Ilitye lePhosphate libhekisa kwigama eliqhelekileyo leeminerali zephosphate ezinokuthi zisetyenziswe ngokwezoqoqosho, ikakhulu i-apatite kunye ne-phosphate rock. Iphosphoric etyheli, iphosphoric acid, iphosfide kunye nezinye iiphosphates zisetyenziswa kwezonyango, ukutya, imatshisi, idayi, iswekile, iiseramikhi, ukhuselo lwelizwe kunye namanye amashishini.
Iipropati zentsimbi kunye noLwakhiwo lweziMbiwa
Kukho malunga ne-120 iintlobo zeeminerali ezine-phosphorus ezaziwa kwindalo, kodwa njenge-phosphorus-equlathe iiminerali zamashishini ubukhulu becala ziyiminerali ye-phosphate kwi-apatite kunye ne-phosphate rock. I-Apatite [Ca5(PO4)3(OH,F)] yiminerali eyona nxalenye yayo iphambili yicalcium phosphate. Inamagama ahlukeneyo ngenxa yezinto ezahlukeneyo eziquletheyo, ezifana ne-fluorine kunye ne-chlorine. Amaminerali aqhelekileyo aqukethe i-phosphorus: I-Fluorapatite, i-chloroapatite, i-hydroxyapatite, i-carbonapatite, i-fluorocarbon apatite, i-carbon hydroxyapatite, njl. Umxholo wethiyori we-P2O5 uphakathi kwe-40.91 kunye ne-42.41%. I-anion eyongezelelweyo F, OH, CO3, kunye ne-O kwilitye le-phosphate inokuthatha indawo enye kwenye, kwaye kukho amacandelo amaninzi e-isomorphic, ngoko ukubunjwa kweekhemikhali zeminerali zitshintsha kakhulu.
Ukwakhiwa kweekhemikhali eziqhelekileyo ze-apatite
- Amacandelo amachiza 2.UmxholoIindawo zesicelo kunye neemfuno zesalathisoIlitye lePhosphate lisetyenziswa ikakhulu njengesichumiso se-asidi ye-phosphoric kunye neekhompawundi ezahlukeneyo ze-phosphorus, kwaye isetyenziswa kakhulu kwiinkalo zoshishino lwemichiza, amayeza, i-pesticide, imboni yokukhanya kunye neshishini lomkhosi.ITekhnoloji yoLungisoUkuxhamla kunye nokuhlanjululwa
Ilitye lePhosphate linokwahlulwa libe luhlobo lwe-siliceous, uhlobo lwe-calcareous, kunye ne-silicon (calcium) -i-calcium (i-silicon) uhlobo. Iiminerali ezihambelanayo ikakhulu ziyi-quartz, i-flint, i-opal, i-calcite, i-feldspar, i-mica, i-limestone, i-dolomite, umhlaba onqabileyo. , imagnetite, iilmenite, i-limonite, njl. njl., indlela yokudada yeyona ndlela ibalulekileyo ye-apatite.
Inkqubo yethekhnoloji yomgaqo ikakhulu ibandakanya: ukudada + ukwahlula kwamagnetic inkqubo edityanisiweyo, ukucola + ukuhlelwa + inkqubo yokudada, inkqubo yokugaya inqanaba + inkqubo yokwahlula inqanaba, ukuqhotsa + ukugaywa + inkqubo yokwahlulahlula.
I-oyile-amanzi adityanisiweyo okupholisa umsesane othe nkqo kwisahluli sothambiso oluphezulu lwemagnethi
Ukwenziwa kweeNdibaniselwano zePhosphate zezichumiso zePhosphate
Ukwenziwa kwezichumiso zePhosphate kukuguqula iiminerali zephosphate zibe yiphosphates ezifunxwa lula zizityalo ngenkqubo yokuzuza, ubushushu obuphezulu, kunye nokudibanisa. I-Ammonium phosphate sisichumiso esisebenza ngokuphezulu sekhompawundi esenziwe ngeasidi yephosphoric kumanzi ammonia. Iphosphorus emthubi ifunyanwa ngokufudumeza ilitye lephosphate elixutywe nesanti yequartz kunye necoke kwi-1500°C kwiziko lombane. Kukho iindlela ezimbini zokuvelisa i-asidi ye-phosphoric: indlela ye-sulfuric acid extraction kunye ne-peroxy combustion absorption method.
Umzekelo wokuxhamla
I-fineness of iron tailings e-Hebei yi-200 mesh, ibalwa kwi-63.29%, umxholo we-iron TFe uphelele ngu-6.95%, kunye nomxholo we-P2O5 ngu-6.89%. Intsimbi ikakhulu i-iron oxide efana ne-limonite, i-iron silicate kunye ne-magnetite ngendlela yokufakwa okuqhubekayo; amaminerali aqukethe i-phosphorus ikakhulu i-apatite, i-ganggue minerals yi-quartz, i-feldspar, i-calcite, njl. Idibaniswe ngokusondeleyo kunye neeminerali ze-phosphorus. Injongo yovavanyo kukukhetha amaminerali ahlukeneyo anentsimbi ngokuhlukana kwamagnetic, kwaye i-apatite ityetyiswe kwi-tailings yokwahlukana kwamagnetic.
Ngokutsho kweempawu zeesampuli, inkqubo yokuzuza inqunywe ngolu hlobo lulandelayo: i-ore ekhethiweyo ekhethiweyo - i-200 mesh ene-fineness ye-63.29%, yenziwe i-slurry ene-concentration ye-30%, kwaye i-iron magnetic eqhubekayo ikhethiwe. nge-CTB4000GS intsimi yamagnetic ebuthathaka, kwaye i-tailings ikhethwe yi-ring ring 0.5T ebuthakathaka i-Magnetic iron oxide kunye ne-iron silicate minerals.
Inkqubo yokuhamba kovavanyo lokususa intsimbi yokwahlula kumagnethi yeentsalela zentsimbi ezinephosphorus
I-iron-containing iron phosphorus tailings iye yafumana inkqubo yokususa isinyithi enye i-roughing kunye neyokutshayela kabini, kunye neemveliso ze-iron concentrate azikwazanga ukukhethwa kwizinto eziphathekayo. Isiqulatho se-phosphorus kwi-coarse concentrate yonyuswe ukusuka kwi-6.89% ukuya kwi-10.12%, kwaye izinga lokubuyiswa kwe-phosphorus libe ngama-79.54%. %, izinga lokususa intsimbi lalingama-75.83%. Kuvavanyo lokuthelekisa amandla ahlukeneyo entsimi ye-Lihuan 0.4T, 0.6T kunye ne-0.8T, kwafunyaniswa ukuba amandla aphantsi e-Lihuan 0.4T abangele intsimbi eninzi kwi-phosphorus coarse kwaye ihlanjululwe, kunye namandla aphezulu e-0.8 I-T ibangele ukulahleka kwe-phosphorus kwizinto eziphathekayo zamagnetic. Enkulu. Ukukhethwa kweemeko ezifanelekileyo zokwahlukana kwamagnetic kunenzuzo ekuphuculeni i-beneficiation index ye-flotation operation yelitye eliphantsi le-phosphate.
