ʻO ka hoʻohana ʻana i ka Sodium Hexametaphosphate i ka Mineral Flotation

Introduction

ʻO ka mineral flotation kahi ala i hoʻohana nui ʻia i ka ʻoihana mining e hoʻokaʻawale i nā minerala waiwai mai nā mineral gangue. Ke hilinaʻi nei ia i nā ʻokoʻa o nā waiwai kino a me nā waiwai kemika o nā ʻili mineral. ʻO ka sodium hexametaphosphate, me kāna ʻano kemika kū hoʻokahi a me nā waiwai, ua loaʻa i nā noi nui i loko ʻO ka lele ʻana o ka minerala kaʻina hana. Hoʻopili kēia ʻatikala i nā ʻano like ʻole o kona hoʻohana ʻana i ka flotation mineral.

Nā waiwai o ka Sodium Hexametaphosphate

ʻO ka sodium hexametaphosphate he pūhui polymer inorganic. ʻIke ʻia ʻo ia ma ke ʻano he aniani aniani a i ʻole ka pauka keʻokeʻo. Hiki ke hoʻoheheʻe ʻia i loko o ka wai, a he alkaline kona wai. I ka lewa, loaʻa iā ia kekahi degere o ka hygroscopicity. Hoʻokumu kēia mau waiwai kino a me ke kemika i ke kumu no kāna hana i ka flotation mineral.

Nā Hana ma ka Mineral Flotation

Kaumaha

1. Ka hoʻopaʻa ʻana i nā Minerale Silicate a me Carbonate

• He kūpono ka sodium hexametaphosphate i ka pale ʻana i nā minerala quartz a me silicate. I ka lele ʻana o kekahi mau ores, e like me nā mea i loaʻa i ka feldspar a me ka mika, hiki iā ia ke hoʻopili i ka ʻili o kēia mau mineral silicate. No ka laʻana, i ka flotation o zirconium ores, hiki iā ia ke hoʻemi i ka floatability o nā feldspar pili a me nā minerala silicate gangue ʻē aʻe ma o ka adsorbing ʻana ma ko lākou mau ʻili.

• Hōʻike pū ia i nā hopena pale i nā minerala carbonate e like me ka calcite a me ka limestone. I ka holo ana o ka phosphate ores kahi calcite he mineral gangue maʻamau, ʻO ka sodium hexametaphosphate hiki ke hana me nā iona calcium ma ka ʻili calcite. Hoʻokumu ia i nā pūhui paʻa e hoʻonui ai i ka hydrophilicity o ka ʻili calcite, e liʻiliʻi ai ke hoʻopili ʻia e ka ʻohi, no laila e hoʻokō ai i ke kumu o ka inhibition.

2. Mechanism Hoʻopaʻa

• ʻO kekahi o nā hana hoʻopale nui e pili ana i kona hopena me nā ion metala ma ka ʻili mineral. I ka wā e pili ana i nā minelala i loaʻa nā ion metala he nui, hiki i ka sodium hexametaphosphate ke hana i nā pūhui paʻa me kēia mau ion metala. I ka nickel ore flotation, e hana me nā ion kūikawā ma ka ʻili o ka serpentine, ka mea e pale ai i ka flotability o ka serpentine.

• Eia kekahi, i loko o ka wai wai, hiki i ka sodium hexametaphosphate ke ionize. Hiki iā ia ke hana me nā ion calcium ma ka ʻili mineral a me ka pae wai. I ka hoʻokaʻawale ʻana o ka calcite a me ka cassiterite, ʻo ka hui i hana ʻia ma ka ʻili calcite ʻaʻole e pili wale i ka calcite akā hiki ke adsorb ma ka ʻili cassiterite, e hōʻemi ana i ka koho o ka inhibition a me ka hoʻohaʻahaʻa ʻana i ka adsorption o ka ʻohi ma ka ʻili mineral.

