Metala keleawe

ʻO ke keleawe kalakala

ʻO Cu (helu ʻātoma 29) he metala kahiko a nui loa i ʻike ʻia no kona ʻulaʻula-ʻalani metala ʻulaʻula, kiʻekiʻe conductivity, thermal conductivity, a me ka elasticity maikaʻi. Hoʻohana nui ʻia ia i nā uwea, nā mea uila, nā mea kūkulu hale, a me nā alloys. Hana maikaʻi nā ʻāpana keleawe e like me ke keleawe a me ke keleawe ma ka ʻoihana. ʻO ke keleawe ka lōʻihi a hiki ke hana hou ʻia a ua hoʻohana mua ʻia e hana i nā minerale e like me ka chalcopyrite a me ka turquoise. Komo ke keleawe i ka hanu a me ka hao i loko o ke kino kanaka, aia ma kahi o 0.01% o ka ʻōpala o ka Honua. He helu hehee ia o 1083 ℃ a me kahi paila o 2567 ℃.

Q1

He aha ka conductivity a me ka thermal conductivity o ke keleawe maʻemaʻe?

Re: ʻIke ʻia ke keleawe maʻemaʻe no kāna conductivity maikaʻi loa a me ka conductivity thermal. Ma ke ʻano o ka conductivity, ʻo ke keleawe maʻemaʻe kekahi o nā metala me ka conductivity kiʻekiʻe, ʻelua wale nō i ke kālā a me ke gula. Hana kēia i ke keleawe maʻemaʻe no ka hana ʻana i nā kaula a me nā ʻāpana uila a me ka uila, no ka mea hiki iā ia ke hoʻouna pono i kēia manawa me ka ʻole o ka wela nui. Hana maikaʻi ka keleawe maʻemaʻe ma ke ʻano o ka conductivity thermal a hiki ke hoʻololi koke i ka wela mai kahi wahi a i kekahi. Hana kēia ʻano i ke keleawe maʻemaʻe i nā noi hoʻokele wela e like me nā radiators, nā mea hoʻololi wela, a me nā mea wela.

Q2

He aha nā mea maikaʻi o nā hui keleawe (e like me ke keleawe a me ke keleawe) i hoʻohālikelike ʻia me ke keleawe maʻemaʻe?

Re: ʻO nā ʻāpana keleawe, e like me ke keleawe (copper-tin alloy) a me ke keleawe (copper-zinc alloy), he mau mea maikaʻi loa ma mua o ke keleawe maʻemaʻe. ʻO ka mea mua, ma ka hoʻohui ʻana i nā mea metala ʻē aʻe, hiki i nā ʻāpana keleawe ke hoʻomaikaʻi i nā waiwai mechanical o ke keleawe maʻemaʻe, e like me ka ikaika, ka paʻakikī, a me ke kūpaʻa. ʻOi aku ka maikaʻi o nā ʻāpana keleawe i nā noi ʻoihana e koi ana i nā ukana kiʻekiʻe a i ʻole nā ​​​​kaiapuni hana paʻakikī. ʻO ka lua, hiki i nā ʻāpana keleawe ke hoʻopaʻa i ko lākou mau uila, wela, a me ka corrosion kū'ē i nā waiwai ma o ka hoʻoponopono ʻana i nā ʻano a me nā ʻāpana o nā mea hoʻohuihui e hoʻokō i nā koi noi kikoʻī.

Q3

He aha nā mea e pili ana i ka hoʻokumu ʻana a me ka hāʻawi ʻana i nā waihona keleawe?

