Iyo Sino-German Kiyi Laboratory yeMagnetoelectricity uye Intelligent Mineral Processing yeHuate Kambani inoitisa huwandu hukuru hwekuyedza kubatsiridza pamatehwe egoridhe munzvimbo yeYantai.Iyo mikuru yemaminerari ezvikamu zvegoridhe tailings ndeye gangue zvicherwa senge quartz, feldspar uye calcite, uye shoma shoma yemakanika Iron, magineti iron, iron oxide, titanium oxide, iron silicate, iron sulfide uye kumwe kusvibiswa. machira egoridhe anowanzo 200 mesh 50-70%, saizi yechikamu chakafanana, uye ine idiki dhaka rakanaka.Kusachena kukuru kweFe2O3 kuri 1-3%, TiO2 zviri mukati 0.1-0.3%, CaO zvirimo 0.12-1.0%, uye kuchena kwemasara egoridhe i5-20%.Pane mimwe misiyano mukuumbwa kwemiswe inogadzirwa neakasiyana concentrators.Mimwe miswe ine yakakwirira yeSiO2, kana ine spodumene, sericite, nezvimwewo. Zvizhinji zvacho ndezvemhando yefeldspar-quartz pegmatite type, ine kukosha kwekushandisa zvakare.
Huate Company yakagadzira "magnetic separation-gravity separation" yakasanganiswa yebeneficiation process, uye yakawana mvumo yekugadzira patent munaGunyana 2020. Zvirimo patent ndeye "nzira yekushandiswa yakazara yemasimbi egoridhe ane goridhe, simbi uye feldspar. Parizvino, zvinopfuura. gumi makuru maindasitiri ekushandisa akaitwa muYantai, Shandong, iyo yakakura kwazvo inogona kugadzira zviuru zvisere zvematani egoridhe pazuva. Mukuita uku, midziyo yekubatsirikana yepamberi senge vibrating screen, spiral chute, tafura inozunguza, dhiramu remagineti separator. , yakanyorova yakasimba magineti ndiro yemagineti separator, yakatwasuka mhete yakakwira gradient magineti separator, uye electromagnetic slurry magineti separator inoshandiswa mukubatana.Ndichiri kutambira feldspar yemhando yepamusoro kubva kumaswe, zvigadzirwa zvakakosha zvakaita semagineti, zvicherwa zvine goridhe, simende mbishi, uye zvigadzirwa zvekugadzira zvidhinha zvinodzoserwa zvakare kuti zvione kushandiswa kwakadzama kwemasimbi egoridhe uye kuburitsa zero zvachose. - nzira yekutenderera.
Vertical mhete yakakwira gradient magineti separator uye electromagnetic slurry yakakwira gradient magineti separator inoshandiswa mukugadzira machira egoridhe chirongwa.
