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 hwemasaha dope hunogadzirwa gore rega, uye stacking yayo inotora. kumusoro kwenzvimbo huru yezviwanikwa zvevhu.Ibwe rehupfu rine chimiro chakanaka uye rakaoma kurasa. Zviri nyore kubhururuka mudenga mumhepo ine simba, uye inoyerera ichipinda murwizi nemvura inonaya mumazuva emvura, zvichikonzera kusvibiswa kwakakomba kwezvakatipoteredza.
The main gangue minerals in saw mud inosanganisira feldspar, quartz, calcite, dolomite, amphibole, etc. Iyo huru yesimbi zvicherwa 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 uye kugadzira zvedongo mbishi mushure mekubvisa tsvina. Iyo yekare ine hukuru hwekugadzirisa masimba uye iyo yekupedzisira ine hupfumi hwepamusoro.
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, simbi yemagetsi inogadzirwa panguva yekugadzira uye simbi yemagineti mune mbishi. ore inogona kupatsanurwa zvine magineti kuita iron concentrate zvigadzirwa. Mushure mekuparadzana kwakasimba kwemagineti, tsvina ine iron-yakadai 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 yakasvibirira 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 yakatarisana inokamurwa kuita +300 mesh yepakati-zviyo feldspar concentrate zvigadzirwa uye -300 mesh yakanaka madhaka.——Iyo sludge yakanaka inozoshandiswa 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 yakaomeswa negoho re17.35% kusvika -30 mesh, sanganisa nechigadzirwa pasi pesefa, uye pfuura neyakajairwa 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 yekuyerera kweyakajairwa magineti yekuparadzanisa bvunzo yembishi ore.
Tafura 2. Migumisiro yezvakajairwa magnetic separation test
Iyo mbishi ore inoongororwa + ore kugaya + katatu-nguva kubviswa kwesimbi kwakajairika bvunzo maitiro, uye yepakati uye yakaderera-yekupedzisira concentrate 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 mekugadzirisa Lihuan concentrate, kuchena kwe +300 mesh medium-grain feldspar concentrate yakawedzera kubva pa36.15% kusvika 56.49%, uye kuchena kwedhaka rakanaka kwakaderera 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. Zviratidzo zvekuedza zvemuitiro wose
Kunamatira: Biscuits tembiricha 1200 ℃
Saw mud ore inosefa + pasi + isina simba remagineti separation + flat plate + vertical ring + vertical ring + grading electromagnetic slurry magnetic separation process kuti vawane simbi 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 zvine aerated.
Iyi tekinoroji maitiro inobvumira kushandiswa kwakadzama kwemadhaka esaha, uye inogona kuwana mabhenefiti epamusoro ehupfumi uye kukosha kwekuchengetedza nharaunda.
