Nthawi zambiri othandizira amagwiritsidwa ntchito amatenga gawo lofunikira m'madzi opangira mchere ndipo amagwiritsidwa ntchito kuwongolera ndikuwongolera machitidwe a mchere. Zowonjezera zopangira mineral zogwiritsidwa ntchito zimaphatikizapo osonkhanitsa, othandizira, oyang'anira ndi zoletsa.
imodzi. Oso
Wokhometsayo amasintha motsatira pakati pa tinthu ta michere ndi thovu posintha ma hydrophobicity wa mchere wamchere, potero kukwaniritsa maluwa amchere.
1. Mankhwala a mankhwala a xanthates: xanthate ndi mchere wa dithiocarbonates. Zofala zimaphatikizapo ethyl xanthate (C2HocsShS2na) ndi isopropyl xanthate (C3hniocSS2na). Magawo: kuthekera kwamphamvu, koma kusadetsa bwino, koyenera kubwereketsa mchere wa sulfiside. Kugwiritsa: Ntchito zogwiritsidwa ntchito potulutsa kwa mkuwa kwa ore, kutsogolera Ore ndi zinzi. Zambiri: Mumkuwa kwa orepper, kupsinjika kwa ethyl xanthate yogwiritsidwa ntchito ndi 30-100 g / t, ndipo chiwombacho chimatha kupitilira 90%.
2.dithiosphate
Mankhwala: Mankhwala akuda ndi mchere wa dithiofosphate, wamba ndi sodium diitiophosphate (Nao2s2 (C2h5) 2) 2). Magawo: Kuwongolera bwino komanso kusankhidwa bwino, koyenera kulongosola mchere wa sulfide monga mkuwa, kutsogolera, ndi zinc. Kugwiritsa: Ntchito zogwiritsidwa ntchito potulutsa golide, siliva ndi zamkuwa. Data: Kutulutsa kwa golide
3.carkylates
Mankhwala: Carboxylates ndi mankhwala okhala ndi magulu a carboxylic acid, monga sodium oleate (C18h34na2). Zoyenera: zoyenera kubwereketsa kwa mchere wa mchere komanso michere yopanda zitsulo. Kugwiritsa: Ntchito zogwiritsidwa ntchito pakugwedeza mchere monga hematite ndi petite. Zambiri: Kutulutsa kwa Aputa, kuchuluka kwa sodium oleate ndi 50-150 g / t, ndipo chiwombacho chimatha kupitilira 75%.
awiri. Ukoma
Chingwecho chimagwiritsidwa ntchito kupanga chithovu chokhazikika komanso chofanizira pa njira yolowerera kuti athandizire kulumikizana ndi kupatukana kwa michere.
1. Mankhwala opangira mafuta a paini: gawo lalikulu ndi ma terpene mankhwala, omwe ali ndi matupi abwino. Magawo: kuthekera kwamphamvu kwamphamvu komanso kukhazikika kwa thovu. Ntchito: Kugwiritsidwa ntchito kwambiri pakukongoletsa kwa sulfide ma sulfide ndi michere yopanda zitsulo. Zambiri: Pakutha kwapafupiku kwa mkuwa, kuchuluka kwa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa pa paini ndi 10-50 g / t. 2. Mankhwala a mankhwala a butanol: mattanol ndi mowa woledzera ndi utomoni wovuta. Magawo: kuthekera kokwanira komanso kukhazikika kwa chiphona. Kugwiritsa: Kuyenera kubwereka mkuwa, kutsogolera, zinki ndi michere ina. Data: Pakutsogolera ore scottition, butanol imagwiritsidwa ntchito pozungulira 5-20 g / t.
zitatu. Okonzanso amagwiritsidwa ntchito kusintha mtengo wa slurry, choletsa kapena kuyambitsa mawonekedwe a mchere, potero kukonza njira zowonekera.
1. Mankhwala a mankhwala: Gawo lalikulu ndi calcium hydroxide (ca (o) 2), omwe amagwiritsidwa ntchito kusintha mtengo wa st. Magawo: mtengo wa pH umatha kusintha pakati pa 10-12. Kugwiritsa: Kugwiritsidwa ntchito kwambiri pakukongoletsa kwa mkuwa, kutsogolera ndi zinc ores. Data: Pakuwoneka kwapafupipafupi kwa mandimu, kuchuluka kwa laimu komwe kumagwiritsidwa ntchito ndi 500-2000 g / t.
2. Mankhwala a mankhwala amtundu wa mkuwa: Copper Sulfate (CUSO4) ndi oxidant yamphamvu ndipo nthawi zambiri imagwiritsidwa ntchito kuyambitsa mchere wa sulfide. Magawo: Zochita zoyambitsa ndizodabwitsa ndipo ndizoyenera kugwedezeka kwa michere monga pyrite. Ntchito: pakuyambitsa mkuwa, kutsogolera, ndi michere ya zinzi. Data: Pakuwongolera kuloza, kupsinjika kwa sulfate yogwiritsidwa ntchito ndi 50-200 g / t.
