Kodi flotation beneficiation ndi chiyani?

Kuyandama, komwe kumadziwikanso kuti froth flotation, ndi njira yopangira mchere yomwe imalekanitsa mchere wamtengo wapatali ndi mchere wa gangue pa gas-liquid-solid interface pogwiritsa ntchito kusiyana kwa mawonekedwe a pamwamba pa mchere wosiyanasiyana. Kumatchedwanso "kulekanitsa pakati pa mitundu." Njira iliyonse yomwe imagwiritsa ntchito mwachindunji kapena mwanjira ina ma phase interfaces kulekanitsa tinthu ta mchere kutengera kusiyana kwa mawonekedwe awo a pakati pa mitundu imatchedwa flotation.

Makhalidwe a pamwamba pa mchere amatanthauza makhalidwe enieni ndi a mankhwala a pamwamba pa tinthu ta mchere, monga kunyowa pamwamba, makhalidwe amagetsi pamwamba, mitundu ya ma bond a mankhwala pa maatomu pamwamba, kukhuta, ndi reactivity. Tinthu ta mchere tosiyanasiyana timasonyeza makhalidwe osiyana pamwamba, ndipo pogwiritsa ntchito kusiyana kumeneku pogwiritsa ntchito ma phase interfaces, kulekanitsa ndi kuwonjezera mchere kumatha kuchitika. Chifukwa chake, njira yoyandama imaphatikizapo kuyanjana kwa magawo a mpweya, madzi, ndi olimba pamalo olumikizirana.

Kapangidwe ka mchere pamwamba pake kangasinthidwe kudzera mu njira yopangira zinthu kuti ziwonjezere kusiyana pakati pa mchere wamtengo wapatali ndi mchere wa gangue, motero zimathandiza kulekanitsa kwawo. Pa kuyandama, zinthu zoyatsira madzi zimagwiritsidwa ntchito nthawi zambiri kusintha zinthu za mchere pamwamba pake, kuwonjezera kusiyana pakati pa mchere, ndikuwonjezera kapena kuchepetsa kusagwirizana kwa madzi pamwamba pa mchere. Izi zimathandiza kusintha ndi kuwongolera khalidwe la kuyandama kwa mchere kuti pakhale zotsatira zabwino zolekanitsa. Chifukwa chake, kugwiritsa ntchito ndi kupanga ukadaulo wa kuyandama kumagwirizana kwambiri ndi kugwiritsa ntchito zinthu zoyatsira madzi.

Mosiyana ndi magawo enieni monga kuchulukana ndi mphamvu ya maginito, zomwe zimakhala zovuta kusintha, mawonekedwe a pamwamba pa tinthu ta mchere amatha kusinthidwa mosavuta kudzera mwa anthu kuti apange kusiyana komwe kumakwaniritsa zofunikira pakulekanitsa. Chifukwa chake, kuyandama kumagwiritsidwa ntchito kwambiri pakulekanitsa mchere ndipo nthawi zambiri kumatchedwa "njira yopangira mchere padziko lonse lapansi." Ndi yothandiza kwambiri komanso imagwiritsidwa ntchito kwambiri pakulekanitsa tinthu tating'onoting'ono ndi tating'ono kwambiri, zomwe zimapangitsa kuti ikhale imodzi mwa njira zogwiritsidwa ntchito kwambiri komanso zogwira mtima pakukonza mchere.
