Njira ya froth flotation nthawi zambiri imafotokozedwa ngati zochitika zakuthupi, pomwe tinthu tating'ono tating'ono timakopeka, ndikudziphatika pamwamba pa thovu, ndikunyamulidwa pamwamba pa selo, komwe limasefukira mu chotsuka chotayira. , nthawi zambiri mothandizidwa ndi zopalasa, zozungulira komwe kochapira (komwe nthawi zambiri kumakhala khola, komwe cholinga chake ndi kunyamula matopewo kupita ku thanki komwe amakapopedwa kuti apitilize kukonzedwa, monga kuthira madzi kapena kutulutsa. pa makina ochiritsira flotation, ndi mbali ina ya selo ku chakudya, kuonetsetsa slurry kuyenda utali wonse wa selo kudutsa angapo mabanki munali impeller-diffusers, asanatulutsidwe ngati michira.

Mitundu ingapo ya mankhwala imakhudzidwa ndi kuyandama kwa froth, ndipo ena angapo amatha kukhudzidwa.Choyamba ndi promotor kapena frother.Mankhwalawa amangopanga thovu lamphamvu zokwanira kuti lifike pamwamba popanda kusweka.Kukula kwa thovu ndikofunika, komanso, ndipo mayendedwe ake ndi ma thovu ang'onoang'ono, popeza amapereka malo ochulukirapo (kukhudzana ndi zolimba zamchere mwachangu), ndipo amakhala okhazikika.Kenako otolera reagents ndi chachikulu mankhwala amene adzapanga chomangira chapadera mchere pa kuwira pamwamba.Osonkhanitsa amakokera pamwamba pa mchere kapena amapanga mankhwala ndi mchere, kuwalola kuti azikhala ogwirizana ndi kukwera kwa chotsuka.Mowa ndi ma acid ofooka ndi mitundu iwiri yamankhwala otolera omwe amagwiritsidwa ntchito kwambiri pakupindula kwa mineral.

Palinso ma reagents omwe amagwiritsidwa ntchito pang'ono, monga odetsa nkhawa, kuti achepetse mankhwala kuti asagwirizane ndi thovu, mankhwala osintha pH, ndi ma activate agents.Ma activate agents amathandiza osonkhanitsa kuti agwirizane ndi mchere wina womwe ndi wovuta kuyandama.

Makampani monga Cytec, Nalco, ndi Chevron Phillips Chemical Company ndi omwe amapanga mitundu yonse yamankhwala oyandama.

Momwemo, ma reagents adzawonjezedwa ku thanki yowonongeka, ndi agitator, asanapite ku selo yoyandama, koma nthawi zambiri, amangowonjezera ku chakudya, asanalowe mu selo, kudalira selo kinetics ndi impellers. kusakaniza.

Mwala umayenera kudulidwa moyenerera mpaka kukula kwake kuti amasule mcherewo, nthawi zambiri ma mesh 100 kapena kupitilira apo (150 microns).Kenako imasakanizidwa ndi madzi kuti ikhale yolimba kwambiri (nthawi zambiri kuyambira 5% mpaka 20%), zomwe zimabweretsa kuchira bwino kwa mchere.Izi zimatsimikiziridwa mu labotale gulu flotation maselo, kuthamanga angapo mayesero kudziwa aliyense determinant ndondomeko.

Mitundu yamakina oyandama imasiyananso mosiyanasiyana, koma onse ndi ofanana kwambiri, chifukwa amalowetsa mpweya pansi pamadzi, ndikuumwaza muselo.Ena amagwiritsa ntchito zowulutsira, makina opondereza mpweya, kapena chowongolera choyandama chomwe chimapanga malo pansi pake ndikukokera mpweya mumakina, kudzera papaipi yoyimilira yomwe imakhalanso ndi shaft.Zili mwatsatanetsatane wa njira yobweretsera mankhwala, mpweya ndi mchere m'madzi zomwe zimapangitsa kuti zikhale zosiyana.

Ndipo monga ndemanga, ndawonapo zambiri za voodoo ndi zabodza zaukadaulo wamakina akuyandama kuposa chilichonse kuyambira masiku amafuta a njoka ku Old West.Ndikwanzeru kumamatira ndi mtundu wabwino womwe umagwiritsidwa ntchito kwambiri pakuyandama kwa mchere womwe ukufunidwa.

Kupititsa patsogolo kumodzi kwakukulu kwakhala kugwiritsa ntchito Column Flotation ngati selo yoyandama yoyeretsa mumakampani amkuwa (ndi mafakitale ena ochepa).Imapanga chinthu choyeretsa, ndipo imakhala yogwira mtima kwambiri ngati selo yoyeretsa, nthawi zambiri, kusiyana ndi maselo oyandama.Ma cell a flotation cell anayamba kuonekera m’zomera chakumapeto kwa zaka za m’ma 1970 mpaka m’ma 1980 ndipo anavomerezedwa kwambiri m’ma 1990.Njira yayikulu yokhala ndi ma cell oyandama wamba yakhala Yaikulu ndi Yabwinoko, yokhala ndi mayunitsi akuluakulu akubwera pamsika zaka makumi angapo zapitazi.
