3.Introduction i ka Sodium Metabisulfite i ka hoʻohana ʻana i ka hoʻoili ʻana i ka mineral metala
Hoʻohana nui ʻia ka Sodium Metabisulfite no ka ʻoihana mining.ʻO nā ʻano o ka hoʻoili ʻana i ka mineral penei:
Kaumaha |Mākēneki hoʻokaʻawale |Koho uila |Lanakila |koho kemika |Koho koho kii |Koho koho |ʻOhi lima
Flotation: ʻO Flotation ke ʻano o ka hoʻokaʻawale ʻana i nā minelala pono mai ka ʻaila, ma muli o nā waiwai kino a me nā kemika o nā ʻāpana mineral.Aneane hiki ke hoʻohana ʻia ka ʻai a pau i ka hoʻokaʻawale ʻana i ka flotation.
Hoʻohana mau ʻia nā mea hoʻoheheʻe hoʻoheheʻe i ka flotation: ʻohi, mea hoʻohua, mea hoʻololi.I waena o lākou, ua komo pū ka mea hoʻololi i ka inhibitor, activator, pH adjusting agent, dispersing agent, flocculant, etc.
Mea ho'opa'a: 'O ka mea ho'opa'a he mea ho'ohuehue e ho'ololi i ka hydrophobicity o ka ili kolakela, e ho'opili ai i ka pōpō mineral planktonic.ʻO Xanthate, ka pauka ʻeleʻele ka mea hōʻiliʻili anionic.
Ka lana o ke kēpau a me ka zinc ores
ʻO Galena (ʻo ia hoʻi ka PBS) he mineral maʻamau, he ʻano sulfide.Hoʻohana mau ʻia ka Xanthate a me ka pauka ʻeleʻele ma ke ʻano he mea hopu hopu (ʻo ka potassium dichromate kahi mea hoʻopaneʻe maikaʻi).
ʻO ka Sphalerite (ZnS) ka hui kemika he mau minela sulfide e like me ZnS, Crystals.
He nāwaliwali a ʻaʻole i loaʻa ka mana hopu o ka alkyl xanthate kaulahao pōkole ma ka sphalerite.Hiki ke koho ʻia ʻo ZnS a i ʻole Marmatite me ka hoʻāla ʻole ʻia e ke ʻano kaulahao lōʻihi xanthate.
I ka wā e hiki mai ana, e hoʻomau nā noi o nā mea hopu xanthate i ke kūlana mana.I mea e hoʻololi ai i ka koi o ka Sphalerite flotation paʻakikī, pono ka hui ʻana o ka lāʻau lapaʻau, he ala maikaʻi nō hoʻi ia e paʻi piha i ka hiki o ka lāʻau lapaʻau.
ʻO ka mea hoʻopiʻi flotation nui penei:
1. He ikaika ko ka Lime (CaO) i ka wai, hana ʻia me ka wai e hana i ka lime Ca(OH)2.Hoʻohana ʻia ka lime no ka hoʻomaikaʻi ʻana i ka pH o ka pulp, kaohi i nā mineral sulfide hao.I ka sulfide copper, ke kēpau, zinc ore, pili pinepine me ka sulfided iron ore.
2. ʻO ka Cyanide (KCN, NaCN) he mea hoʻomalu maikaʻi no ka hoʻokaʻawaleʻana i ke kēpau a me ka zinc.I loko o ka pulp alkaline, piʻi ka manaʻo o CN, kahi i makemake i ka pale.
3. ʻO ka sterling o Zinc Sulfate he keʻokeʻo keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai, ʻo ia ka mea paʻa o ka sphalerite, maʻamau i ka pulp alkaline he hopena o ka inhibition.
4. ʻO ke kī e pāʻani ana i nā hana inhibition i ka sulfite, sulfite, SO2 ka nui HSO3－.Hoʻohana nui ʻia ka sulfur dioxide a me ka sub sulfuric acid (paʻakai) i ka pale ʻana i ka Pyrite a me ka sphalerite.ʻO ka pulp mine acid nāwaliwali i hana ʻia me ka lime mai Sulfur dioxide (pH=5～7), a i ʻole e hoʻohana pū i ka Sulfur dioxide, zinc sulfate, ferrous sulfate a me ka ferric sulfate ma ke ʻano he inhibitor.No laila ua kāohi ʻia ka galena, pyrite, sphalerite.Hiki ke ho'āla ʻia ka sphalerite i hoʻopaʻa ʻia e ka liʻiliʻi o ke keleawe sulfate.Hiki nō hoʻi ke hoʻohana i ka Sodium thiosulfate, sodium metabisulfite e pani ai i ka sulfite, e kāohi i ka sphalerite a me nā pyrite hao (ʻike mau ʻia ʻo FeS2).
