Matope owona ndi osakaniza a ufa wa miyala ndi madzi opangidwa panthawi yodula ndi kupukuta miyala ya marble ndi granite.Madera ambiri kumpoto kwa dziko lathu ndi ofunika kwambiri a miyala yopangira miyala, ndipo matope ambiri amapangidwa chaka chilichonse, ndipo kuyika kwake kumafunika. kumtunda waukulu wa nthaka resources.The mwala ufa ali ndi maonekedwe abwino ndipo n'zovuta kutaya.Ndikosavuta kuwulukira mumlengalenga mumphepo yamphamvu, ndipo imathamangira mumtsinje ndi madzi amvula m'masiku amvula, zomwe zimawononga kwambiri chilengedwe.
Mchere waukulu wa gangue mumatope ocheka umaphatikizapo feldspar, quartz, calcite, dolomite, amphibole, etc. Mitsuko yayikulu yachitsulo ndi zonyansa zimaphatikizapo chitsulo chachitsulo monga chitsulo, magnetite, iron oxide, pyrite, ndi biotite.Pakali pano, kugwiritsidwa ntchito kwathunthu njira ya macheka matope makamaka kubala konkire aerated njerwa ndi kupanga ceramic zopangira pambuyo kuchotsa zosafunika.Zakale zimakhala ndi mphamvu zambiri zogwirira ntchito ndipo zotsirizirazi zimakhala ndi phindu lalikulu lazachuma.
Kafukufuku wopindulitsa
M'nkhani ino, mabuku magwiritsidwe ntchito ndi Beneficiation mayeso kafukufuku ikuchitika kwa nthumwi anaona matope mu Jining area.The ofunika mchere matope macheka ndi feldspar, makina chitsulo, maginito chitsulo, etc., ndi zonyansa zoipa ndi limonite, biotite, muscovite, calcite, dolomite, hornblende, etc. Kukula kwakuthupi ndi kosagwirizana, tinthu tating'onoting'ono tomwe timachokera ku 1-4mm ndi ena -0.037mm matope abwino. Pakati pawo, chitsulo chopangidwa ndi makina opangidwa panthawi yokonza ndi maginito chitsulo chosaphika. ore amatha kupatulidwa ndi maginito kukhala zinthu zachitsulo.Pambuyo pa kupatukana kwamphamvu kwa maginito, zonyansa zokhala ndi chitsulo monga limonite, biotite, ndi amphibole zimatha kuchotsedwa.Stone kuganizira mankhwala, gawo lililonse la maginito tailings angagwiritsidwe ntchito ngati njerwa aerated kapena zipangizo simenti, kuti akwaniritse cholinga magwiritsidwe mabuku.
1.Kutsimikiza kwamayendedwe
Kuphatikiza katundu wa utuchi chitsanzo kudziwa beneficiation ndondomeko: yaiwisi ore sieved kupyolera 30 meshes-+30 mauna coarse-tirigu akupera -30 mauna.
—--30 mauna osakanikirana achitsulo olekanitsa ndi ng'oma maginito olekanitsa + lathyathyathya mbale + ofukula mphete + ofukula mphete yamphamvu maginito chitsulo kuchotsa-concentrate - 300 mauna sing'anga-tirigu feldspar concentrate mankhwala ndi -300 mauna matope abwino.—-Dothi labwino limagwiritsidwa ntchito kuchotsa chitsulo kawiri kudzera pa electromagnetic slurry kuti apeze chinthu chabwino kwambiri chaufa.
2.Mayeso olekanitsa a ore yaiwisi
Ore yaiwisi idasefa ndi ma meshes 30, ndipo zotsatira zake zikuwonetsedwa mu Gulu 1.
Table 1. Zotsatira za Beneficiation and Screening Test
Pogaya ore coarse-grained ndi zokolola za 17,35% mpaka -30 mauna, kusakaniza mankhwala pansi sieve, ndi kudutsa njira ochiritsira maginito kulekana ndi ng'oma maginito olekanitsa + lathyathyathya mbale + ofukula mphete + ofukula mphete + ofukula mphete.Njira yoyendetsera ntchitoyi ikuwonetsedwa mu Chithunzi 1, ndipo zotsatira za mayeso zikuwonetsedwa mu Table 2.
Chithunzi 1. The ndondomeko otaya ochiritsira maginito kulekana mayeso yaiwisi ore.
Table 2. Zotsatira za mayesero ochiritsira maginito olekanitsa
The ore yaiwisi amafufuzidwa + ore akupera + katatu kuchotsa chitsulo njira ochiritsira mayeso ndondomeko, ndi pakati ndi otsika-kumapeto kuganizira mankhwala akhoza analandira ndi zokolola za 92.57%, ndi Fe2O3 zili 0,525% ndi whiteness 36.15%. Iyenera kuganiziridwa kuti imayeretsa chitsulo chosungunuka bwino ndi chitsulo cha silicate mumatope abwino ndi makina abwino kwambiri, makina apamwamba a electromagnetic slurry pambuyo pa gulu.
3.Kuchotsa chitsulo kuchokera kumatope abwino
Mfundo yachiwiri ya Lihuan imatulutsidwa ku sludge yabwino m'munsimu -300 mesh kupyolera mu kusefukira, ndipo ndondomeko yochotsa chitsulo kawiri ndi makina a electromagnetic slurry amagwiritsidwa ntchito kuti apeze mankhwala abwino a ufa.Njira yoyendetsera ntchitoyi ikuwonetsedwa mu Chithunzi 2, ndipo zotsatira zake zikuwonetsedwa mu Table 3.
Chithunzi 2. The ndondomeko otaya wabwino matope slurry chitsulo kuchotsa mayeso
Table 3. Chilolezo chochotsa chitsulo chamatope abwino
Pambuyo polemba malingaliro a Lihuan, kuyera kwa +300 mesh sing'anga-tirigu feldspar kumawonjezeka kuchokera 36.15% mpaka 56.49%, ndipo kuyera kwa matope abwino kunatsika mpaka 23.07%.-300 mauna zabwino sludge amachotsedwa chitsulo kawiri ndi electromagnetic slurry, ndi ceramic-kalasi yabwino ufa mankhwala ndi zokolola za 42,31% ndi whiteness 41,80% akhoza analandira.
3.Kuyesa kwa ndondomeko yonse
Comprehensive mayeso zinthu ndi zizindikiro kuchita lonse ndondomeko mayeso.
Chithunzi 3. Njira yonse yoyesa kuyesa matope
Table 4. Zizindikiro zoyesera za ndondomeko yonse
Chophatikizira: Kutentha kwa masikono 1200 ℃
Miyala yamatope imasefa + nthaka + yofooka maginito kupatukana + mbale yathyathyathya + mphete yowongoka + mphete yowongoka + yopangira ma elekitiroleti slurry maginito olekanitsa njira kuti mupeze zitsulo zachitsulo ndi zokolola za 0,32% ndi TFe kalasi ya 62.35%.Ndi zokolola za 38,56% ndi whiteness wa 54,69% wa sing'anga-tirigu ceramic kalasi feldspar maganizo mankhwala ndi zokolola za 42,31% ya whiteness 41,80% zabwino ufa ceramic kalasi kuganizira mankhwala;zokolola zonse za maginito tailings ndi 18.81% , Angagwiritsidwe ntchito ngati zopangira njerwa mpweya.
Njira yaukadauloyi imalola kugwiritsiridwa ntchito kokwanira kwa macheka amatope, ndipo imatha kupeza phindu lalikulu pazachuma komanso kufunika koteteza chilengedwe.
