Dab tsi yog cov txheej txheem ntws rau cov txiaj ntsig pyrite?
Flotation Tshuab
Kev piav qhia ntxaws txog peb cov txheej txheem tseem ceeb
1. Flotation tshuab: Qhov tseem ceeb tshaj plaws thiab siv tau zoo
Flotation yog cov thev naus laus zis tseem ceeb rau kev sib cais pyrite, tshwj xeeb tshaj yog tsim rau kev ua kom zoo -grained ores nrog qib qis.
Lub hauv paus ntsiab lus: Siv lub ntuj lossis hloov pauv hydrophobicity ntawm pyrite nto, reagents yog ntxiv kom nws ua raws li huab cua npuas, cais tawm ntawm cov pob zeb pov tseg.
Common Reagents:
Cov khoom siv: Butyl xanthate, isopropyl xanthate, thiab lwm yam.
Txiv Hmab Txiv Ntoo: Tsis yog . 2 roj (pine oil).
Kev hloov kho: Hauv cov txheej txheem tshwj xeeb, oxalic acid lossis tooj liab sulfate tuaj yeem siv los ua cov activators, los yog txiv qaub ua rau kev nyuaj siab (siv cais pyrrhotite thiab pyrite).
Cov xwm txheej siv tau: Feem ntau cov pyrite ores, tshwj xeeb tshaj yog thaum siab - qib sulfur concentrate (S > 40%).
2. Kev sib cais ntawm lub ntiajteb txawj nqus: Tsawg-Tus nqi, Environmentally Friendly Pre-Txoj Kev Txhim Kho
Rau ntxhib-grained lossis siab-qib pyrite ores, kev sib cais lub ntiajteb txawj nqus tuaj yeem txo cov nqi.
Khoom siv: Jig tshuab (rau coarse hais), co rooj (rau cov khoom zoo).

Qhov zoo: Yuav tsum tsis muaj cov tshuaj reagents, tus nqi qis, tus phooj ywg ib puag ncig, thiab feem ntau siv ua ntej - ua kom muaj txiaj ntsig zoo ua ntej flotation.
Cov ntaub ntawv kawm: Ib qho carbonaceous pyrite deposit nyob rau hauv Guizhou xeev tuaj yeem yog thawj lub ntiajteb txawj nqus- sib cais siv cov ntxhuav tuav kom tau txais cov ntsiab lus ntxhib nrog qib sulfur ntawm 28.96% thiab tus nqi rov qab ntawm 72.19%. Tom qab flotation yields ib qho tsim nyog sulfur concentrate nrog qib kawg ntawm 42.76%.

3. Sib Nqus Sib Nqus: Feem ntau yog siv los cais cov hlau thiab sulfur.
Thaum magnetite lossis pyrrhotite cuam tshuam nrog pyrite, sib nqus sib nqus yog ib qho tseem ceeb ntawm kev sib cais.
Txheej Txheem: Ib qho ua ke "magnetic{0}}flotation-magnetic" txheej txheem.
Kauj Ruam 1: Tsis muaj zog sib nqus sib cais kom rov qab muaj zog hlau nplaum hlau.
Kauj Ruam 2: Flotation ntawm cov khoom sib nqus kom tshem tawm cov pyrite (pyrrhotite lossis pyrite).
Kauj Ruam 3: Qhov thib ob sib nqus sib nqus kom thaum kawg tau txais qib siab - qib hlau concentrate.
Cov txiaj ntsig: Siv cov txheej txheem no, ib qho nyuaj - rau- txheej txheem ore los ntawm Liaoning Xeev thaum kawg tau txais cov hlau tsim nyog nrog qib hlau ntawm 67.20% thiab cov ntsiab lus sulfur ntawm tsuas yog 0.36%, thiab sulfur concentrate nrog qib sulfur ntawm 32.30% kuj tau rov qab los.
Cov ntsiab lus thiab cov lus pom zoo
Kev xaiv ntawm txheej txheem nyob ntawm koj lub hom phiaj:
Yog tias lub hom phiaj tseem ceeb yog kev rov qab los ntawm leej faj, kev sib koom ua ke "kev sib cais ntawm lub ntiajteb txawj nqus + flotation" yog kev sib xyaw ua ke zoo tshaj plaws, muab tus nqi siab tshaj - ua tau zoo.
Yog tias cov ore muaj cov nqi hlau ntau dua, yuav tsum muaj txheej txheem "sib nqus-flotation-magnetic" los ua kom hlau thiab txo cov sulfur.
Rau me me - teev kev ua haujlwm lossis ua cov pob zeb khib nyiab, yooj yim sib cais (jigging lossis co rooj) yog qhov txaus thiab kev lag luam.
Cov kev ntsuam xyuas tau txais txiaj ntsig pom zoo: Txawm li cas los xij ntawm cov txheej txheem tau xaiv, kev sim tshuaj ntsuam xyuas cov txiaj ntsig ntawm cov ore tshwj xeeb tau pom zoo. Qhov loj me me faib thiab kev sib raug zoo (pure pyrite los yog pyrrhotite) ntawm pyrite los ntawm cov hauv paus chiv keeb sib txawv heev, yuav tsum muaj kev ntsuam xyuas los txiav txim seb qhov kev sib tsoo zoo tshaj plaws thiab cov txheej txheem reagent.
