Kodi flotation beneficiation ndi chiyani?

Flotation, yomwe imadziwikanso kuti froth flotation, ndi njira yopangira mchere yomwe imalekanitsa mchere wamtengo wapatali kuchokera ku mchere wa gangue pamalo owoneka bwino a gasi-liquid-solid potengera kusiyana kwapamtunda wa mchere wosiyanasiyana. Imatchedwanso "interface separation". Njira iliyonse yomwe imagwiritsa ntchito molunjika kapena mosagwirizana ndi magawo olumikizirana kuti alekanitse tinthu tating'ono ta mchere kutengera kusiyana kwa mawonekedwe awo, imatchedwa flotation.

Mamineral surface properties amatanthawuza mawonekedwe a thupi ndi mankhwala a mineral particle, monga kunyowa pamwamba, mphamvu zamagetsi zapamwamba, mitundu ya ma bondi a mankhwala pamtunda wa maatomu, machulukitsidwe, ndi reactivity. Tinthu ta michere yosiyanasiyana ikuwonetsa malo osiyana, ndipo mwa kukulitsa kusiyana kumeneku pogwiritsa ntchito mawonekedwe a magawo, kulekanitsidwa michere ndi zolemetsa zitha kutheka. Chifukwa chake, kuyandama kumaphatikizapo kuyanjana kwa gasi, madzi, ndi magawo olimba pamawonekedwe.

Ma mineral surface amatha kusinthidwa kudzera mukuchitapo kanthu kochita kupanga kuti akweze kusiyana pakati pa mchere wamtengo wapatali ndi mchere wa gangue, potero kuthandizira kulekanitsa kwawo. Poyandama, ma reagents oyandama amagwiritsidwa ntchito kwambiri kusinthira zinthu zamchere pamwamba, kukulitsa kusiyana pakati pa mchere, ndikuwonjezera kapena kuchepetsa hydrophobicity ya malo amchere. Izi zimathandiza kusintha ndi kuwongolera khalidwe la mineral flotation kuti akwaniritse zotsatira zolekanitsa bwino. Chifukwa chake, kugwiritsa ntchito ndi kukonza ukadaulo wa flotation kumalumikizidwa kwambiri ndi kugwiritsa ntchito ma reagents oyandama.

Mosiyana ndi mawonekedwe a thupi monga kachulukidwe ndi maginito amphamvu, omwe ndi ovuta kusintha, mawonekedwe a pamwamba a mineral particles akhoza kusinthidwa mosavuta kupyolera mwa kulowererapo kwa anthu kuti apange kusiyana komwe kumakwaniritsa zofunikira zolekanitsa. Zotsatira zake, kuyandama kumagwiritsidwa ntchito kwambiri pakulekanitsa mchere ndipo nthawi zambiri kumatchedwa "universal mineral processing method." Ndiwothandiza kwambiri komanso amagwiritsidwa ntchito kwambiri pakulekanitsa tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono tomwe timagwiritsidwa ntchito popanga mchere.
