Kev Siv Tshuab Ua Haujlwm
Kev Pab thiab Kev Ua Kom Huv Si
Cov zaub mov uas sib xyaw nrog fluorite yog: quartz, calcite, scheelite, apatite, cassiterite, wolframite, pyrite, sphalerite, lapis lazuli, muscovite, galena, chalcopyrite, rhodochrosite Manganese ore, dolomite, potassium feldspar, spinel, barite, thiab lwm yam. Raws li qhov sib txawv ntawm cov khoom ntawm cov zaub mov cuam tshuam hauv fluorite, kev sib cais thiab kev ntxuav yog ua los ntawm kev ntab, kev sib cais sib nqus, kev sib cais lub ntiajteb txawj nqus thiab lwm txoj kev pab.
①Kev Ua Dej
Kev ua kom cov fluorite zoo yog txoj hauv kev tseem ceeb tshaj plaws los ua kom cov roj fluorite zoo. Cov txheej txheem dav dav yog sau cov roj fatty acids tom qab sib tsoo, thiab xaiv cov khoom fluorite concentrate tsim nyog los ntawm ntau txoj kev xaiv; rau cov minerals sulfide cuam tshuam, cov tshuaj daj raug xaiv, thiab cov barite, calcite, muscovite, thiab lwm yam cuam tshuam raug sib cais los ntawm cov inhibitors.
②Kev xaiv dua tshiab - kev ntab dej
Thaum cov ore qib qis lossis muaj ntau lub cev sib xyaw ua ke, cov txheej txheem ua ke ntawm kev sib cais ntawm lub ntiajteb txawj nqus thiab kev ntab feem ntau yog siv.
