerusite , gurşide vitriol na molybdenum ubutare bworoshye byoroshye sulfide.Ibikoresho bya sulfide nka sodium sulfide, calcium sulfide na sodium hydrosulfide birashobora gukoreshwa mu kuvura sulfurizasi.Nyamara, vitriol ya gurşide isaba igihe kinini cyo guhura mugihe cyibirunga.Umukozi wa volcanizing Igipimo nacyo kinini.Nyamara, arsenite, chromite, chromite, nibindi biragoye sulfide kandi ifite kureremba nabi.Umubare munini wamabuye y'agaciro azabura mugihe cyo gutandukana.Kumabuye ya gurş-zinc oxyde, inzira yibanze ya flotation muri rusange yatoranijwe nkigikorwa nyamukuru cyo gutandukana, kandi ibikorwa bya desliming bikorwa mbere ya flotation kugirango tunonosore ibipimo bya flotation hamwe na dosiye yimiti.Kubyerekeranye no gutoranya abakozi, urunigi rurerure xanthate ni rusange kandi rukusanya neza.Ukurikije ibisubizo bitandukanye by'ibizamini, birashobora kandi gusimburwa na Zhongoctyl xanthate cyangwa No 25 imiti yirabura.Ikusanyirizo rya aside irike nka acide oleic hamwe nisabune ya paraffine ya okiside ifite amahitamo mabi kandi irakwiriye gusa amabuye yo mu rwego rwo hejuru yo mu rwego rwo hejuru hamwe na silicates nkagatsiko gakomeye.