Re: ʻO nā kumu like ʻole e kahe ana ma luna o ka hoʻokumu ʻana a me ka hāʻawi ʻana i nā waihona keleawe. ʻO ka mea mua, ʻo ka nui o nā mea keleawe i loko o ka ʻōpala ke kumu kumu e hoʻoholo ai i ka hoʻokumu ʻana o nā waihona keleawe. ʻO ka lua, ʻo ka hana geological a me ka hana magmatic ka hopena i ka hoʻokumu ʻana i nā waihona keleawe. No ka laʻana, hiki i nā hana ʻāina e like me ka hui ʻana o ka pā a me ka pele pele ke hoʻoikaika i ka piʻi ʻana o ka pelemaka lawe keleawe a me ka paʻa paʻa ʻana, e hana ana i nā waihona keleawe. Eia kekahi, ʻo nā kaʻina hydrothermal a me ka sedimentary kekahi mau hana koʻikoʻi no ka hoʻokumu ʻana i nā waihona keleawe. ʻO ka hana hydrothermal e pili ana i ke kaʻina hana e lawe ai ka wai wela ma lalo o ka honua i nā mea keleawe ma luna o nā hewa a i ʻole nā ​​​​haʻihaʻi a hoʻoheheʻe ʻia e hana i nā waihona keleawe ma kahi hohonu ma ka ʻili a ma lalo paha. ʻO ka Sedimentation ke kaʻina hana e lawe ʻia ai nā mea keleawe e like me ka mea i hoʻoheheʻe ʻia a i ʻole nā ​​​​mea ʻala ma ka ʻili a i ʻole nā ​​​​kaiapuni o lalo o ka wai a hōʻuluʻulu mālie i loko o ka sediment, a laila e hana i nā waihona keleawe.

Q4

Pehea ka hoohana ana i na waiwai kino o ke keleawe, e like me ka manoanoa, ka helu hehee, a me ka paila?

Re: He hopena koʻikoʻi ka waiwai kino o ke keleawe i kāna mau noi. ʻO ka mea mua, he haʻahaʻa ka mānoanoa o ke keleawe (8.96 grams no ke kenimika cubic), ʻaʻole māmā a kaumaha loa, e lilo ia i mea kūpono i nā noi ʻenekinia. ʻO ka lua, he wahi hoʻoheheʻe kiʻekiʻe ke keleawe (1083 degere Celsius), ʻo ia ka mea hiki ke mālama i ke kūpaʻa maikaʻi ma nā wahi wela kiʻekiʻe a pili i nā mea hana e kū pono i nā wela kiʻekiʻe. Eia kekahi, he kiʻekiʻe ka paila o ke keleawe (2567 degere Celsius), hiki iā ia ke mālama i kahi ola lawelawe lōʻihi i ka wā o ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana. Hoʻoholo pū kēia mau waiwai kino i ka hoʻohana nui ʻana o ke keleawe ma nā māla e like me nā kaula, nā ʻāpana uila, nā mea kūkulu hale, a me ka hana ʻana i ka alloy.

Q5

He aha nā ʻanuʻu nui o ka hoʻoheheʻe keleawe?

Re: Ka unuhi ʻana i nā ʻaila keleawe mai nā mina keleawe. E ʻohi a wili i ka ʻaila i unuhi ʻia e hōʻemi i ka nui o kona ʻāpana, e maʻalahi ia no nā hana hoʻoheheʻe ma hope. Ke hoʻohana nei i ke ʻano flotation e hoʻokaʻawale i nā minela keleawe mai ka gangue i loko o ka ores. I ka wā o ke kaʻina hana flotation, hoʻohui ʻia nā mea hana flotation e hana i ka ili o nā ʻāpana mineral keleawe hydrophilic a i ʻole hydrophobic, a laila e hoʻokaʻawale iā lākou mai ka gangue. Hoʻoheheʻe pinepine ʻia nā mineral keleawe mai ka flotation me ka hoʻohana ʻana i ka pyrometallurgical a i ʻole nā ​​​​ʻano hoʻoheheʻe pulu. ʻO ka hoʻoheheʻe ahi ka hoʻoheheʻe ʻana i nā mineral keleawe ma nā mahana kiʻekiʻe e hoʻokaʻawale i ke keleawe mai nā mea haumia ʻē aʻe; Hoʻohana ka hoʻoheheʻe wai i nā hopena kemika e unuhi i ke keleawe mai nā ores. Pono e hoʻomaʻemaʻe ʻia ke keleawe maʻemaʻe i loaʻa mai ka hoʻoheheʻe ʻana i mea e hoʻomaikaʻi hou ai i ka maʻemaʻe o ke keleawe. I ka wā o ka hoʻomaʻemaʻe ʻana, ua hoʻoneʻe ʻia nā haumia i loko o ke keleawe keleawe e ka electrolysis a i ʻole nā ​​​​mea kemika ʻē aʻe. Hiki ke hoʻolei ʻia ke keleawe i hoʻomaʻemaʻe ʻia i loko o nā ʻano like ʻole o nā ingots keleawe a i ʻole nā ​​​​mea hana a hana hou ʻia i nā paipu keleawe a me nā uea.
