Vim hais tias cov nplua-grained tailings pov txoj siv yog nqaim thiab qhov kev ncua deb ntawm qib ntawm cov tailings siv thiab cov casing tsis hloov loj, lub baffle yuav nyob ze rau lub casing. Nyob rau hauv txoj kev no, qib tailings tsis nce ntau, uas yog qhov zoo rau kev txhim kho kev mloog zoo.
Kev xyaum ntau lawm tau ua pov thawj tias qhov kev xaiv qhov loj me muaj qhov cuam tshuam zoo rau kev sib nqus sib nqus qhuav. Txhawm rau txo qhov cuam tshuam no, kev ua haujlwm tiag tiag yuav tsum tau txiav txim siab raws li qhov xwm txheej tshwj xeeb. Nyob rau hauv Beijing Iron Mine, cov ores uas tau xaiv qhov loj me ntawm 200 mesh accounting rau 25 feem pua yog muab faib ua qib ntxhib nrog -200 mesh ntsiab lus ntawm 5 feem pua -8 feem pua thiab qib zoo nrog -200 mesh cov ntsiab lus ntawm 50 feem pua -60 feem pua . Ib qho kev ntsuas zoo ntawm kev xaiv tau txais.
Cov dej noo ntawm ore muaj qee yam cuam tshuam rau kev sib nqus sib nqus qhuav, tshwj xeeb tshaj yog nyob rau hauv kev sib cais zoo. Vim tias cov dej yuav txhim kho "sib nqus pawg" kev sib txuas, yog li cov "sib nqus pawg" sib xyaw ua ke kom ruaj khov, thiab, yooj yim rau lo rau ntawm lub plhaub, txawm hais tias nce centrifugal quab yuam, tsis tuaj yeem txhim kho cov ntsuas, tab sis qee zaum hnyav dua. Yog li ntawd, thaum lub ore noo noo yog loj nyob rau hauv lub caij los nag, qhov kev faib ua feem ntawm block ore yuav tsim nyog nce kom txo tau cov dej ntsiab lus thiab av nkos ntsiab lus ntawm ore. Thaum cov ntsiab lus dej muaj kev cuam tshuam zoo rau kev sib cais qhov ntsuas, kev ua haujlwm tuaj yeem hloov kho los ntawm kev txo cov ore pub thiab ua kom muaj cov khoom tsim nyog concentrated. Thaum cov dej ntsiab lus ntawm cov ntxhib ntxhib yog tsawg dua 2 feem pua, nws tsis muaj qhov cuam tshuam loj rau kev sib cais. Thaum cov dej ntsiab lus ntawm cov ore qib zoo yog tsawg dua 2.5 feem pua, nws tsis muaj qhov cuam tshuam loj rau qhov sib cais.
Qhov sib nqus ntawm ore kuj muaj feem cuam tshuam rau qhov sib nqus sib nqus index. Thaum cov hlau nplaum sib nqus siab, qib tailings yuav tsum tau txo kom deb li deb tau thiab tus nqi rov qab yuav tsum tau txhim kho raws li kev ua kom zoo ntawm kev mloog zoo. Thaum tus nqi sib nqus tsis tshua muaj, lub luag haujlwm tseem ceeb yuav tsum ua kom ntseeg tau qib ntawm kev mloog zoo, tab sis kuj tseem ua tib zoo saib xyuas kom txo qis qib ntawm tailings.
