Uhlelo lwamakhemikhali lwesitshalo se-flotation luhlobene nezici ezifana nohlobo lwe-ore, ukugeleza kwenqubo, kanye nezinhlobo zemikhiqizo yokucubungula amaminerali edinga ukutholakala. Imvamisa kunqunywa ngokuhlolwa kokuzikhethela kwama-ores noma ukuhlolwa kwezimboni. Uhlelo lwezemithi luyinto ebalulekile ethinta izinkomba zobuchwepheshe nezomnotho zokucubungula amaminerali. Ungangeza kanjani umthamo ofanele wama-Pharmaceuticals ubalulekile.
1. Izinhlobo zama-ejensi amakhamikhali zingahlukaniswa izigaba ezintathu ngokuya ngemisebenzi yazo (1) ama-ejenti ama-foaming: izinto ezisebenza nge-organic zisatshalaliswa esibonakalayo se-water-vapor interface. Kusetshenziselwa ukukhiqiza ungqimba lwegwebu olungakwazi ukuntanta amaminerali. Ama-Foaming Agents afaka u-perine oyela, uwoyela we-cresol, ama-alcohols, njll. (2) Ukuqoqa i-ejenti: Ukuqoqa i-ejenti kungashintsha ama-hydrophobicity we-bubble yamaminerali futhi wenze izinhlayiya zamaminerali ezintantayo zinamathela ku-bubble. Abaqoqi abavame ukusetshenziswa bafaka umuthi omnyama, i-xanthate, umuthi omhlophe, ama-fatty acid, amafutha, uwoyela, njll. (3) I-adtiaster kanye ne-inhibitor, okuguqula indawo yezinhlayiya zamaminerali futhi ithinta umsebenzi wamaminerali kanye nabaqoqi ② activator: sulfate yethusi, i-sodium sulfide; ③ Inhibitors: I-Lime, usawoti wegazi ophuzi, i-sodium sulfide, i-sulfur dioxide, i-sodium cyanide, i-zinc sulfate, i-collouble ye-collouble, isitashi, i-soluble colmoid, isitashi, i-software ye-polymer ephezulu ye-moleculate, njll; Abanye: Ama-ejenti wezamanzi, ama-ejenti antantayo, ama-solubililizer, njll.
2. Imithamo yama-reagents: umthamo wama-reagents kufanele ube nje ngesikhathi sokufakelwa. Umthamo onganele noma owengeziwe uzothinta inkomba yokucubungula amaminerali, futhi umthamo owedlulele uzokwandisa izindleko zokucubungula amaminerali. Umthelela wemithamo ehlukene yama-reagents kwizinkomba ze-flotation: ① umthamo onganele umqoqi uzoholela ekutheni ama-hydrophobicicity anganele amaminerali, lapho kunciphisa isilinganiso sokuthola amaminerali, ngenkathi umthamo ngokweqile uzonciphisa ikhwalithi yokugxila futhi ulethe ubunzima bokudonsa kanzima; Umthamo onganele we-ejenti we-foaming uzoholela ekuqineni okubi kwamagwebu, futhi umthamo owedlulele uzodala into ethi "groove egijima"; Uma umthamo we-activator umncane kakhulu, umphumela wokuqalisa uzoba mpofu, futhi umthamo owedlulele uzobhubhisa inqubo ye-flotation. Ukukhetha; ④ Imithamo enganele ye-inhibitors izoholela ekuhlolweni okuphansi kwebanga, futhi amanani amaningi ezinhlanga azovimbela amaminerali okufanele aphume futhi anciphise izinga lokutakula. 3 Ama-ejenti ane-solubility amanzi ampofu, njenge-Xanthate, i-amylanine, i-sodium silicate, i-sodium carbonate, i-sulfate yethusi, i-sulfide, njll. " Ama-ejenti angenakufakwa emanzini kufanele achithwe ku-solvent kuqala, bese engezwa esikhaleni esinamanzi, njengabaqoqi be-anine. Ezinye zingezwa ngqo, njenge # 2 kawoyela, # 31 I-Black Powder, i-Oleic acid, njll. Okwenziwa ngemithi ancibilika kalula emanzini futhi inomthamo omkhulu, ukugxilwa kokulungiswa ngokuvamile kuya ku-20%. Isibonelo, i-sodium sulfide ilungiselelwe ngo-15% lapho isetshenziswa. Okwenziwa ngemithi ancibilike kabi emanzini, izixazululo ze-organic zingasetshenziswa ukuzichitha bese zilungele izixazululo zokuhlushwa okuphansi. Ukukhetha kwendlela yokulungiselela amakhemiye kususelwa ikakhulu kwizakhiwo, izindlela zokungeza nemisebenzi yezemithi. Izindlela zokulungiselela ezijwayelekile yilezi: ① Lungiselela i-2% kuya ku-10% khambi elinamanzi. Iningi lezemithi lezemithi le-ter-soluble lilungiselelwe ngale ndlela (njenge-xanthate, i-sulfate yethusi, i-sodium silicate, njll. Ngemithi ethile eqinile engancibiliki kalula, ingalungiswa ibe yi-Emulsions. Imvamisa abaqoqi kanye nama-ejenti amagwebu angavuselelwa imizuzu engu-1-2, kepha amanye ama-ejenti adinga ukushukumisa isikhathi eside.
