Nyob rau xyoo nees nkaum thawj, cov tuam txhab loj nrog cov nroj tsuag loj tsis tu ncua ua haujlwm cais cov hlau los ntawm cov txheej txheem flotation. Keeb kwm ntawm cov txheej txheem flotation pib nyob rau hauv xyoo pua 19, tab sis flotation yog suav tias yog qhov tseem ceeb tshaj plaws kev tsim kho ntawm lub xyoo pua nees nkaum mining thiab milling kev lag luam.
Thaum twg flotation invented?
Inventor Hezekiah Bradford ntawm Philadelphia tau tsim ib "txoj kev ntawm kev txuag cov khoom ntab hauv cov khoom sib cais" thiab tau txais US patent No.
txoj kev flotation siv nyob qhov twg?
Flotation yog siv dav rau ntseeg tooj liab, lead, thiab zinc minerals, uas feem ntau nrog ib leeg hauv lawv cov ores. Ntau cov ore sib xyaw ua ke yav dhau los ntawm tus nqi me me tau dhau los ua qhov loj ntawm qee cov hlau los ntawm txoj kev flotation.
Vim li cas cov txheej txheem flotation tseem ceeb?
Froth flotation yog tseem ceeb concentration txheej txheem uas xaiv cais cov khoom muaj txiaj ntsig hydrophobic los ntawm hydrophilic khib gangue. … Kev sib cais – Cov pob zeb hauv av tau muab cais tawm ntawm cov dej da dej thiab cov txiaj ntsig tau ua kom zoo ntxiv kom xa cov pob zeb xav tau lossis hlau.
froth flotation siv rau dab tsi?