Hoʻopuehu

1. Ka hoʻopuehu ʻia o ka Pulp Mineral

• I nā kaʻina hana hoʻoheheʻe, ʻoi aku hoʻi no kekahi mau ores me nā minerala maikaʻi a i ʻole kiʻekiʻe - lepo - ʻano ores, he mea koʻikoʻi ka hoʻopuehu ʻana o ka pulp mineral. Hiki i ka sodium hexametaphosphate ke hana koʻikoʻi ma ke ʻano he dispersant. No ka laʻana, i ka flotation o nickel - pyrite ores e pili ana me ka serpentine, hoʻohui i ka nui kūpono o ka sodium hexametaphosphate hiki ke hoʻopuehu i ka flotation pulp. ʻO kēia no ka mea e hōʻemi ana i ka uhi ʻana o ka serpentine ma luna o ka nickel - pyrite, ka mea e pono ai ka hoʻihoʻi hou ʻana o ka nickel - pyrite.

2. Hoʻopuehu Mechanism

• Hiki i ka sodium hexametaphosphate ke hoʻohaʻahaʻa i ka ʻili o nā minerala. Ma muli o ka hopena, piʻi ka mana hoʻokuʻu electrostatic ma waena o nā ʻāpana mineral. ʻO kona molecular structure, kahi hui polymer linear me ka lōʻihi o ke kaulahao ma kahi o 20 - 100 mau ʻāpana, ke hoʻopili ʻia ma ka ʻili mineral, hiki ke hoʻonui i ka hopena steric hindrance ma waena o nā ʻāpana. I ka lele ʻana o kekahi ores phosphate maikaʻi, hiki i kēia hopena dispersion ke pale i ka hōʻuluʻulu ʻana o nā minerala phosphate a me nā gangue, e hoʻomaikaʻi i ka pono kaʻawale.

Hoʻohana ʻia i loko o nā ʻokoʻa Mineral Flotation

Holoi ʻOka Phosphate

1. Hoʻokaʻawale koho

• I ka phosphate ore flotation, hoʻohana pinepine ʻia ka sodium hexametaphosphate e hoʻokaʻawale i nā mineral phosphate mai nā mineral gangue. Hoʻopili pinepine ʻia ka Phosphate ores me nā mineral gangue like ʻole me ka calcite, dolomite, a me nā mineral silicate. Hiki i ka sodium hexametaphosphate ke kaohi i kēia mau mineral gangue. Ma ke kaʻina hana hoʻohuli hope o kekahi ores phosphate, hiki ke hoʻonui i ka nui o ka sodium hexametaphosphate i ka pae a me ka hoʻihoʻi ʻana o ka phosphate concentrate. Hiki iā ia ke hana me nā minerala non-phosphate me ka ʻole o ka pane ʻana me nā minela phosphate, pēlā e hoʻomaikaʻi ai i ka koho ʻana o ka flotation mineral phosphate.

2.Effect on Foam Stability

• He hopena nō hoʻi ia i ka paʻa o ka foam i ka phosphate ore flotation. ʻO ka ʻōhū i loko o ke kaʻina flotation ke kuleana i ka ʻohi ʻana i nā mineral phosphate. Hiki i ka sodium hexametaphosphate ke hoʻonui i ka paʻa o ka huʻa. Hiki iā ia ke hoʻohua i ka nui o nā ʻōpala paʻa, e kōkua ana i ka hoʻomaikaʻi ʻana i ka hopena hōʻiliʻili o nā mineral phosphate. Hiki ke lawe maikaʻi ʻia nā minela phosphate e ka ʻōpala paʻa i ka ʻili, a laila e hoʻomaikaʻi ai i ka pono o ka flotation a me ka pae.

Holoi ʻole - Ferrous Metal Ore

1.Nickel Ore Flotation

• E like me ka mea i ʻōlelo ʻia ma mua, i ka nickel ore flotation, hoʻohana nui ʻia ka sodium hexametaphosphate e kāohi i ka serpentine. ʻO Serpentine kahi mineral gangue maʻamau i loko o nā ʻaila nickel, a hiki i kona hele ʻana ke hoʻopilikia i ka lele ʻana o nā minerala lawe nickel. Ma ka hoʻohui ʻana i ka sodium hexametaphosphate, hiki iā ia ke hana me nā ion metala ma ka ʻili serpentine, e hōʻemi ana i kona floatability a hoʻomaikaʻi i ka hoʻokaʻawale ʻana o nā minerala lawe nickel mai ka serpentine. He mea maikaʻi kēia no ka hoʻomaikaʻi ʻana i ka pae a me ka hoʻihoʻi hou ʻana o ka nickel concentrates.

