Nyob rau hauv kev rho tawm ntawm txhuas, qhov tseem ceeb ntawm leaching yog kom mloog zoo alumina (Al2O3) los ntawm bauxite ore. Bauxite feem ntau muaj silica, hlau oxide, thiab titanium oxide ua impurities.
Qhov tseem ceeb ntawm leaching hauv kev rho tawm cov hlau yog dab tsi?
Yog li, los ntawm cov lus piav qhia saum toj no nws pom tseeb tias leaching hauv cov txheej txheem ntawm kev rho tawm ntawm txhuas yog ua kom tshem tawm cov impurities xws li hlau oxide, silicon dioxide thiab titanium oxide.
Qhov tseem ceeb ntawm leaching hauv kev rho tawm kub yog dab tsi?
Leaching yog txheej txheem ntawm kev rho tawm cov khoom siv soluble los ntawm cov khoom siv los ntawm cov kuab tshuaj [1]. Leaching txheej txheem kuj yog siv dav hauv cov hlau ua kev lag luam thiab yog ib theem tseem ceeb ntawm reactant hauv kub ntau lawm [2]. Feem ntau, kub yog leached los ntawm nws cov ore siv cov aqueous sodium cyanide tov.
YPuas yog txhuas rho tawm los ntawm leaching?
Rau qhov kev rho tawm ntawm txhuas los ntawm alumina uas muaj cov ntxhia, acid leaching txheej txheem feem ntau nyiam. … Txawm li cas los xij, nyob rau hauv cov txheej txheem leaching cov kua qaub, lub fwj tseem ceeb yog kev sib koom ua ke ntawm hlau, potassium, calcium, magnesium thiab sodium.
Cov tshuaj twg yog siv los ntxuav cov ore hauv aluminium rho tawm?
Nyob rau hauv cov txheej txheem Bayer, bauxite ore yog rhuab rau hauv lub nkoj siab nrog rau cov tshuaj sodium hydroxide (caustic soda) ntawm qhov kub ntawm 150 txog 200 ° C. Ntawm cov kub no, cov txhuas yog yaj li sodium aluminate (feem ntau [Al(OH) 4 - ) hauv cov txheej txheem rho tawm.
