Saw dope musanganiswa weupfu hwematombo nemvura inogadzirwa panguva yekucheka uye kupenya kwemarble negranite.Nzvimbo zhinji dziri kuchamhembe kwenyika yedu dzakakosha mabhesi ekugadzira matombo, uye huwandu hukuru hwemadhaka esaha hunogadzirwa gore rega, uye stacking yayo inotora. kumusoro kwenzvimbo yakakura yezviwanikwa zvevhu.Ibwe rehupfu rine chimiro chakanaka uye rakaoma kurasa.Zviri nyore kubhururuka mudenga mumhepo ine simba, uye inoyerera murwizi nemvura inonaya mumazuva ekunaya, zvichikonzera kusvibiswa kwakakomba kwezvakatipoteredza.
The main gangue minerals in saw mud inosanganisira feldspar, quartz, calcite, dolomite, amphibole, etc. Iyo huru yesimbi minerals uye tsvina inosanganisira iron silicate yakadai se mechanical iron, magnetite, iron oxide, pyrite, uye biotite.Parizvino, kushandiswa kwakakwana nzira yedhaka yesaha inonyanya kugadzira zvidhinha zvekongiri zvine aerated uye kugadzira ceramic mbishi zvinhu mushure mekubvisa tsvina.Iyo yekare ine yakakura yekugadzirisa masimba uye iyo yekupedzisira ine yakakwirira yehupfumi mabhenefiti.
Beneficiation research
Muchinyorwa chino, iyo yakazara kushandiswa uye beneficiation bvunzo ongororo inoitwa kumumiriri akaona madhaka munzvimbo yeJining. Iyo yakakosha zvicherwa mumadhaka esaha ndeye feldspar, mechanical iron, magnetic iron, etc., uye tsvina inokuvadza imonite, biotite, muscovite, calcite, dolomite, hornblende, etc. Hukuru hwezvinhu hazvina kuenzana, zvimedu zvakakora zvinobva ku1-4mm uye mamwe -0.037mm madhaka akanaka.Pakati pavo, iyo mechanical iron inogadzirwa panguva yekugadziriswa uye iyo magineti iron mune mbishi. ore inogona kupatsanurwa zvine magineti kuita iron concentrate zvigadzirwa.Mushure mekuparadzana kwakasimba kwemagineti, tsvina ine iron yakaita selimonite, biotite, uye amphibole inogona kubviswa.Stone concentrate zvigadzirwa, chikamu chimwe nechimwe chemagineti tailings chinogona kushandiswa sezvidhinha zveaerated kana simende zvinhu, kuitira kuti uwane chinangwa chekushandiswa kwakazara.
1.Process kuyerera kutsunga
Kubatanidza zvimiro zvesawdust sampuli kuona maitiro ekubatsira: ore mbishi inosefa kuburikidza ne30 meshes-+30 mesh coarse-zviyo kugaya kusvika -30 mesh.
——-30 mesh yakasanganiswa sampuli yesimbi kupatsanurwa negubhu remagineti separator + flat plate + yakatwasuka mhete + yakatwasuka mhete yakasimba yemagineti simbi kubviswa-iyo concentrate inokamurwa kuita +300 mesh yepakati-zviyo feldspar concentrate zvigadzirwa uye -300 mesh yakanaka madhaka.——Iyo sludge yakanaka inobva yashandiswa kubvisa simbi kaviri kuburikidza nemagetsi emagetsi slurry kuwana yakanaka poda-giredhi yeconcentrate chigadzirwa.
2.Raw ore magnetic separation test
Ore yakasvibirira yakasefa ne30 meshes, uye mibairo yekuongorora inoratidzwa muTafura 1.
Tafura 1. Mhedzisiro yeBeneficiation uye Screening Test
Geya ore yakakasharara negoho re17.35% kusvika -30 mesh, sanganisa nechigadzirwa chiri pasi pesefa, uye pfuura nepakati peyakajairwa magineti yekuparadzanisa maitiro edhiramu remagineti separator + flat plate + vertical ring + vertical ring.Kuyerera kwemaitiro kunoratidzwa muMufananidzo 1, uye mhedzisiro yebvunzo inoratidzwa muTafura 2.
Mufananidzo 1. Iyo nzira inoyerera yeyakajairwa magineti yekuparadzanisa bvunzo yembishi ore.
Tafura 2. Migumisiro yezvakajairwa magnetic separation test
Iyo mbishi ore inoongororwa + ore kugaya + katatu-nguva simbi kubviswa kwakajairika bvunzo maitiro, uye yepakati uye yakaderera-yekupedzisira-kusimbisa zvigadzirwa zvinogona kuwanikwa negoho re92.57%, Fe2O3 yemukati ye0.525% uye kuchena kwe36.15%. Inofanirwa kutariswa kuchenesa iyo yakatsetseka-grained iron oxide uye iron silicate mudhaka rakanaka ine yakanaka yepakati, yakakwirira-munda electromagnetic slurry muchina mushure mekugadzika.
3.Kubviswa kwesimbi kubva mumatope akanaka
Yechipiri concentrate yeLihuan inoburitswa kubva kune yakanaka sludge pazasi -300 mesh kuburikidza nekufashukira, uye maitiro ekubvisa iron kaviri nemagetsi emagetsi slurry muchina anoshandiswa kuwana iyo yakanaka poda concentrate chigadzirwa.Kuyerera kwemaitiro kunoratidzwa muMufananidzo 2, uye mhedzisiro yebvunzo inoratidzwa muTafura 3.
Mufananidzo 2. Iyo nzira yekuyerera kweiyo yakanaka dope slurry simbi yekubvisa bvunzo
Tafura 3. Iron kubvisa indekisi yeakanaka madhaka slurry
Mushure mekuita magiredhi eLihuan concentrate, kuchena kwe +300 mesh medium-grain feldspar concentrate yakawedzera kubva pa36.15% kusvika 56.49%, uye kuchena kwedhaka rakanaka kwakadzikira kusvika 23.07%.-300 mesh yakanaka sludge inobviswa kubva musimbi kaviri ne electromagnetic slurry, uye ceramic-giredhi yakanaka poda chigadzirwa chine goho re42.31% uye kuchena kwe41.80% kunogona kuwanikwa.
3.Whole process test
Comprehensive bvunzo mamiriro uye zviratidzo kuita yose muitiro bvunzo.
Mufananidzo 3. Iyo yose nzira yekuona madhaka ekuedza maitiro
Tafura 4. Test zviratidzo zvehurongwa hwose
Attachment: Biscuits tembiricha 1200 ℃
Saw mud ore inoseferwa + pasi + weak magnetic separation + flat plate + vertical ring + vertical ring + grading electromagnetic slurry magnetic separation process kuti vawane iron ore ine goho re0.32% uye TFe giredhi re62.35%.Negoho 38.56% uye kuchena kwe54.69% yepakati-zviyo zvedongo giredhi feldspar concentrate zvigadzirwa uye goho 42.31% yekuchena kwe41.80% yakanaka poda yedongo giredhi concentrate zvigadzirwa;iyo yakazara goho remagineti tailings i18.81% , Inogona kushandiswa seyakabikwa yezvidhinha zveaerated.
Iyi tekinoroji maitiro inobvumira kushandiswa kwakadzama kwemadhaka esaha, uye inogona kuwana mabhenefiti epamusoro ehupfumi uye kukosha kwekuchengetedza nharaunda.