2.Copper a me ke alakaʻi - Zinc Ore Flotation

• I ke keleawe a me ke kēpau - zinc ore flotation, i ka wā e pili ana i ka calcium - loaʻa nā mineral gangue e like me ka calcite a me ka dolomite, hiki ke hoʻohana ʻia ka sodium hexametaphosphate e kāohi i kēia mau mineral gangue. I kekahi mau keleawe paʻakikī - alakaʻi - zinc ores, hoʻoponopono i ka nui o ka sodium hexametaphosphate hiki ke hoʻomalu pono i ka floatability o nā mineral gangue, e hoʻomaikaʻi i ka koho o ka flotation a me ka maikaʻi o ke keleawe, ke kēpau, a me ka zinc concentrates.

Nā mea e pili ana i ka hopena noi

Hoʻoponopono

1.Optimal Dosage Determination

• He hopena koʻikoʻi ka nui o ka sodium hexametaphosphate i kāna hana i ka flotation mineral. Hiki ke alakaʻi i nā hopena maikaʻi ʻole ke ʻano kūpono ʻole. Inā haʻahaʻa loa ke ʻano, ʻaʻole hiki iā ia ke pale pono i nā minerala gangue a i ʻole e hoʻopuehu i ka pulp. No ka laʻana, i ka phosphate ore flotation, inā ʻaʻole lawa ka nui o ka sodium hexametaphosphate i hoʻohui ʻia, ʻaʻole hiki ke hoʻopaʻa maikaʻi ʻia nā mineral gangue, e hopena i ka haʻahaʻa haʻahaʻa o ka phosphate concentrate.

• Ma ka ʻaoʻao ʻē aʻe, inā kiʻekiʻe loa ka dosage, ʻaʻole hiki ke hoʻonui wale i nā kumukūʻai akā ke kumu i kekahi hopena maikaʻi ʻole. I kekahi mau hihia, hiki i ka nui o ka sodium hexametaphosphate ke keʻakeʻa i nā minerala i hoʻopaʻa ʻia i kekahi ʻano, e hōʻemi ana i ka helu hoʻihoʻi. No laila, ʻo ka hoʻoholo ʻana i ka dosage kūpono ma o ka noiʻi hoʻokolohua a me ka debugging ma ka pūnaewele he mea koʻikoʻi no ka loaʻa ʻana o nā hopena flotation maikaʻi loa.

pH Waiwai o ka Pulp

2. Ka hopena ma nā hoʻololi kemika

• Hoʻopili ka pH waiwai o ka pulp flotation i nā hopena kemika o ka sodium hexametaphosphate. Ma nā wahi pH like ʻole, hiki ke loli ke ʻano o ka ionization a me ke ʻano kemika o ka sodium hexametaphosphate. I loko o kahi ʻakika, hiki ke hoʻonāwaliwali ʻia kona hopena pale i kekahi mau mineral. I loko o kahi ʻano alkaline nui, hiki ke hana me nā mea ʻē aʻe i loko o ka pulp, e pili ana i kāna hana maʻamau. No ka laʻana, i ka lele ʻana o kekahi keleawe - ke kēpau - zinc ores, mālama i kahi waiwai pH kūpono (maʻamau ma kahi o 8 - 10) hiki ke hōʻoia i ka sodium hexametaphosphate e pale pono ai i nā minerala gangue a hoʻoikaika i ka lele ʻana o nā minerala.

Panina

He nui nā kuleana koʻikoʻi o ka sodium hexametaphosphate i ka flotation mineral, e like me ka a Kaumaha a me ka mea hoopuehu. ʻO kāna mau hoʻohana ʻana i nā ʻano like ʻole o ka mineral flotation, e like me ka phosphate ore a me ka non-ferrous metal ore flotation, ua hoʻomaikaʻi maikaʻi i ka pono a me ka maikaʻi o ka hoʻokaʻawale mineral. Eia nō naʻe, no ka hoʻokō piha ʻana i kona hiki, pono e mālama pono ʻia nā mea e like me ka dosage a me ka pulp pH. Me ka hoʻomau mau ʻana o ka ʻoihana mining, ʻoi aku ka noiʻi ʻana e pili ana i ka noi ʻana o ka sodium hexametaphosphate i ka flotation mineral hiki ke alakaʻi i nā ʻano hana hoʻoheheʻe mineral ʻoi aku ka maikaʻi a hoʻomau.
