I-ore dressing ngumsebenzi wemveliso olungiselela izinto eziluhlaza zokunyibilikisa isinyithi kunye noshishino lweekhemikhali. Ukuqunjelwa kwefroth kuye kwaba yenye yezona ndlela zibalulekileyo zokucubungula izimbiwa. Phantse zonke izibonelelo zezimbiwa zinokwahlulwa ngokusebenzisa ukuqunjelwa.
I-Flotation okwangoku isetyenziswa kakhulu ekucutshungulweni kwee-ore zesinyithi ezine-ferrous ezilawulwa yi-iron kunye ne-manganese, ezifana ne-hematite, i-smithsonite, kunye ne-ilmenite; ii-ore zesinyithi ezixabisekileyo ezifana negolide nesilivere; ii-ore zesinyithi ezingezizo ze-ferrous eziquka i-copper, i-lead, i-zinc, i-cobalt, i-nickel, i-molybdenum, kunye ne-antimony, ezifana nee-sulfide minerals ezifana ne-galena, i-sphalerite, i-chalcopyrite, i-chalcocite, i-molybdenite, kunye ne-pentlandite, kunye nee-oxide minerals ezifana ne-malachite, i-cerussite, i-hemimorphite, i-cassiterite, kunye ne-wolframite; ii-non-metallic salt minerals ezifana ne-fluorite, i-apatite, kunye ne-barite; kunye nee-soluble salt minerals ezifana ne-sylvite kunye ne-rock salt. Ikwasetyenziselwa ukwahlula ii-non-metallic minerals kunye ne-silicates, kubandakanya amalahle, i-graphite, i-sulfur, i-diamond, i-quartz, i-mica, i-feldspar, i-beryl, kunye ne-spodumene.
I-Flotation iqokelele amava amaninzi kwicandelo lokucubungula izimbiwa, kunye nophuhliso oluqhubekayo lwetekhnoloji. Nezimbiwa ezikumgangatho ophantsi nezintsonkothileyo ezazikade zithathwa njengezingasetyenziswa kwimizi-mveliso ngoku zinokufunyanwa kwaye zisetyenziswe (njengezixhobo zesibini) ngokuqubha.
Njengoko izixhobo zezimbiwa ziya zisiba mbi ngakumbi, kunye neeminerali eziluncedo ezisasazwa kakuhle kwaye zahlukile kwiintsimbi, ubunzima bokuhlukana buyanda. Ukunciphisa iindleko zemveliso, amashishini afana ne-metallurgy kunye neekhemikhali afuna imigangatho ephezulu yomgangatho kunye nokuchaneka kwezinto ezisetyenzisiweyo, oko kukuthi, iimveliso ezahlulweyo.
Kwelinye icala, kukho imfuneko yokuphucula umgangatho; kwelinye icala, ukutyibilika kwe-flotation kubonisa ngakumbi iingenelo kunezinye iindlela zokujongana nomceli mngeni weeminerali ezicolekileyo ezinzima ukuzahlula. Iye yaba yindlela yokucubungula izimbiwa esetyenziswa kakhulu nethembisayo namhlanje. Ekuqaleni isetyenziswa kwiiminerali ze-sulfide, ukutyibilika kwe-flotation kuye kwanda kancinci kancinci kwaba ziiminerali ze-oxide, iiminerali ezingezizo zesinyithi, nezinye. Okwangoku, iibhiliyoni zeetoni zeeminerali zicutshungulwa ngokutyibilika kwe-flotation kwihlabathi liphela minyaka le.
Kwiminyaka yakutshanje, ukusetyenziswa kwetekhnoloji yokudada akusapheleli nje kubunjineli bokucubungula izimbiwa kodwa kuye kwanda kwaya kukhuseleko lokusingqongileyo, i-metallurgy, iphepha, ezolimo, iikhemikhali, ukutya, izixhobo, amayeza, kunye nebhayoloji.
Umzekelo, i-flotation isetyenziselwa ukubuyisa izinto eziluncedo kwiimveliso eziphakathi ze-pyrometallurgy, i-volatiles, kunye ne-slags; ukubuyisa iintsalela ze-leach kunye neemveliso ezitshileyo kwi-hydrometallurgy; ukususa iphepha elisetyenzisiweyo kunye ne-fiber recovery kwi-pulp waste liquid kwishishini leekhemikhali; kunye nokukhupha i-oyile enzima ekrwada kwisanti esecaleni komlambo, ukwahlula ungcoliseko oluncinci oluqinileyo, ii-colloids, iibhaktheriya, kunye nokulandelela ukungcola kwesinyithi kwi-lindle, ezisetyenziswa kakhulu kubunjineli bendalo.
Ngokuphuculwa kweenkqubo kunye neendlela zokudada, kunye nokuvela kwee-reagents kunye nezixhobo ezintsha nezisebenzayo zokudada, ukuhambahamba kuya kufumana ukusetyenziswa okubanzi kumashishini nakwiindawo ezininzi. Kubalulekile ukuqaphela ukuba ukusetyenziswa kweenkqubo zokudada kubandakanya iindleko eziphezulu zokucubungula ngenxa yee-reagents (xa kuthelekiswa nokwahlulwa kwemagnethi kunye nomxhuzulane); iimfuno ezingqongqo zobungakanani bezinto zokutya; izinto ezininzi ezinefuthe kwinkqubo yokudada, ezifuna ukuchaneka kobuchwepheshe obuphezulu; kunye namanzi amdaka aqulethe ii-reagents ezisele ezinokonakalisa okusingqongileyo.
