Dab tsi yog cov ntsiab lus ntawm mica boards?

Feem ntau ntawm cov tailings yog mica phaj gangue deposits, thiab cov pob zeb hauv av ntawm cov khoom sib cais keng feem ntau yog keng mica, me me ntawm keng muscovite, phosphite thiab ci galaxies. Lwm qhov kev tso nyiaj gangue yog dominated los ntawm albite, ua raws li quartz, potassium feldspar, topaz, sericite, thiab kaolinite.

Cov hlau deposits nyob rau hauv lub mica phaj ore yog ib tug kuj ntxhov, thiab cov hom ntawm deposits complex, nrog rau cov thawj deposits thiab lwm yam oxidized deposits; ob qho tib si oxidized deposits, hydroxides, thiab sulfide deposits. Txawm li cas los xij, cov ntsiab lus ntawm ntau yam minerals yog sparse, tsuav yog Dani mineral deposits tuaj yeem rov ua dua los ntawm cov khoom lag luam. Lwm cov hlau deposits yog magnetite, hematite, danielite, nplua spar, cassiterite, altered dislocation, pyrite, phosphorite, pyrite, chalcopyrite, sphalerite ore, galena, chalcocite, bornite, thiab lwm yam oxidized minerals xws li limonite, tooj liab xiav, thiab lwm yam. 

Vim hais tias cov pob zeb hauv av tau muab los ntawm Danni lub ntiajteb txawj nqus sib cais tailings, cov mica daim hlau tau raug crushed thiab hauv av ua ntej lub ntiajteb txawj nqus sib cais, yog li ntawd ntau cov pob zeb hauv av tau raug puas tsuaj, thiab nws yog ib qho nyuaj rau soj ntsuam tag nrho embedded yam ntxwv. Nrhiav qhov seem. Tom qab kev sib tsoo, cov xuab zeb nyias nyias, ua ke nrog cov yam ntxwv tau pom nyob rau hauv lub tshuab tsom iav ntawm qhov chaw tso nyiaj, cov ncauj lus kom ntxaws raws li hauv qab no: Kengmica (Kengmuscovite): nyob rau hauv daim ntawv teev, nplooj, laminations, tuab daim hlau, tsawg heev nyob rau hauv ib daim hlab. Feem ntau nyob rau hauv cov nplooj tsis zoo, dissociated thiab tsim, thiab hauv qab nto yog heev dissociated, feem ntau nyob rau hauv flakes. mica feem ntau yog txuam nrog albite, ua raws li quartz, potassium feldspar, topaz, kaolinite, thiab sericite. Mica daim hlau txuas nrog albite nyob rau hauv ntau hom, ib co ntawm lawv tau dhau los ntawm lawv tus kheej, thiab qhwv los ntawm kengmica; ib co yog ua ke nrog quartz hais, sericite los yog kaolinite. Albite thiab sericite yog ua tsis tu ncua. Feem ntau, albite feem ntau yog tawg ntawm ntug ntawm sericite. Qee cov albites raug ceeb toom los ntawm kaolinite thiab sericite los tsim ob lossis peb hom minerals ua ke nrog sericite thiab lwm cov gangues. Cov pob zeb hauv av ntawm cov poov tshuaj feldspar thiab quartz feem ntau yog nyob rau saum npoo ntawm mica, thiab ib qho me me ntawm kengmica yog qhwv hauv cov ntxhia hauv sub-minerals xws li danni hlau ore thiab hloov kab mob. Ib qho me me ntawm cov minerals dub qhwv hauv ntom mica, los yog limonite, magnetite, thiab lwm yam, feem ntau yog tawg nyob rau hauv lub dissociation seam ntawm mica.
