Phosphate rock inoreva izwi rinowanzoreva phosphate minerals inogona kushandiswa mune zvehupfumi, kunyanya apatite uye phosphate rock. Yellow phosphorus, phosphoric acid, phosphide uye mamwe phosphates anoshandiswa mukurapa, chikafu, machisi, dhayi, shuga, ceramics, kudzivirira kwenyika uye mamwe maindasitiri minda.
Ore Properties uye Mineral Structure
Kune marudzi angangosvika zana nemakumi maviri emhando dzemaminerari ane phosphorus anozivikanwa muchisikirwo, asi senge phosphorus-ine maindasitiri zvicherwa zvinonyanya kuita phosphate minerals muapatite uye phosphate rock. Apatite [Ca5(PO4)3(OH,F)] iminerari ine chikamu chikuru icalcium phosphate. Iine mazita akasiyana nekuda kwezvinhu zvakasiyana zvainazvo, senge fluorine uye chlorine. Kazhinji phosphorus-ine maminerari ndeaya: Fluorapatite, chloroapatite, hydroxyapatite, carbonapatite, fluorocarbon apatite, carbon hydroxyapatite, nezvimwewo. Theoretical content yeP2O5 iri pakati pe40.91 ne42.41%. Iyo yekuwedzera anions F, OH, CO3, uye O muphosphate rock inogona kutsiva imwe neimwe, uye kune akawanda isomorphic zvikamu, saka kemikari yemaminerari inoshanduka zvakanyanya.

Phosphate dombo rinogona kukamurwa kuita siliceous mhando, calcareous mhando, uye nesilicon (calcium) -calcium (silicon) mhando. Izvo zvicherwa zvinosanganiswa zvakanyanya quartz, flint, opal, calcite, feldspar, mica, limestone, dolomite, isingawanzo pasi. , magnetite, ilmenite, limonite, nezvimwewo, nzira yekufambisa ndiyo inonyanya kukosha nzira yekubatsira yeapatite.
Iyo musimboti wetekinoroji maitiro anonyanya kusanganisira: flotation + magineti kuparadzaniswa kwakasanganiswa maitiro, kukuya + kupatsanura + flotation process, nhanho yekukuya + nhanho yekuparadzanisa maitiro, kugocha + digestion + classification process.

Kugadziriswa kwePhosphate Compounds yePhosphate Fertilizer
Kugadzira phosphate fetiraiza ndeye kushandura phosphate zvicherwa kuita phosphates inotorwa nyore nyore nezvirimwa kuburikidza nekuita kwebeneficiation, tembiricha yepamusoro, uye synthesis. Ammonium phosphate ndeyepamusoro-inoshanda musanganiswa fetiraiza yakagadzirwa kubva kuphosphoric acid mumvura yeammonia. Yellow phosphorus inowanikwa nekudziisa phosphate rock yakasanganiswa nequartz jecha necoke pa1500°C muchoto chemagetsi. Kune nzira mbiri dzekugadzira phosphoric acid: nzira yekubvisa sulfuric acid uye peroxy combustion absorption nzira.
Beneficiation muenzaniso
Kunaka kwesimbi muHebei ndeye -200 mesh, inoverengera 63.29%, iyo yakazara iron TFe inokwana 6.95%, uye iyo P2O5 yemukati i6.89%. Simbi inonyanya kuita iron oxide yakadai selimonite, iron silicate uye magnetite nenzira yekuenderera mberi inclusions; phosphorus-ine zvicherwa zvinonyanya apatite, gangue minerals ndeye quartz, feldspar, calcite, etc. Inonyanya kusanganiswa ne phosphorus minerals. Chinangwa cheyedzo ndechekusarudza akasiyana simbi-inotakura zvicherwa nekuparadzaniswa kwemagineti, uye apatite inopfumiswa mumagineti yekuparadzanisa tailings.
Zvinoenderana nehunhu hwemasamples, maitiro ekubatsira anotemerwa sezvinotevera: iyo yakasarudzwa yakasvibira ore - 200 mesh ine fineness ye63.29%, inogadzirwa slurry ine huwandu hwe30%, uye inoenderera magineti iron inosarudzwa. neCTB4000GS isina simba remagineti, uye miswe inosarudzwa neinomira mhete 0.5T isina simba Magnetic iron oxide uye iron silicate minerals.
Maitiro ekuyerera kwemagineti yekuparadzanisa simbi yekubvisa bvunzo yephosphorus-ine simbi tailings
Iron-ine phosphorus iron tailings yakaitwa yekubvisa simbi yeimwe roughing uye imwe kutsvaira kaviri, uye akakodzera simbi concentrate zvigadzirwa hazvigone kusarudzwa kubva kune iyo magineti. Iyo phosphorus iri mu phosphorus coarse concentrate yakawedzera kubva pa6.89% kusvika pa10.12%, uye phosphorus recovery rate yaive 79.54%. %, chiyero chekubvisa simbi chaive 75.83%. Mukuenzanisa kwekuenzanisa kwemasimba akasiyana-siyana eLihuan 0.4T, 0.6T uye 0.8T, zvakaonekwa kuti simba remunda rakaderera reLihuan 0.4T rakakonzera simbi yakawandisa mu phosphorus yakaoma uye yakanatswa, uye simba repamusoro re0.8 T yakakonzera kurasikirwa kwephosphorus mune magineti zvinhu. Big. Kusarudzwa kweakakodzera magineti yekuparadzanisa mamiriro anobatsira kuvandudza iyo beneficiation index ye flotation mashandiro eiyo yakaderera phosphate rock.
