Flotation ni iki?

Flotation, izwi kandi nka floth flotation cyangwa minerval flotation, ni tekinike yunguka itandukanya amabuye y'agaciro namabuye y'agaciro ya gangue kuri gazi-yamazi-akomeye hifashishijwe itandukaniro riri mumiterere yubutaka bwamabuye y'agaciro atandukanye. Yitwa kandi "gutandukana hagati." Inzira iyo ari yo yose ikoresha mu buryo butaziguye cyangwa butaziguye imikoreshereze y’imiterere kugira ngo igere ku gutandukanya ibice bishingiye ku itandukaniro riri hagati y’imiterere y’imiterere y’imyunyu ngugu yitwa flotation.

Imiterere yubutaka bwamabuye y'agaciro bivuga ibiranga umubiri na chimique biranga imyunyu ngugu, nko guhindagurika kwubutaka, kwishyurwa hejuru, ubwoko bwimiti ya chimique, kwiyuzuzamo, hamwe nubushobozi bwa atome yo hejuru. Ibice bitandukanye byamabuye y'agaciro byerekana itandukaniro ryimiterere yabyo. Mugukoresha itandukaniro no gukoresha imikoranire hagati, gutandukanya amabuye y'agaciro no gukungahaza birashobora kugerwaho. Kubwibyo, inzira ya flotation ikubiyemo gaze-yamazi-ikomeye-ibice bitatu.

Imiterere yubutaka bwamabuye y'agaciro irashobora guhindurwa muburyo bwogukora kugirango hongerwe itandukaniro riri hagati yimyunyu ngugu ifite agaciro na gangue, bityo byoroshye gutandukana. Muri flotation, reagent ikoreshwa muguhindura imiterere yubutaka bwamabuye y'agaciro, ikongerera itandukaniro mubiranga ubuso bwabo no guhindura cyangwa kugenzura hydrophobicity. Iyi manipulation igenga imyitwarire ya flotation yamabuye y'agaciro kugirango igere kubisubizo byiza byo gutandukana. Kubwibyo, gukoresha no guteza imbere tekinoroji ya flotation bifitanye isano rya bugufi niterambere ryimiterere ya flotation.

Bitandukanye n'ubucucike cyangwa magnetiki byoroshye - imiterere yubutare bigoye guhinduka - imiterere yubuso bwibice byamabuye y'agaciro irashobora guhindurwa muburyo bwubukorikori kugirango habeho itandukaniro rikenewe hagati yimyunyu ngugu kugirango itandukane neza. Kubera iyo mpamvu, flotation ikoreshwa cyane mugutunganya amabuye y'agaciro kandi akenshi ifatwa nkuburyo bwo kugirira akamaro isi yose. Nibyiza cyane kandi bikoreshwa cyane mugutandukanya ibikoresho byiza na ultra-nziza.
