Hoʻokahi mea e hoʻokumu ai nā mea a pau, ʻaʻole maikaʻi, ʻaʻole ia he maʻalahi ke hoʻohana. Eia kahi moʻolelo pōkole e pili ana i kahi hale hana hana kopa.

Akā, e noʻonoʻo ʻoe i ka wā e hoʻonui hou ai mākou i nā koi, ʻaʻole wale ka hoʻoponopono ʻana i ka pale ʻana i nā pahu kopa ʻole, akā e kuhikuhi wale i ka nui o ke kopa i hoʻokomo ʻia i loko o ka pahu kopa, a ua ʻōlelo ʻia ʻo loko o kēia ʻike ʻole. hoʻokomo ʻia ka pahu kopa i ke kopa. Inā hoʻokomo ʻia kahi kui, ʻaʻole hiki ke noʻonoʻo ʻia kēia koi i kēia manawa me ka mea hoʻonohonoho makani, a pono e hoʻohana ʻia kahi mea kaupaona ʻoi aku ka naʻauao a me ke kiʻekiʻe kiʻekiʻe e hoʻopau ai i kēia mau koi. He aha ke kānana naʻauao? E hoʻomanaʻo i ka hihia mua o ka holoi ʻana i nā strawberry, aia kahi hana koʻikoʻi i loko: ka hoʻokae ʻana i ka lolo kanaka. E ʻike pono ana ka lolo o kēlā me kēia kanaka inā he ʻino nā hua strawberry i ʻike ʻia a i ʻoki ʻia, a e alakaʻi pono i ka hoʻolālā hoʻolālā o ka lima no kēia.

Ma ke ala like, ʻo ka hana koʻikoʻi no nā huahana akamai ʻo ia ke aʻo ʻana i ka hāmeʻa e noʻonoʻo, i hiki iā ia ke hoʻokaʻawale i ka hoʻokaʻawale ʻana i ka hoʻokō ʻana o ka pahuhopu screening i nā lula. E lawe i ke kahua oka hao i laʻana e kūkākūkā ai pehea ka hana ʻana o ka mea kaupaona ʻeleʻele naʻauao? Ua māhele ʻia nā mining a pau ma koʻu ʻāina i nā mine metala laha loa, nā ʻoihana mining a me kā lākou mau mines intermediary, etc. ʻO ka lawe ʻana i ka ʻeli ʻana o nā mine metala laha ʻole ma ke ʻano he laʻana, pehea e loaʻa ai i nā ʻoihana mining nā pono waiwai? ʻO ka mua, ua ʻeli ʻia ka ʻaila maka mai loko mai o ka lua lanahu, a ua ʻoki ʻia ka ʻaila maka a wili ʻia i nā manawa he nui no ka loaʻa ʻana o nā mea kemika pauda me ka nui o nā mea like me ka palaoa palaoa. Loaʻa nā mea metala waiwai mai ka pauka hao, a ua kapa ʻia kēia kaʻina holoʻokoʻa i ke ʻano kaumaha ma ke kula. Hoʻopau kēia mau ʻanuʻu i ka nui o nā kumukūʻai e pili ana i ka wai, ka uila, ka lole a me ka waimaka o nā mīkini a me nā mea hana, nā pūhui kemika, a me nā limahana.

Ua kipa a noiʻi nā kānaka a pau i ka ʻeli ʻana o ʻelua a ʻekolu haneli mau mines ma Kina a loaʻa ka ʻikepili e pili ana ke kumukūʻai o hoʻokahi tona o ka ʻeli ʻana metala kaumaha ma kahi o 150 a i ʻole, pehea ka nui o nā pōmaikaʻi waiwai e hiki ai i hoʻokahi tona o ka hao hao? , 'o ia ho'i, ehia mau mea metala waiwai e hiki ke loaa? E nānā kākou i ka ʻikepili a me ka ʻike. ʻO koʻu ʻāina ka ʻāina mālama tungsten nui loa o ka honua. ʻOi aku ma mua o 90% o nā mines tungsten i koʻu ʻāina. ʻO ka ʻike tungsten o nā mines kālā i ʻike ʻia ma kahi māla ma kahi o 0.4%. He aha ka wehewehe ʻana o kēia? Ua hana au me ka luhi ole i ka'u, wili, a koho i 100 tona o ka hao. Ma waho aʻe o nā poho a pau i ka pae hoʻokahi, hiki iaʻu ke piʻi i ka 400kg o tungsten, a ʻo 0.4% o ka haku mele ʻana i ka ʻoihana tungsten no ke kālā kālā. , Nui nō hoʻi nā mines ʻaʻole hiki ke hiki i 400kg, a ʻo 400kg wale nō o ka tungsten hiki ke hoʻololi ʻia no 99.6 tons o ka ʻōpala. No laila, mai ka loaʻa ʻana o ka ʻoihana lanahu, ua noʻonoʻo ka poʻe loea i kahi pilikia paʻakikī, ʻo ia hoʻi, pehea e loaʻa ai ka waiwai hoʻohana ʻoi aku ke kūpono. ʻO kahi ala maʻalahi loa ka lawe ʻana i ka 100 tons o ka tungsten ore i kēia manawa ma ke ʻano he laʻana. ʻOkoʻa maoli ka ʻike o kēlā me kēia ʻāpana hao i ʻeli ʻia. He haʻahaʻa loa ka haʻahaʻa o nā mea metala kūpono a i ʻole nā ​​mea metala kūpono ʻole. Inā hiki ke hoʻopaʻa ʻia he 50 tons o ka hao hao me ka nui o ka ʻiʻo ʻo 380kg o ka tungsten i hōʻiliʻili ʻia i loko o ka hao hao, no laila, ʻo ka hāʻawi ʻana i nā 50 tons ʻē aʻe e ʻai i 20 kg o tungsten, akā mālama ia i ke kumukūʻai o 50 tons o ka hao. oka, a hoʻopiha i ka waiwai ʻO ka mana maikaʻi loa o ka waiwai, ʻo ia hoʻi, ʻo ia ka loaʻa ʻana o kahi waiwai hoʻohana ʻoi aku ka liʻiliʻi loa.

