Phosphate kev npaj cov kev npaj feem ntau yog muab faib ua peb txoj kev txheej txheem: thermal, ntub, thiab electrochemical.
Cov txheej txheem thermal, uas cuam tshuam cov cua sov phosphoric acid, yog lub zog {{caum kwh ib tuj) thiab yog feem ntau siv hauv daj phosphorus ntau lawm. Tam sim no, tsuas yog qee cov tuam txhab hauv Tebchaws Europe thiab Asmeskas tuav cov kab ntau lawm.
Cov txheej txheem ntub dej, tswj hwm los ntawm cov sulfuric acid txuj ci (suav rau 80% ntawm cov pob zeb ntau lawm), muaj kua qaub cov pob zeb ntau lawm), muab qhov kom zoo dua ntawm kev tsim khoom txuas ntxiv. Ua kom tiav tus nqi defluorination ntawm ntau tshaj 95% tso siab rau txoj kev tswj hwm kub (800} 950 degree) thiab phosphoric acid piv. Cov thev naus laus zis tseem ceeb rau kev ua tiav cov phiaj xwm phosphorus tau tshaj li 85% tau tsim los ntawm Sichuan Longmang tau raug ncua vim tias qhov kev thov tsawg heev rau High-qib phosphate pob zeb.
Cov txheej txheem electrochemical, uas muaj feem cuam tshuam txog electrolying phosphoric acid thiab hydrochloric acid, tam sim no muaj kev txwv nyob rau hauv kev siv cov ntawv thov. Tuam Tshoj tau ua cov kev sib tawg hauv thev naus laus zis rau kev npaj cov khoom siv microparticle, nce ib qho {}}}} {rau 500,000 tons, uas tau hloov cov khoom lag luam.
