Ke alakai piha i na mea hoohuoi i ka lele ana o ka aila keleawe

He mea nui nā mea hoʻoheheʻe flotation i ka hoʻokaʻawale ʻana i nā minelala keleawe waiwai nui mai ka pōhaku ʻōpala i ka wā o ke kaʻina hana flotation. ʻO ka pahuhopu nui o ka flotation keleawe ka hana ʻana i kahi concentrate keleawe kūʻai aku. No ka hoʻokō ʻana i kēia, hoʻohana ʻia nā ʻano mea hoʻoheheʻe like ʻole, i hoʻokaʻawale pinepine ʻia i ʻehā mau ʻano nui: nā mea hōʻiliʻili, nā mea frothers , nā mea hoʻololi pH, a me nā mea hoʻolaha.

1. Mea Ohi Copper Flotation

He kuleana koʻikoʻi ka poʻe ʻohi i ka lele keleawe ma ka hoʻopili ʻana i ka ʻili o nā mineral keleawe, e hoʻolilo iā lākou i hydrophobic. ʻO kēia ka mea e hiki ai i nā minela keleawe ke hoʻopili i nā ʻōpū o ka ea a piʻi i luna o ka ʻili o ka flotation cell. ʻO nā mea hōʻiliʻili maʻamau no ka lele keleawe me nā xanthates a me nā dithiophosphates (nā mea ʻeleʻele ʻeleʻele).

• Xanthates
  Hoʻohana nui ʻia nā Xanthates e like me ethyl xanthate a me pentyl xanthate nā mea hoʻoheheʻe keleawe. Hoʻopili maikaʻi lākou ma luna o ka ʻili o nā mineral keleawe, e hoʻolilo iā lākou i hydrophobic a pēlā e maʻalahi ai ke hoʻopili ʻana i nā ʻōhū ea i loko o ke keena flotation.

• Nā Dithiophosphates
  Hoʻohana pinepine ʻia nā mea hoʻopaʻa dithiophosphate e like me ka sodium diisobutyl dithiophosphate (ʻeleʻele sodium reagent) a me ka ammonium diisobutyl dithiophosphate (ʻeleʻele ammonium reagent). Hana like lākou me ka hoʻonui ʻana i ka hydrophobicity o nā minela keleawe, e hoʻomaʻamaʻa i ka flotation pono.

2. Na Frothers no ka Lana keleawe

Hoʻohui ʻia nā frothers i nā cell flotation e hoʻohua i nā ʻōpū paʻa e lawe ana i nā mineral keleawe hydrophobic i ka ʻili o ke kelepona, kahi e hiki ai ke hoʻokuʻu ʻia.

• ʻAilā Pine
  ʻO ka ʻaila pine kekahi o nā frothers maʻamau i hoʻohana ʻia. Hoʻokumu ʻia ia i kahi papa puaʻa paʻa e lawe mai i nā mineral keleawe i ka ʻili no ka hōʻiliʻili ʻana.

• Methyl Isobutyl Carbinol (MIBC)
  ʻO MIBC kekahi frother kaulana, i ʻike ʻia no kāna mau waiwai frothing maikaʻi a paʻa, e hoʻomaikaʻi ai i ka pono o ka flotation.

• Nā Puʻupuʻu Polyether
  Hoʻohana pū ʻia nā pūhui polyether e like me polyethylene glycol a me polypropylene glycol i ka lele keleawe. Hāʻawi kēia mau frother i nā ʻōhū paʻa a kākoʻo i ka hana flotation ʻoi aku ka maikaʻi.

3. Nā mea hoʻololi pH no ka lele keleawe

Hoʻoponopono nā mea hoʻololi pH i nā kūlana kemika o ka slurry flotation e hoʻonui i ka hoʻōla keleawe . ʻO nā mea hoʻololi pH maʻamau e komo pū me ka lime, sodium hydroxide, a me ka sulfuric acid.

• Lime a me ka Sodium Hydroxide
  Hoʻohana ʻia ka Lime a me ka sodium hydroxide e hoʻoponopono i ka pH slurry, e hoʻonui ana i ka hana keleawe keleawe. Pono ka mana pH kūpono no ka lele ʻana o ke keleawe mai nā minerala ʻē aʻe.

• Nā mea pale a me nā mea hana
  ʻO nā mea pale like ʻO ka sodium Cyanide a hoʻohana ʻia ka ferrous sulfate e pale aku i nā minela i makemake ʻole ʻia mai ka lana ʻana, e hoʻomaikaʻi ana i ka koho o ka lele keleawe. Hoʻohana ʻia nā mea hana, e like me ke keleawe sulfate, e hoʻomaikaʻi i ka lele ʻana o nā minerala keleawe sulfide.

4. Nā Dispersants no ka lele keleawe

Hoʻomaikaʻi nā Dispersants i ka hāʻawi ʻana i nā reagents a me nā ʻāpana paʻa i loko o ka slurry flotation, e hōʻoiaʻiʻo ana i ka pilina maikaʻi ma waena o nā mineral keleawe a me nā reagents flotation.

• ʻO Polyacrylamide
  ʻO ka polyacrylamide kahi dispersant i hoʻohana nui ʻia e kōkua i ka pale ʻana i ka hoʻohui ʻana o nā ʻāpana, e hōʻoiaʻiʻo ana i ka pilina reagent kūpono a me ka lele keleawe.

• Epoxy resins
  Hoʻopili ʻia nā resins epoxy ma muli o kā lākou hoʻopuehu maikaʻi a me nā waiwai adhesive, e hoʻonui ai i ke kaʻina holo holo holoʻokoʻa.
