Menene flotation?

Flotation, wanda kuma aka sani da flotation na kumfa ko flotation na ma'adinai, wata dabara ce ta beneficiation wadda ke raba ma'adanai masu mahimmanci daga ma'adanai masu kama da gangue a mahaɗin gas-liquid-solid ta hanyar amfani da bambance-bambancen da ke cikin halayen saman ma'adanai daban-daban a cikin ma'adinan. Haka kuma ana kiransa da "rabuwar fuska." Duk wani tsari da ke amfani da halayen fuska kai tsaye ko a kaikaice don cimma rabuwar barbashi bisa ga bambance-bambancen halayen saman barbashi na ma'adinai ana kiransa flotation.

Sifofin saman ma'adanai suna nufin halayen zahiri da na sinadarai na barbashi ma'adanai, kamar danshi a saman, cajin saman, nau'ikan haɗin sinadarai, jikewa, da kuma amsawar ƙwayoyin halitta na saman. Barbashi daban-daban na ma'adanai suna nuna wasu bambance-bambance a cikin halayen saman su. Ta hanyar amfani da waɗannan bambance-bambancen da kuma amfani da hulɗar fuska, ana iya cimma rabuwar ma'adanai da haɓaka su. Saboda haka, tsarin shawagi ya ƙunshi haɗin gas-ruwa-solid mai matakai uku.

Ana iya gyara halayen saman ma'adanai ta hanyar wucin gadi don haɓaka bambance-bambance tsakanin ƙwayoyin ma'adinai masu mahimmanci da na gangue, ta haka ne za a sauƙaƙe rabuwarsu. A cikin shawagi, galibi ana amfani da reagents don canza halayen saman ma'adanai, ƙara yawan bambancin halayen saman su da kuma daidaita ko sarrafa su. Wannan magudi yana daidaita halayen shawagi na ma'adanai don cimma sakamako mafi kyau na rabuwa. Saboda haka, aikace-aikacen da haɓaka fasahar shawagi suna da alaƙa sosai da haɓaka reagents na shawagi.

Ba kamar yawan abu ko kuma saurin kamuwa da maganadisu ba—halayen ma'adinai waɗanda suka fi wahalar canzawa—gabaɗaya ana iya daidaita halayen saman barbashi na ma'adanai ta hanyar wucin gadi don ƙirƙirar bambance-bambancen da ake buƙata tsakanin ma'adanai don rabuwa mai inganci. Sakamakon haka, ana amfani da flotation sosai a cikin beneficiation na ma'adanai kuma galibi ana ɗaukarsa a matsayin hanyar beneficiation ta duniya baki ɗaya. Yana da tasiri musamman kuma ana amfani da shi sosai don raba kayan da suka fi kyau da waɗanda ba su da kyau.