ʻO ka hoʻolālā wikiwiki loa, ʻoiaʻiʻo, ʻo ke koho ʻana i ka mana kanaka. ʻOiai ʻo ka hao hao e like me ka ʻiliʻili ma ka ʻaoʻao o ke alanui, he paʻakikī ke ʻike i ke ʻano o loko me nā maka, akā aia kekahi mau mines i kekahi mau hiʻohiʻona ili, no laila ʻo ka ʻenehana hana o ka koho lima ke kamaʻilio pū nei i nā mākau, mai nā mea he nui. ʻO nā ʻāina ʻEulopa ma mua o ke kenekulia hou a hiki i ka ʻeli ʻana o kēia makahiki ma koʻu ʻāina, aia nō ka nui o nā ʻoihana mining me ka nānā ʻana i koʻu ʻāina. Hoʻohana ʻia ka nui o nā limahana wahine i ka hana ʻana i nā mea kanu ʻaʻahu. Ke ʻimi nei kekahi mau mines i ka maikaʻi a ʻoi aku ka maikaʻi a me ka pololei, ua hoʻomaka lākou e hoʻopaʻa i kekahi mau papa hoʻolālā ʻōnaehana maʻalahi ʻole, e like me ka wai paipu. ʻO ka hoʻohana maʻamau o ka hoʻokaʻawale wai i loko o ka ʻoihana mining media. ʻO ka lanahu maʻemaʻe mai ka eli lanahu he kūlana kiʻekiʻe a haʻahaʻa. Kapa nā kānaka a pau he lanahu a me ka lanahu gangue. He ʻokoʻa ko lākou puʻuwai. ʻO ka hopena maʻalahi ka ninini ʻana i ka lanahu a pau i loko o ka lanahu me kekahi mau mea kemika. I nā mīkini a me nā mea hana, ʻo ka lanahu hoʻomaloʻo ea ma hope o ka unuhi ʻana he lanahu maikaʻi loa ia i kūʻai ʻia ma ka mākeke o kēia manawa. Kapa ʻia kēia hana holoʻokoʻa i ka hoʻomākaukau lanahu.

Akā ʻo kēia kaʻina hana holoʻokoʻa e hoʻopau i ka nui o ka wai a hoʻopau i ka pollution kūlohelohe i ke kaiapuni kūlohelohe. Eia kekahi, nui nā kumu lanahu ma koʻu ʻāina aia ma ka ʻāina ʻo Shanxi, a ʻaʻohe wai o Shanxi. No laila, ʻaʻole kānalua kēia he kumumanaʻo e hopu i ka iʻa a poina i ka iʻa. Ke hele nei i kahi ʻanuʻu, ke hoʻomaka nei ʻoukou e ʻimi i ka polokalamu no kahi ʻōnaehana sieving optical sensor-based.

Ke manaʻo nei mākou he pūʻulu o nā polokalamu ʻōnaehana hoʻonaʻauao akamai e hiki ke hoʻopau i ka nānā ʻana i ka hao hao kiʻekiʻe, a me ka mea hiki ke hana ʻia no ka mining. ʻO kaʻoiaʻiʻo, ua haʻi mua nā mea a pau i ke koi mua no ka nānāʻana,ʻo ia ka ho'ēmiʻana i ka hana a me ka mālamaʻana i nā kumukūʻai. Ma ka ʻaoʻao ʻē aʻe, no ka mea ʻaʻa ʻole ferrous plate ore, kahi ʻanuʻu nui i ke kaʻina holoʻokoʻa o ka concentrator ka mea kaumaha. , a ʻo ka mea kemika i loaʻa ma hope o ke ʻano kaumaha, ua kapa ʻia ke koena ʻōpala, ʻo ia ke ʻano o ka mea slurry i hui pū ʻia me nā pūhui like ʻole i like loa kona ʻano me ka momi sima. ʻO kēia ʻano hui pū kekahi mea luku nui i ke kaiapuni kūlohelohe. ʻO koʻu ʻāina koʻikoʻi ka nānā ʻana, a me ka hoʻohana ʻana i ka multihead weigher naʻauao, he wahi liʻiliʻi wale nō o ka ʻaila maka i hoʻolei ʻia i loko o ka wai ʻauʻau kaumaha e hana i ke koena ʻōpala, e hōʻemi ana i ka haumia o ka nohona o kēia ʻāpana mai ke kumu, no laila ka lua. ʻO ka pōmaikaʻi ʻo ia ka hōʻemi ʻana i ka pollution a pale i ke kaiaola.

E lawe i ka 100-ton tungsten ore i loko o 400kg i kēia manawa ma ke ʻano he laʻana.
