Kodi flotation ndi chiyani?

Kuyandama, komwe kumadziwikanso kuti froth flotation kapena mineral flotation, ndi njira yopangira ubwino yomwe imalekanitsa mchere wamtengo wapatali ndi gangue minerals pamalo olumikizirana ndi gasi-liquid-solid pogwiritsa ntchito kusiyana kwa mawonekedwe a pamwamba pa mchere wosiyanasiyana mu miyala. Kumatchedwanso "kulekanitsa pakati pa zinthu." Njira iliyonse yomwe imagwiritsa ntchito mwachindunji kapena mwanjira ina mawonekedwe a pakati pa zinthu kuti ikwaniritse kulekanitsa tinthu kutengera kusiyana kwa mawonekedwe a pamwamba pa tinthu ta mchere imatchedwa flotation.

Makhalidwe a pamwamba pa mchere amatanthauza makhalidwe enieni ndi a mankhwala a tinthu ta mchere, monga kunyowa pamwamba, mphamvu ya pamwamba, mitundu ya ma bond a mankhwala, kukhuta, ndi kuyanjana kwa maatomu pamwamba. Tinthu ta mchere tosiyanasiyana timawonetsa kusiyana kwina kwa makhalidwe awo pamwamba. Pogwiritsa ntchito kusiyana kumeneku ndikugwiritsa ntchito kuyanjana kwa pakati pa zinthu, kulekanitsa ndi kuwonjezera mchere kumatha kuchitika. Chifukwa chake, njira yoyandama imaphatikizapo mawonekedwe atatu a gasi-madzimadzi-olimba.

Kapangidwe ka pamwamba pa mchere kangasinthidwe mwaluso kuti pakhale kusiyana pakati pa tinthu tamtengo wapatali ndi ta gangue, zomwe zimathandiza kuti tisiyane. Poyandama, ma reagent nthawi zambiri amagwiritsidwa ntchito kusintha mawonekedwe a pamwamba pa mchere, kukulitsa kusiyana kwa mawonekedwe awo pamwamba ndikusintha kapena kuwongolera kuopsa kwawo kwa madzi. Kusintha kumeneku kumawongolera momwe mchere umayendera kuti upeze zotsatira zabwino zolekanitsa. Chifukwa chake, kugwiritsa ntchito ndi kupititsa patsogolo ukadaulo wa flotation kumalumikizidwa kwambiri ndi chitukuko cha ma flotation reagents.

Mosiyana ndi kuchuluka kwa zinthu kapena mphamvu ya maginito—makhalidwe a mchere omwe ndi ovuta kusintha—makhalidwe a pamwamba pa tinthu ta mchere nthawi zambiri amatha kusinthidwa mwaluso kuti apange kusiyana kofunikira pakati pa mchere kuti pakhale kulekanitsa koyenera. Chifukwa chake, kuyandama kumagwiritsidwa ntchito kwambiri pakuwonjezera mchere ndipo nthawi zambiri kumaonedwa ngati njira yopindulitsa padziko lonse lapansi. Ndi yothandiza kwambiri komanso imagwiritsidwa ntchito kwambiri pakulekanitsa zinthu zabwino ndi zazing'ono kwambiri.
