Inzira yo guhinduranya ifu isanzwe isobanurwa nkigikorwa cyumubiri-cyimiti, aho imyunyu ngugu ikururwa, kandi ikiyegeranya hejuru yigituba, ikajyanwa hejuru yakagari, aho ikuzura ikajya kumesa. . kumashini isanzwe ya flotation, iri kumpera zinyuranye zakagari kuva kugaburo, kwemeza ko urugendo rwihuta rwuburebure bwakagari kanyuze muri banki nyinshi zirimo impeller-diffusers, mbere yo gusezererwa nkumurizo.

Ubwoko butandukanye bwimiti igira uruhare muguhindagurika, nibindi byinshi birashobora kubigiramo uruhare.Icyambere nuwamamaza cyangwa umuvandimwe.Iyi miti ikora gusa imbaraga nyinshi zihagije kugirango igere hejuru itavunitse.Ingano yigituba ni ngombwa, nayo, kandi icyerekezo ni gitoya, kubera ko gitanga ubuso bunini (guhuza amabuye y'agaciro byihuse), kandi bifite ituze ryinshi.Ibikurikira byegeranya reagent nubushakashatsi bwibanze buzakora isano hagati yubutare bwihariye hejuru yububiko.Abakusanyirizaga adsorb hejuru yubutaka cyangwa bakabyara imiti hamwe nubutare, bikemerera kuguma bifatanye kugirango bijye kumesa.Inzoga na acide nkeya ni ubwoko bubiri bwimiti yabakusanyirizo bakunze gukoreshwa mugutunganya amabuye y'agaciro.

Hariho kandi reagent nkeya zikoreshwa, nka depressors, kugirango ziveho ibice kugirango bitazubahiriza ibibyimba byinshi, pH ihindura imiti, hamwe nubushakashatsi bukora.Ibikoresho bikora bifasha muburyo bwo gukusanya hamwe nubutare bwihariye bugoye kureremba.

Ibigo nka Cytec, Nalco, na Chevron Phillips Company Chemical ni byo bitanga umusaruro wubwoko bwose bwimiti ya flotation.

Byaba byiza, reagent zizongerwaho mukigega gikonjesha, hamwe na agitator, mbere yo kujya muri selire flotation, ariko mubihe byinshi, byongewe gusa kubiryo, mbere yuko byinjira muri selire, bishingiye kumikorere ya selile na moteri. kuvanga.

Ubucukuzi bw'amabuye y'agaciro bugomba kuba hasi kugeza ku bunini kugira ngo babohore imyunyu ngugu, ubusanzwe mesh 100 cyangwa nziza (microni 150).Noneho ivangwa namazi kugeza kubintu byiza byijana (mubisanzwe kuva kuri 5% kugeza kuri 20%), bizatanga umusaruro mwiza wamabuye y'agaciro.Ibi bigenwa muri laboratoire ya flotation selile, ikora ibizamini byinshi kugirango hamenyekane buri kintu kigena inzira.

Ubwoko bwa mashini ya Flotation buratandukanye cyane, ariko byose birasa cyane, kuberako byinjiza umwuka mumazi, bikabikwirakwiza muri selire.Bamwe bakoresha blowers, compressor de air, cyangwa igikorwa cya moteri ya flotation itera icyuho munsi yacyo kandi bagakurura umwuka mumashini, bakoresheje standpipe nayo irimo uruzitiro.Ari muburyo burambuye bwuburyo bwo kumenyekanisha imiti, umwuka namabuye y'agaciro mumazi atandukanya.

Nkigitekerezo, Niboneye voodoo nyinshi kandi zivuga ko zikora neza mugushushanya imashini ya flotation kuruta ikindi kintu cyose kuva iminsi yamavuta yinzoka yo muburengerazuba bwa kera.Mubisanzwe nibyiza kwizirika ku kirango cyiza gikoreshwa cyane muguhindura amabuye y'agaciro yifuzwa.

Iterambere rimwe ryingenzi kwari ugukoresha Inkingi ya Flotation nkisuku ireremba mu nganda zumuringa (nizindi nganda nke).Itanga ibicuruzwa bisukuye, kandi ikora neza nka selile isukuye, muri rusange, kuruta selile zisanzwe.Ingirabuzimafatizo zo mu bwoko bwa flotation zatangiye kugaragara mu bimera mu mpera za za 1970 no mu myaka ya za 1980 kandi byemerwa cyane na za 90.Inzira nyamukuru hamwe na selile isanzwe ya flotation yabaye Bigger nibyiza, hamwe nibice binini biza kumasoko mumyaka mirongo ishize.
