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 Mineral

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 ndi 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.

    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.

    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 wopangidwa bwino 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

    Ubwino wazitsulo zachitsulo ku Hebei ndi -200 mesh, zomwe zimawerengera 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 mawonekedwe a zitsanzo, njira yopezera phindu imatsimikiziridwa motere: ore yaiwisi osankhidwa - 200 mesh ndi fineness ya 63.29%, amapangidwa 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 chachitsulo chimodzi ndi kusesa kawiri, ndipo mankhwala oyenerera achitsulo sangathe 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 molimba 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.
