Lub hauv paus muaj peev xwm tswj tau flotation tshuab thiab cov coj sib txuam rov qab thiab cov txiaj ntsig cov txheej txheem yog cov tsim nyog rau kev ua cov khoom sib txuam ntau cov hlau ua rau refractory sulfide ores. Lawv tau raug tshaj tawm thiab thov hauv Xitieshan txhuas-zinc mine ntawm Qinghai Western Mining thiab Nanjing Qixiashan txhuas-zinc mine.
Raws li cov qauv sib xyaw ua ke ntawm cov khoom lag luam polymetallic uas muaj cov zaub mov qis qis, Dingjiashan qhov chaw ua haujlwm tau ua ntau qhov kev kuaj sim ntau yam thiab ua ke nrog cov txiaj ntsig ntawm kev ntsuam xyuas kev lag luam los txiav txim siab tias qhov rov qab los ntawm txhuas, zinc thiab nyiaj tuaj yeem nkag siab zoo dua los ntawm thawj lub peev xwm tswj tau flotation technology, thiab cov txheej txheem txhim kho Cov hlau sulfide cov zaub mov thiab cov khoom siv hlau nplaum hauv cov hlau tau zoo dua cais nyias, thiab nyob rau lub hauv paus no, tus thawj Meixian Concentrator tau hloov pauv tau. Tom qab kev hloov pauv tiav, kev rov ua tiav ntawm cov hlau muaj txiaj ntsig nyob rau hauv high-sulfur refractory lead-zinc-silver polymetallic ore tuaj yeem ua kom zoo los ntawm kev kho lub peev xwm thawj, pH tus nqi ntawm slurry, thiab qhov ntau ntawm cov tshuaj reagent. Tus nqi ntawm cov hmoov txhuas rov qab los tau nce ntawm 85% mus rau 87%. Tus nqi rov qab ntawm zinc tau nce los ntawm 66% mus rau 76%, tus nqi rov qab ntawm zinc tau nce ntxiv los ntawm 92% mus rau 94%, thiab tus nqi rov qab ntawm cov hlau sulfide tsawg tau nce mus txog 87%, thiab tus nqi rov qab ntawm magnetite muaj nce mus txog 71%. Qhov sorting index yog qhov zoo tagnrho.
Hauv qab keeb kwm ntawm kev txhim kho kev lag luam sai hauv peb lub teb chaws tau ntau caum xyoo, cov peev txheej hauv cov ntxhia tau tsim nyob rau ntawm qhov loj, thiab maj mam qhia txog kev hloov ntawm kev txom nyem, meej meej thiab lwm yam. Txhawm rau kom muaj txiaj ntsig zoo npaum li cas ntawm cov peev txheej hauv lub teb chaws xav tau, kev tsim thev naus laus zis tshiab, kev siv tswv yim thiab khoom siv tau tsim kho nrog lawv. Cov noob nyom yog qhov ceev heev. Cov thev naus laus zis no thiab nws qhov kev tshawb fawb tuaj yeem qhia qhov tseeb kev tsim cov khoom siv sib txawv ntawm cov polymetallic nyuaj-rau-cais sulfide mines, tshwj xeeb tshaj yog nyob hauv ntau yam ntawm cov mines uas muaj cov khoom muaj nqis tooj liab, txhuas, zinc, thiab sulfide. Cov thev naus laus zis no txhim kho kom rov qab los ntawm cov khoom muaj nqes xws li tooj liab, txhuas, thiab zinc. Tib lub sijhawm, daim ntawv thov ntawm cov thev naus laus zis los ua kom muaj txiaj ntsig cov txheej txheem tau txais txiaj ntsig zoo tuaj yeem rov qab pyrite cov khoom lag luam, cov khoom siv hlau sib nqus thiab lwm yam khoom siv inorganic.
