Ntuziaka zuru oke maka ndị na-ese ihe na-ekpo ọkụ na ọla kọpa

Ihe ndị na-emegharị flotation dị mkpa na ikewapụta mineral ọla kọpa bara uru na nkume mkpofu n'oge usoro ịkwọ ụgbọ mmiri. Ebumnuche bụ isi nke ịkwọ ụgbọ mmiri ọla kọpa bụ imepụta mkpokọta ọla kọpa nwere ike ịre ahịa. Iji mezuo nke a, a na-eji reagents dị iche iche, nke a na-ekewa n'ime ụzọ anọ: ndị nchịkọta, frothers, pH modifiers, na ndị na-ekesa.

1. Ọla kọpa Flotation Collectors

Ndị na-anakọta ihe na-arụ ọrụ dị oke mkpa n'ọkpụkpụ ọla kọpa site n'itinye n'elu mineral ọla kọpa, na-eme ka ha bụrụ hydrophobic. Nke a na-enye ohere ịnweta ọla kọpa na-arapara n'ahụ ikuku ikuku wee bilie n'elu cell flotation. Ndị na-anakọtakarị maka flotation ọla kọpa gụnyere xanthates na dithiophosphates (reagents ojii).

• Xanthates
  Xanthates dị ka ethyl xanthate na pentyl xanthate na-ejikarị eme ihe ndị na-anakọta flotation ọla kọpa. Ha na-agbakọta nke ọma n'elu mineral ọla kọpa, na-eme ka ha dị hydrophobic ma si otú a dị mfe itinye aka na afụ ikuku na cell flotation.

• Dithiophosphates (Black Reagents)
  Dithiophosphate reagents dị ka sodium diisobutyl dithiophosphate (black sodium reagent) na ammonium diisobutyl dithiophosphate (black ammonium reagent) na-ejikarị. Ha na-arụ ọrụ n'otu aka ahụ site n'ịkwalite hydrophobicity nke mineral ọla kọpa, na-eme ka ịkwọ ụgbọ mmiri dị mma.

2. Ụmụnna maka Ọla kọpa Flotation

A na-agbakwunye ndị nne n'ime mkpụrụ ndụ nke na-ese n'elu mmiri iji mepụta afụ kwụsiri ike nke na-ebuga mineral ọla kọpa hydrophobic gaa n'elu cell, ebe enwere ike ịpụpụ ha.

• Mmanụ pine
  Mmanụ pine bụ otu n'ime friji a na-ejikarị eme ihe. Ọ na-etolite oyi akwa froth kwụsiri ike nke na-ebute mineral ọla kọpa n'elu maka nchịkọta.

• Methyl Isobutyl Carbinol (MIBC)
  MIBC bụ frother ọzọ na-ewu ewu, mara maka ọmarịcha frothing na nkwụsi ike ya, nke na-eme ka arụmọrụ flotation dịkwuo mma.

• Polyether Frothers
  A na-ejikwa ogige polyether dị ka polyethylene glycol na polypropylene glycol na mmiri na-ese n'elu ọla kọpa. Ndị a frothers na-enye afụ kwụsiri ike ma na-akwado arụmọrụ flotation ka mma.

3. pH Modifiers maka Ọla kọpa Flotation

Ndị na-eme mgbanwe pH na-ahazi ọnọdụ kemịkalụ nke slurry flotation iji bulie elu mgbake ọla kọpa. Ndị na-eme mgbanwe pH na-agụnye lime, sodium hydroxide, na sulfuric acid.

• Lime na sodium hydroxide
  A na-eji lime na sodium hydroxide na-edozi pH nke slurry, na-eme ka arụ ọrụ flotation ọla kọpa dị. Njikwa pH kwesịrị ekwesị dị mkpa maka ịhọrọ flotation nke ọla kọpa sitere na mineral ndị ọzọ.

• Ndị na-egbochi ihe na ndị na-eme ihe
  Ihe mgbochi dị ka sodium cyanide na ferrous sulfate na-eji iji gbochie mineral ndị na-achọghị ka ị na-ese n'elu mmiri, na-eme ka nhọrọ nke flotation ọla kọpa dịkwuo mma. A na-eji ihe ndị na-eme ihe, dị ka sulfate ọla kọpa, na-eme ka mmiri na-ekpu mmiri nke ọla kọpa sulfide mineral.

4. Dispersants maka ọla kọpa Flotation

Ndị na-ekesa na-eme ka nkesa nke reagents na ihe siri ike dị na flotation slurry, na-eme ka kọntaktị dị mma n'etiti mineral ọla kọpa na reagents flotation.

• polyacrylamides
  Polyacrylamide bụ ihe a na-ejikarị eme ihe nke na-enyere aka igbochi nchịkọta urughuru, na-eme ka mmekọrịta reagent na-arụ ọrụ nke ọma na flotation ọla kọpa.

• Epoxy resins
  A na-etinyekwa resins Epoxy n'ihi na ha na-agbasasị na nrapado nke ọma, na-eme ka usoro flotation n'ozuzu ya dịkwuo elu.
