Dombo rephosphate rinoreva izwi rekuti phosphate minerals rinogona kushandiswa nehupfumi, kunyanya apatite ne phosphate rock. Yellow phosphorus, phosphoric acid, phosphide nedzimwe phosphates dzinoshandiswa mukurapa, chikafu, machisi, dhayi, shuga, ceramics, kudzivirira nyika nedzimwe nzvimbo dzeindasitiri.
Zvivakwa zveMatombo neMaumbirwo eMineral
Kune mhando dzinosvika zana nemakumi maviri dzezvicherwa zvine phosphorus dzinozivikanwa muzvisikwa, asi sezvicherwa zveindasitiri zvine phosphorus, zvinonyanya kuve zvicherwa zve phosphate mu apatite ne phosphate rock. Apatite [Ca5(PO4)3(OH,F)] imineral ine chikamu chikuru chiri calcium phosphate. Ine mazita akasiyana nekuda kwezvinhu zvakasiyana zvirimo, zvakaita se fluorine ne chlorine. Zvicherwa zvine phosphorus zvakajairika ndeizvi: Fluorapatite, chloroapatite, hydroxyapatite, carbonapatite, fluorocarbon apatite, carbon hydroxyapatite, nezvimwewo. Zviri mukati meP2O5 zviri pakati pe40.91 ne42.41%. Ma anions ekuwedzera F, OH, CO3, uye O mu phosphate rock anogona kutsivana, uye kune zvakawanda zvikamu zve isomorphic, saka makemikari e mineral anochinja zvakanyanya.

Dombo rephosphate rinogona kukamurwa kuita mhando ye siliceous, mhando ye calcareous, uye mhando ye silicon (calcium)-calcium (silicon). Zvicherwa zvine chekuita nazvo zvinonyanya kuve quartz, flint, opal, calcite, feldspar, mica, limestone, dolomite, rare earth. , magnetite, ilmenite, limonite, nezvimwewo, flotation method ndiyo nzira inonyanya kukosha yekubatsira apatite.
Maitiro makuru ehunyanzvi anosanganisira: kupatsanurwa kwemvura + kupatsanurwa kwemagineti, kupwanya + kupatsanurwa + kupwanya kwemvura, kupwanya kwechikamu + kupatsanurwa kwechikamu, kugocha + kugaya + kupatsanurwa kwechikamu.

Ammonium phosphate ifetiraiza inogadzirwa nephosphoric acid mumvura yeammonia. Yero phosphorus inowanikwa nekupisa dombo rephosphate rakasanganiswa nejecha requartz necoke pa1500°C muchoto chemagetsi. Kune nzira mbiri dzekugadzira phosphoric acid: nzira yekubvisa sulfuric acid uye nzira yekupisa peroxy.

Iron inonyanya kushandiswa se iron oxide senge limonite, iron silicate uye magnetite muchimiro che continuous inclusions; minerals dzine phosphorus dzinonyanya kushandiswa se apatite, gangue minerals i quartz, feldspar, calcite, nezvimwewo. Inonyanya kushandiswa pamwe chete ne phosphorus minerals. Chinangwa chebvunzo ndechekusarudza minerals dzakasiyana-siyana dzine simbi nekupatsanurwa kwemagnetic, uye apatite inowedzerwa ne magnetic separation tailings.
Zvichienderana nehunyanzvi hwemasampuli, maitiro ekugadzira anotsanangurwa seizvi: dombo rakasarudzwa - 200 mesh ine hunyoro hwe63.29%, inogadzirwa kuita slurry ine huwandu hwe30%, uye simbi inoramba ichishandiswa inosarudzwa neCTB4000GS weak magnetic field, uye tailings inosarudzwa ne vertical ring 0.5T weak Magnetic iron oxide uye iron silicate minerals.
