ʻIke nui e pili ana i nā pae oka
ʻO ka pae o ka ʻai e pili ana i ka ʻike o nā mea pono i loko o ka ʻai.Hōʻike maʻamau i ka pākēneka nui (%).Ma muli o nā ʻano minela like ʻole, ʻokoʻa nā ʻano o ka hōʻike ʻana i ka pae oka.ʻO ka hapa nui o nā mea metala, e like me ka hao, ke keleawe, ke kēpau, ka zinc a me nā ores ʻē aʻe, e hōʻike ʻia e ka pākēneka nui o ka ʻike metala;ua hōʻike ʻia ka pae o kekahi mau mea metala e ka pākēneka nui o kā lākou mau oxides, e like me WO3, V2O5, etc.Hōʻike ʻia ka pae o ka hapa nui o nā mineral non-metallic e ka pākēneka nui o nā minerala pono a i ʻole nā ​​​​huihui, e like me ka mica, asbestos, potash, alunite, etc.;ʻO ka helu o nā metala makamae (e like me ke gula, platinum) ores e hōʻike maʻamau i ka g / t ; ʻO ka helu o ka ʻai daimana mua i hōʻike ʻia ma mt/t (a i ʻole carat/ton, i hoʻopaʻa ʻia e like me ct/t);ʻO ka helu o ka placer ore ka mea maʻamau i hōʻike ʻia i nā grama no ke kenimika cubic a i ʻole kilokani no ka mika cubic.
ʻO ka waiwai noi o ka oka e pili kokoke ana i kona papa.Hiki ke hoʻokaʻawale ʻia ka Ore i loko o ka ʻeleʻele waiwai a me ka ʻeleʻele ʻilihune e like me ka papa.No ka laʻana, inā he ʻoi aku ka nui o ka hao hao ma mua o 50%, ua kapa ʻia ʻo ia he ʻeleʻele waiwai, a inā he 30% ka pae, ua kapa ʻia ʻo ia he ʻeleʻele ʻilihune.Ma lalo o kekahi mau kūlana ʻenehana a me ka hoʻokele waiwai, hōʻike pinepine ʻia ka pae ʻoihana o ka ʻeleʻele waiwai, ʻo ia hoʻi, ka pae ʻoihana liʻiliʻi loa.Ua pili loa kona mau lula i ka nui o ka waihona, ʻano oka, hoʻohana piha, hoʻoheheʻe ʻia a me ka ʻenehana hana, etc. tona.
ʻO ka papa hana ʻenehana e pili ana i nā mea pono i loaʻa nā pōmaikaʻi waiwai (hiki ke hōʻoiaʻiʻo i ka uku ʻana i nā koina like ʻole e like me ka ʻeli ʻana, ka lawe ʻana, ka hoʻoili ʻana a me ka hoʻohana ʻana) i loko o kahi poloka i hāʻawi ʻia i nā mea hoʻolaʻa hoʻokumu ʻia i loko o kahi papahana hoʻokahi (e like me ka wili ʻana a i ʻole ka ʻauwaha. ).Ka haʻahaʻa awelika maʻiʻo o ka mea.Hoʻohana ʻia ia no ka hoʻoholo ʻana i ka māka hiki ke hoʻihoʻi ʻia a i ʻole ke kaulike ʻoihana, ʻo ia hoʻi, ka māka i ka wā e like ai ka waiwai loaʻa o ka ʻai i ʻeli ʻia me nā koina hoʻokomo āpau a ʻo ka loaʻa kālā ʻana he ʻole.Ke hoʻololi mau nei ka papa ʻoihana me ka hoʻomohala ʻana i nā kūlana waiwai a me nā ʻenehana a me ke kiʻekiʻe o ka noi.No ka laʻana, mai ke kenekulia 19 a hiki i kēia manawa (2011), ua hāʻule ka helu ʻoihana o nā mines keleawe mai 10% a i 0.3%, a hiki i ka helu ʻoihana o kekahi mau waihona keleawe ākea ākea hiki ke hāʻule i 0. 2%.Eia kekahi, loaʻa i nā māka ʻoihana nā kūlana like ʻole no nā ʻano waihona mineral.
