Thanthwe la Phosphate limatanthawuza mawu ambiri a mchere wa phosphate omwe angagwiritsidwe ntchito pachuma, makamaka mwala wa apatite ndi phosphate.Yellow phosphorous, asidi phosphoric, phosphide ndi phosphates zina ntchito mankhwala, chakudya, machesi, utoto, shuga, ziwiya zadothi, chitetezo dziko ndi minda ina mafakitale.
Katundu wa Ore ndi Kapangidwe ka Mchere
Pali mitundu pafupifupi 120 ya mchere wokhala ndi phosphorous womwe umadziwika m'chilengedwe, koma monga mchere wam'mafakitale wokhala ndi phosphorous ndi mchere wa phosphate mu apatite ndi thanthwe la phosphate.Apatite [Ca5(PO4)3(OH,F)] ndi mchere womwe chigawo chake chachikulu ndi calcium phosphate.Lili ndi mayina osiyanasiyana chifukwa cha zinthu zosiyanasiyana zomwe zili nazo, monga fluorine ndi chlorine.Common phosphorous munali mchere ndi: Fluorapatite, chloroapatite, hydroxyapatite, carbonapatite, fluorocarbon apatite, mpweya hydroxyapatite, etc. The ongolankhula zili P2O5 pakati 40.91 ndi 42.41%.Ma anions owonjezera F, OH, CO3, ndi O mu thanthwe la phosphate amatha kusinthana wina ndi mzake, ndipo pali zigawo zambiri za isomorphic, kotero kuti mankhwala a mchere amasintha kwambiri.
Chitsanzo mankhwala zikuchokera apatite
- Zigawo za Chemical 2.ContentMalo ogwiritsira ntchito ndi zofunikira za indexPhosphate thanthwe zimagwiritsa ntchito monga zopangira phosphoric asidi fetereza ndi mankhwala osiyanasiyana phosphorous, ndipo chimagwiritsidwa ntchito m'mafakitale mankhwala makampani, mankhwala, mankhwala, makampani kuwala ndi makampani asilikali.Processing TechnologyKupindula ndi kuyeretsedwa
Thanthwe la phosphate likhoza kugawidwa mumtundu wa siliceous, mtundu wa calcareous, ndi silicon (calcium) -calcium (silicon) mtundu.Michere yogwirizana ndi quartz, mwala, opal, calcite, feldspar, mica, miyala yamchere, dolomite, dziko lapansi losowa., magnetite, ilmenite, limonite, etc., njira yoyandama ndiyo njira yofunika kwambiri yopezera apatite.
Mfundo zamakono ndondomeko makamaka zikuphatikizapo: flotation + maginito kupatukana ophatikizana ndondomeko, akupera + gulu + flotation ndondomeko, siteji akupera + siteji kulekana ndondomeko, Kuwotcha + chimbudzi + gulu ndondomeko.
Mafuta okhala ndi madzi ophatikizika kuzirala kwa mphete yowongoka, chophatikizira cha maginito olekanitsa
Kukonza Zosakaniza za Phosphate za Feteleza wa Phosphate
Kupanga feteleza wa phosphate ndikutembenuza mchere wa phosphate kukhala ma phosphates omwe amatengedwa mosavuta ndi zomera kudzera munjira ya beficiation, kutentha kwambiri, ndi kaphatikizidwe.Ammonium phosphate ndi feteleza wothandiza kwambiri wopangidwa kuchokera ku phosphoric acid m'madzi ammonia.Phosphorous yachikasu imapezeka potenthetsa mwala wa phosphate wosakanikirana ndi mchenga wa quartz ndi coke pa 1500 ° C mung'anjo yamagetsi.Pali njira ziwiri zopangira phosphoric acid: njira yotulutsa sulfuric acid ndi njira yoyatsira peroxy.
Chitsanzo cha Beneficiation
Kuwongolera kwachitsulo ku Hebei ndi -200 mesh, kuwerengera 63.29%, zonse zachitsulo TFe zili 6.95%, ndi P2O5 ndi 6.89%.Chitsulo makamaka chitsulo okusayidi monga limonite, chitsulo silicate ndi magnetite mu mawonekedwe a inclusions mosalekeza;phosphorous munali mchere makamaka apatite, gangue mchere ndi quartz, feldspar, calcite, etc. Iwo ali kwambiri pamodzi ndi phosphorous mchere.Cholinga cha mayesowa ndikusankha mchere wosiyanasiyana wokhala ndi chitsulo ndi kupatukana kwa maginito, ndipo apatite amalemeretsedwa ndi maginito olekanitsa maginito.
Malinga ndi katundu wa zitsanzo, ndondomeko ya beneficiation imatsimikiziridwa motere: ore yaiwisi yosankhidwa - 200 mesh ndi fineness ya 63.29%, imapangidwa kukhala slurry ndi ndende ya 30%, ndipo chitsulo chosalekeza chimasankhidwa. ndi CTB4000GS ofooka maginito, ndi michira amasankhidwa ndi ofukula mphete 0.5T ofooka Magnetic chitsulo okusayidi ndi chitsulo silicate mchere.
Njira otaya maginito kulekana chitsulo kuchotsa mayeso phosphorous munali chitsulo michira
Zitsulo zachitsulo za phosphorous zomwe zili ndi chitsulo zakhala zikugwiritsidwa ntchito pochotsa chitsulo chimodzi chogwedeza ndi kusesa kawiri, ndipo zopangira zitsulo zoyenerera sizikanatha kusankhidwa kuchokera ku maginito.Phosphorous yomwe ili mu phosphorous coarse concentrate inawonjezeka kuchoka pa 6.89% kufika pa 10.12%, ndipo chiwerengero cha kuchira kwa phosphorous chinali 79.54%.%, chitsulo chochotsa chitsulo chinali 75.83%.Poyerekeza mayeso osiyanasiyana amphamvu za Lihuan 0.4T, 0.6T ndi 0.8T, zidapezeka kuti mphamvu yotsika ya Lihuan 0.4T idadzetsa chitsulo chochuluka mu phosphorous mowongoka komanso woyengedwa, komanso kulimba kwamphamvu kwa 0,8 T idayambitsa kutayika kwa phosphorous muzinthu zamaginito.Chachikulu.Kusankhidwa kwa malo oyenera olekanitsa maginito ndikopindulitsa kuwongolera index ya beneficiation ya ntchito yoyandama ya thanthwe lapansi la phosphate.
