I-lead-zinc yam, indlela yokukhetha?

Phakathi kweentlobo ezininzi zeeminerali, i-ore ye-lead-zinc yinto enzima kakhulu ukuyikhetha.Ngokuqhelekileyo, i-lead-zinc ore inee-ore ezihlwempuzekileyo kunezityebi ezityebileyo kwaye izinto ezinxulumene nazo zinzima kakhulu.Ngoko ke, indlela yokwahlula ngokufanelekileyo ilothe kunye ne-zinc ores ikwangumba obalulekileyo kwishishini lokulungisa izimbiwa.Okwangoku, i-lead kunye ne-zinc minerals ekhoyo ekusetyenzisweni kwimizi-mveliso ikakhulu i-galena kunye ne-sphalerite, kwaye iquka i-smithsonite, i-cerussite, njl njl. Ngokomlinganiselo we-oxidation, iiminerali ze-lead-zinc zinokwahlulwa zibe yi-lead-zinc sulfide ore, i-lead- i-zinc oxide ore, kunye ne-lead-zinc ore edibeneyo.Ngezantsi siza kuhlalutya ngokuthe ngqo inkqubo yokwahlula i-lead-zinc ore ngokusekelwe kwiqondo le-oxidation ye-lead-zinc ore.

Inkqubo yokwahlula i-lead-zinc sulfide ore
Phakathi kwentsimbi ye-lead-zinc sulfide kunye ne-lead-zinc oxide ore, intsimbi ye-lead-zinc sulfide kulula ukuyihlela.I-lead-zinc sulfide ore ihlala iqulethe i-galena, i-sphalerite, i-pyrite, kunye ne-chalcopyrite.Iiminerali eziphambili ze-ganggue ziquka i-calcite, i-quartz, i-dolomite, i-mica, i-chlorite, njl. Ngoko ke, ngokuhambelana nobudlelwane obufakwe kwiiminerali eziluncedo ezifana nelothe kunye ne-zinc, inqanaba lokugaya linokukhetha ngokuthe ngqo inkqubo yokugaya okanye i-multi-stage grinding process. .

Inkqubo yokugaya yenqanaba elinye isoloko isetyenziselwa ukusetyenzwa kwe-lead-zinc sulfide ores kunye nobukhulu oburhabaxa beenkozo okanye ubudlelwane obulula be-symbiotic;

Inkqubo yokugaya izigaba ezininzi iqhuba i-lead-zinc sulfide ores kunye nobudlelwane obunzima bokuxhamla okanye ubungakanani bamaqhekeza amancinci.

Kwizinto ezikrwada ze-lead-zinc sulfide, ukugaywa kweentsalela zezimbiwa okanye ukucolwa kwe-coarse concentrate regrinding kudla ngokusetyenziswa, kwaye inkqubo yokugaya intsimbi ephakathi ayifane isetyenziswe.Kwinqanaba lokwahlula, i-lead-zinc sulfide ore ihlala ithatha inkqubo yokudada.Iinkqubo zokudada ezisetyenziswayo ngoku zibandakanya: inkqubo yokudada okuphambili, inkqubo yokudada okuxutyiweyo, njl.njl. Ukongeza, ngokusekwe kwinkqubo yesiqhelo yeflotation ethe ngqo, iinkqubo ezilinganayo zokudada, iinkqubo ezirhabaxa nezicolekileyo zokwahlula, iinkqubo zokuqukuqela kothotho lwesebe, njl.njl. ezikhethwa ikakhulu ngokusekelwe kubungakanani bazo obuhlukeneyo bamasuntswana kunye nobudlelwane obuzinzisiweyo.

Phakathi kwabo, inkqubo yokudada elinganayo ineenzuzo ezithile kwinkqubo yokudada yentsimbi ye-lead-zinc ore kuba idibanisa inkqubo ye-flotation ye-ores enzima-ukwahlula kunye ne-ores ekulula ukwahlula kwaye idla iikhemikhali ezincinci, ngakumbi xa zilula. -ukwahlula ore kwintsimbi ekrwada.Xa kukho iintlobo ezimbini zeeminerali zelothe kunye nezinc ezidadayo kwaye kunzima ukudada, inkqubo yokudada lolona khetho lufanelekileyo.

Lead zinc oxide ore inkqubo yokwahlula
Isizathu sokuba kutheni i-lead-zinc oxide ore inzima kakhulu ukukhetha kune-lead-zinc sulfide ore ikakhulu ngenxa yezixhobo zayo ezintsonkothileyo, amacandelo ahambelanayo angazinzanga, ubungakanani besuntswana elifakwe kakuhle, kunye nokuhamba okufanayo kweeminerali ze-lead-zinc oxide kunye neeminerali ze-ganggue. kunye ne-mineral slime., okubangelwa yimiphumo emibi yeetyuwa ezinyibilikayo.

Phakathi kwe-lead-zinc oxide ores, ezo zinexabiso lezoshishino ziquka i-cerusite (PbCO3), i-lead vitriol (PbSO4), i-smithsonite (ZnCO3), i-hemimorphite (Zn4 (H2O) [Si2O7] (OH) 2), njl. Phakathi kwabo, i-cerusite , i-lead vitriol kunye ne-molybdenum lead ore kulula kakhulu ukwenza i-sulfide.I-sulfide agents ezifana ne-sodium sulfide, i-calcium sulfide kunye ne-sodium hydrosulfide ingasetyenziselwa unyango lwe-sulfurization.Nangona kunjalo, i-lead vitriol idinga ixesha elide lokunxibelelana ngexesha lenkqubo ye-vulcanization.I-agent ye-vulcanizing Umthamo nawo mkhulu kakhulu.Nangona kunjalo, i-arsenite, i-chromite, i-chromite, njl njl. kunzima kwi-sulfide kwaye ayinakuhamba kakuhle.Inani elikhulu lamaminerali aluncedo liya kulahleka ngexesha lenkqubo yokwahlula.Kwi-lead-zinc oxide ores, inkqubo yokudada ephambili ikhethwa ngokubanzi njengeyona ndlela iphambili yokwahlula, kwaye imisebenzi ye-desliming yenziwa ngaphambi kokuba i-flotation iphucule izalathisi zokudada kunye nomthamo weekhemikhali.Ngokumalunga nokukhethwa kwe-arhente, i-xanthate ye-long-chain ingumqokeleli oqhelekileyo kunye osebenzayo.Ngokweziphumo ezahlukeneyo zovavanyo, inokuthi ithathelwe indawo ngeZhongoctyl xanthate okanye iNombolo ye-25 iyeza elimnyama.Abaqokeleli be-asidi enamafutha afana ne-oleic acid kunye nesepha yeparafini ene-oxidized ukukhetha kakubi kwaye bafanelekele kuphela i-ores ye-lead ephezulu kunye ne-silicates njengeyona gangue ephambili.
