Ta'iala A'oa'o ile Fa'a'au'au Fa'a'au'au ile Fa'a'au'a Kopa

O mea fa'afefete e taua tele i le tu'ueseeseina o minerale 'apamemea taua mai ma'a otaota i le taimi o le fa'afefeteina. O le sini autu o le fa'afefeteina apamemea o le fa'atupuina lea o se 'apamemea fa'atau. Ina ia ausia lenei mea, e faʻaaogaina reagents eseese, e masani ona faʻavasegaina i ni vaega autu se fa: aoina, fuifui, suiga pH, ma dispersants.

1. Fa'aputu'e Kopa Fa'aputu

E taua tele le sao a le au aoina i le fa'afefeteina o kopa e ala i le fa'apipi'i atu i luga o minerale apamemea, ma avea ai i latou o le hydrophobic. O lenei mea e mafai ai e minerale kopa ona pipii i le ea ma oso aʻe i luga o le sela faʻafefe. O tagata aoina masani mo le fa'afefe kopa e aofia ai xanthates ma dithiophosphates (reagents uliuli).

• Xanthates
  Xanthates e pei ole ethyl xanthate ma le pentyl xanthate e fa'aaogaina lautele fa'aputu apamemea. E fa'afefeteina lelei i luga o minerale apamemea, e fa'afefeteina ai ma fa'afaigofie ai ona fa'apipi'i i pulu ea i totonu o le potu fe'avea'i.

• Dithiophosphates (Su'i Uliuli)
  Dithiophosphate reagents e pei ole sodium diisobutyl dithiophosphate (black sodium reagent) ma ammonium diisobutyl dithiophosphate (black ammonium reagent) e masani ona faʻaaogaina. Latou te galulue faʻapena e ala i le faʻaleleia o le hydrophobicity o minerale kopa, faʻafaigofie le faʻafefeteina lelei.

2. Frothers mo Flotation Copper

E fa'aopoopo fo'i frothers i sela fa'afefete e fa'atupu mai ai pupuni mautu e feavea'i minerale apamemea hydrophobic i luga ole sela, lea e mafai ai ona fa'amama ese.

• Suauu Pine
  O le suau'u paina o se tasi lea o fuifu e masani ona fa'aaogaina. E fai ai se fa'afu'e mautu e aumai ai minerale apamemea i luga mo le aoina.

• Methyl Isobutyl Carbinol (MIBC)
  O le MIBC o se isi frother lauiloa, ua lauiloa ona o mea lelei faʻafefeteina ma mautu, lea e faʻaleleia ai le faʻaogaina lelei.

• Polyether Frothers
  Polyether compounds e pei o le polyethylene glycol ma le polypropylene glycol o loʻo faʻaaogaina foi i le faʻafefe apamemea. O nei frothers e maua ai ni pulu mautu ma lagolagoina lelei le fa'atinoina o le fa'afefeteina.

3. pH Suiga mo le Fa'a'ofuofu Kopa

O suiga o le pH e fa'atulafonoina tulaga fa'a-kemikolo o le slurry fa'afefete ina ia fa'ateleina toe fa'aleleia apamemea. O suiga masani o le pH e aofia ai le lime, sodium hydroxide, ma le sulfuric acid.

• Lime ma le Sodium Hydroxide
  Lime ma le sodium hydroxide e faʻaaogaina e fetuutuunai ai le pH slurry, faʻamalieina le faʻaogaina o le kopa. O le pulea lelei o le pH e taua tele mo le filifilia o le kopa mai isi minerale.

• Inhibitors ma Activators
  Inhibitors pei Sodium Cyanide ma ferrous sulfate o loʻo faʻaaogaina e puipuia ai minerale e le manaʻomia mai le faʻafefe, faʻaleleia atili le filifilia o le faʻafefe apamemea. Activators, e pei o le kopa sulfate, e faʻaaogaina e faʻaleleia ai le faʻafefe o minerale sulfide kopa.

4. Fa'asalalauina mo le Fa'a'ofuofu Kopa

O lo'o fa'aleleia e tagata fa'asalalauina le tufatufaina atu o mea fa'afoliga ma mea fa'amalo i totonu o le slurry fa'afefe, fa'amautinoaina le feso'ota'i lelei atu i le va o minerale 'apamemea ma mea fa'afefe.

• polyacrylamides
  O le Polyacrylamide o se faʻasalalauga lautele faʻaaogaina e fesoasoani e puipuia ai le faʻapipiʻiina o vaega, faʻamautinoaina le lelei o fegalegaleaiga faʻafefe ma faʻafefe apamemea.

• Epoxy Resins
  Epoxy resins e faʻaaogaina foʻi ona o lo latou faʻasalalau lelei ma mea faʻapipiʻi, faʻaleleia le faʻagasologa o le faʻafefe.
