Kushandiswa kwakadzama kwemisara ishoko rinopisa munharaunda yezvicherwa mumakore achangopfuura, uye tsvakiridzo pamusoro pemashandisirwo akazara emisara yegoridhe yakaitwa zvakare. Zvinonzwisiswa kuti kugadzirwa kwemarara emigodhi yegoridhe munyika yangu kwasvika matani anopfuura bhiriyoni imwe nemazana mashanu, asi mwero wekushandiswa wakakwana uri pasi pe20%.Parizvino, nzira yakanakisa yekuona kuraswa kwegoridhe kusina tsvina uye kusina ngozi. miswe pamigodhi inosanganisira nzira mbiri: kuzadza pasi pevhu uye kushandisa zviwanikwa.Maitiro echinyakare anozadza migodhi yegoridhe kuzadza mbiru dzakakora mugomba, ukuwo machira akakwenenzverwa anotutirwa mudziva remaswe.Nekuti zviri mukati megoridhe. ore inowanzove yakaderera, kuitira kuti kuwedzere kutorwa kwegoridhe zviwanikwa, zvinowanzodikanwa kuita mabasa ekukuya. Naizvozvo, iyo yakatsetseka-yakaomeswa tailings ine yakawanda, nepo coarse-grained tailings iri shoma, uye chete coarse-grained tailings inozadzwa pasi pevhu. , hazvibviri kuderedza zvakanyanya marara akaomarara uye kuderedza simba rekuchengetedza remasailing madziva. Madziva ekuchengeta miswe achiri kuda ivhu rakawanda uye kunokuvadza zvakatipoteredza. Kuraswa kwemiswe yegoridhe kwave chinhu chikuru chiri kumisa kusimukira kwehupfumi hwemigodhi yegoridhe.
Musi waKukadzi 10, 2022, Bazi reIndasitiri neRuzivo rweTekinoroji, National Development and Reform Commission, Bazi reSainzi neTekinoroji, Bazi reMari, Bazi reZviwanikwa, Ministry of Ecology uye Environment, Ministry of Commerce. , uye State Administration of Taxation yakabatana yakapa "Pakudhinda uye Kugovera Kukurumidzira Kukurudzira kweIndasitiri Zviwanikwa". "Chiziviso pamusoro peImplementation Plan for Comprehensive Utilization" inoda kuti panosvika gore ra2025, kusimba kwekugadzirwa kwemarara akasimba mumaindasitiri akakosha akadai sesimbi nesimbi, simbi dzisina ferrous, uye maindasitiri emakemikari munyika mangu kuchadzikira, huwandu hwekushandisa hwakazara. yemarara akasimba emumaindasitiri achavandudzwa zvakanyanya, indasitiri yezvezviwanikwa icharamba ichikura zvine hutano, uye zviwanikwa zvemaindasitiri zvichashandiswa zvizere. Kushanda zvakanaka kwakavandudzwa zvikuru, uye mwero wakadzama wekushandiswa kwemarara akawanda emumaindasitiri uchasvika pa57%.
Iyo Sino-German Kiyi Laboratory yeMagnetoelectricity uye Intelligent Mineral Processing yeHuate Kambani inoitisa huwandu hukuru hwekuedza kubatsiridza pamatehwe egoridhe munzvimbo yeYantai. Iyo huru yemaminerari ezvikamu zvegoridhe tailings ndeye gangue zvicherwa zvakaita sequartz, feldspar uye calcite, uye shoma shoma yemuchina 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 shoma shoma yemadhaka. Hunhu husina kuchena hweFe2O3 ndeye 1-3%, TiO2 yemukati ndeye 0.1-0.3%, CaO yemukati i0.12-1.0%, uye kuchena kwemasara egoridhe i5-20%. Kune 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, 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, vertical mhete yakakwira gradient magineti separator, uye electromagnetic slurry magineti separator inoshandiswa mukubatana. Ndichiri kuwana yemhando yepamusoro feldspar inonangana kubva kumaswe, zvigadzirwa zvakakosha semagineti, zvicherwa zvine goridhe, simende mbishi, uye zvigadzirwa zvekugadzira zvidhinha zvinodzoserwa zvakare kuti zvione kushandiswa kwakadzama kwemasara egoridhe uye kuwana zero kuburitswa mune zvese. - nzira yekutenderera.
Vertical mhete yakakwira gradient magineti separator uye electromagnetic slurry yakakwira gradient magineti separator inoshandiswa mukugadzira machira egoridhe chirongwa.
